supported by: What's new: We develop a general theory for Mott criticality of bosons at half filling on the triangular lattice. (6/18/05) In the previous posting, we described the discovery of a supersolid phase of the XXZ model on the triangular lattice, even in the limit of infinitely strong interactions. But the superfluidity is amazingly weak - so we think of this as an indication the system is close to a quantum phase transition to a Mott insulator, where the superfluidity would vanish. This closeness would neatly explain the strange observations remarked on below. We (Anton Burkov and LB) have developed a general theory of the quantum critical points in half-filled boson systems on the triangular lattice. There are a number of interesting Mott transitions that can occur, from the superfluid directly to a Mott state, or from different supersolids to Mott states. All the transitions we found in this way are "exotic", i.e defy the Landau-Ginzburg-Wilson (LGW) paradigm, and can be thought of in one way or another as "deconfined" quantum critical points.

Welcome to the NASA Breakthrough Propulsion Physics (BPP) Project Public Information Site To see more BPP artwork click on the picture ABOUT BPP NASA supported the Breakthrough Propulsion Physics Project from 1996-2002 to seek the ultimate breakthroughs in space transportation: (1) propulsion that requires no propellant mass, (2) propulsion that attains the maximum transit speeds physically possible, and (3) breakthrough methods of energy production to power such devices. Topics of interest include experiments and theories regarding the coupling of gravity and electromagnetism, the quantum vacuum, hyper fast travel, and super luminal quantum effects. Because the propulsion goals are presumably far from fruition, a special emphasis is to identify affordable, near-term, and credible research that could make measurable progress toward these propulsion goals. This web site describes the methods and activities of the Breakthrough Propulsion Physics Project.

167. Theories With Problems By Keith Mayes Examination of theories in physics from the Big Bang to quantum Theory, time travel, superluminal speed and Time itself. http://www.thekeyboard.org.uk

THEORIES WITH PROBLEMS by Keith Mayes Paperback now on sale The Big Bang, Quantum Mechanics, Relativity, Time, Light Speed, Gravity, Electromagnetism, all have their theories that attempt to explain why these things are the way they are. These theories form part of our understanding of the fundamental laws of the universe, but are of course unable to provide all the answers we seek. All theories have problems in that they cannot be proven to be absolutely correct, they do not necessarily accurately describe the way things really are. They are constructed as a working model that is a useful aid to our understanding, of observed phenomenon and as a method of predicting future outcomes. When a theory is found to be wrong, it is either discarded, or as is more generally the case, modified, until it again appears to match the observations. A theory, no matter how well it appears to accurately describe any phenomenon, is provisional, it can never be proven to be completly correct, but it may be proven wrong. It will therefore always be impossible to claim a final theoretical solution to anything. "As being is to becoming, so is truth to belief. If then, Socrates, amid the many opinions about the gods and the generation of the universe, we are not able to give notions which are altogether and in every respect exact and consistent with one another, do not be surprised. Enough if we deduce probabilities as likely as any others; for we must remember that I who am the speaker and you who are the judges are only mortal men". (Plato)

Main Physics Contents page Special Relativistic Paradoxes The Barn and the Pole The Twin Paradox The Superluminal Scissors Relativity and Quantum Mechanics Contents The Barn and the Pole Updated 4-AUG-1992 by SIC Original by Robert Firth Paradoxes Contents These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer. You are that observer, sitting on the barn roof. You see the pole coming towards you, and it has contracted to a bit less than 40m. So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed. But consider the problem from the point of view of the runner. She will regard the pole as stationary, and the barn as approaching at high speed. In this reference frame, the pole is still 80m long, and the barn is less than 20 meters long. Surely the runner is in trouble if the doors close while she is inside. The pole is sure to get caught.

170. The EPR Paradox And Bell's Inequality Principle Does Bell's Inequality Principle rule out local theories of quantum mechanics? http://math.ucr.edu/home/baez/physics/Quantum/bells_inequality.html

[Physics FAQ] Updated May 1996 by PEG (thanks to Colin Naturman). Updated August 1993 by SIC. Original by John Blanton. Does Bell's Inequality Principle rule out local theories of quantum mechanics? In 1935 Albert Einstein and two colleagues, Boris Podolsky and Nathan Rosen (EPR) developed a thought experiment to demonstrate what they felt was a lack of completeness in quantum mechanics. This so-called "EPR paradox" has led to much subsequent, and still on-going, research. This article is an introduction to EPR, Bell's inequality, and the real experiments that have attempted to address the interesting issues raised by this discussion. One of the principal features of quantum mechanics is that not all the classical physical observables of a system can be simultaneously known with unlimited precision, even in principle. Instead, there may be several sets of observables which give qualitatively different, but nonetheless complete (maximal possible) descriptions of a quantum mechanical system. These sets are sets of "good quantum numbers," and are also known as "maximal sets of commuting observables." Observables from different sets are "noncommuting observables". A well known example is position and momentum. You can put a subatomic particle into a state of well-defined momentum, but then you cannot know where it is. It's not just a matter of your inability to measure, but rather, an intrinsic property of the particle. Conversely, you can put a particle in a definite position, but then its momentum is completely ill-defined. You can also create states of intermediate knowledge of both observables: if you confine the particle to some arbitrarily large region of space, you can define the momentum more and more precisely. But you can never know both, exactly, at the same time.

2. Some Basic Ideas about Quantum Mechanics Modern physics is dominated by the concepts of Quantum Mechanics. This page aims to give a brief introduction to some of these ideas. Until the closing decades of the last century the physical world, as studied by experiment, could be explained according to the principles of classical (or Newtonian) mechanics: the physics of everyday life. By the turn of the century, however, the cracks were beginning to show and the disciplines of Relativity and Quantum Mechanics were developed to account for them. Relativity came first, and described the physics of very massive and very fast objects, then came Quantum Mechanics in the 1920's to describe the physics of very small objects. Neither of these theories provide an easy intuitive picture of the world, since they contradict the predictions of familiar Newtonian Mechanics in the regimes for which they were developed. Nevertheless, both schemes reproduce the Newtonian results when applied to the everyday world. In seeking to understand the physics of semiconductors at an atomic level we must start from a Quantum Mechanical viewpoint, since the entities with which we will be dealing (electrons, atoms, etc) are so very small....

177. Karl Popper, 1902--1994 Philosopher of science, author of quantum Theory and the Schism in physics http://www.santafe.edu/~shalizi/notebooks/popper.html

Notebooks Karl Popper, 19021994 14 Apr 2003 14:00 Austrian-English philosopher, dead, alas, just as I began these notebooks. Popper was primarily a philosopher of science; his system, that of "conjectures and refutations," of falsification, was elegant, coherent, and basically right-headed. Similar to that of such earlier methodologists as William Whewell and Claude Bernard (as Popper was among the first to admit), it was one of only three which, in this century, actual scientists have bothered to pay attention to, and easily the best of them, both in its intellectual quality and its effects. (The other two were the system of Kuhn, who set out to turn Popper upside down; and Machian positivism and its descendants, including the Vienna Circle of logical positivists , who Popper hung out with, but on many important points disagreed with. Positivism was restrictive but, aside from encouraging the behaviorists, mostly harmless; the latter, through no fault of Kuhn's own, has led to no good at all. - Of course, many scientists have been forced to pay attention to dialectical materialism, but on purely prudential, not intellectual, grounds; that doesn't count.) Even now, querying scientists about what they're up to is very likely to provoke more or less Popperian responses. That said, there are enough problems with it that I, for one, can't really accept it, and there are very few proper Popperians left among professional philosophers of science. On the other hand, his critism of such pretenders to scientific status as Marxism, the "sociology of knowledge" and, especially

WELCOME TO THE COLLECTED WORKS OF BERT SCHREIBER (1924 -) Welcome to this site. The main point herein is my NEW physics theory that destroys all previous physics theories and replaces them with one simple theory. In addition there were other (new) mathematical discoveries as side results from this theory. I, for all theoretical purposes, demolished the current immaculate mathematical theory and its current applications, especially in physics, in more ways than one. There are also what I call FUN PAPERS which are satires of the current scientific establishment. The first one is actually the first chapter in my book disguised in non-scientific lingo. The SIDE PAPERS contain a few short versions of some of the major discoveries that I made. The full proofs are in my book. Other papers of importance, especially the one on "the scientific method"[1.] and the paper [2.] following. Next is my "reward" called EASY MONEY II which has a very few of my discoveries (pro and con) that no one has been able to collect on. Maybe you can be the first one to collect the $2,000.00 per item as listed. Next are a few selected ARTICLES that were from the results of all of my works and experiences in life.
