In subject area: Physics and Astronomy Quantum statistics refers to the statistical physics that influences critical behavior near various types of phase transitions, particularly quantum phase transitions, where quantum mechanical effects play a significant role in the thermodynamic and correlation properties...
Atoms are built up of successive orbital shells of electrons, labeled by the principal quantum number n and the angular quantum numbers lm, which are less and less tightly bound to the nucleus. From: Encyclopedia of Condensed Matter Physics, 2005 ...
I believe this applies to photons and particles in general. The equations for physics always seem to allow collisions to be reversable and there are no laws that would not allow any set of particle interactions to be reversible. However, it is my opinion that photons are not reversible for t...
a physics professor at the University of Illinois Urbana-Champaign (UIUC) and the director of itsCenter for Quantum Sensing and Quantum Materials, a Department of Energy Frontier Research Center. “It’s not like they’re a new phase of material. But we can’t even begin to explain...
The objection is the hypothetical and counterfactual idea of time reversibility. If time were reversed, the entropy would simply decrease. Since the fundamental Newtonian equations of motion are time reversible, this appears to be a paradox. How could the irreversibile increase of the macroscopic ...
The Schrodinger equation came about when more evidence was being presented about wave-particle duality. Schrodinger thought that if particles could behave as waves, there should be an equation that describes them as such. Using other equations for inspiration, Schrodinger was able to come up with ...
The physics underlying each scheme is instructive, with valuable lessons for the quantum informationists to heed. Various proposed quantum information processing platforms have characteristic strengths and weaknesses, which are clearly delineated in this book. For now it is important to pursue a ...
Physics needs more scientists like Assa: nose to the wind, energetic, low on arrogance. Someone who’d respond to this story of frustration with that broad smile. Last August, Toronto’sCentre for Quantum Information and Quantum Control(CQIQC) gave me 35 minutes to make fun of John Preskill...
Why is Excel giving me a wrong solution to a system of equations? Generalization of a mind-boggling box-opening puzzle There is mathematics in physics but is there any physics in mathematics? What is this mysterious bar in my hotel shower? Is it a coincidence that the smallest bit of...
In this answer I'm going to assume quantum mechanical equations of motion actually describe reality. If a quantum system is evolving without interacting with other systems to a good approximation, then it may exhibit a process called quantum interference. This means that in...
