We briefly review the well known connection between classical chaos and classical statistical mechanics, and the recently discovered connection between quantum chaos and quantum statistical mechanics. Talk given at the Conference on Fundamental Problems in Quantum Theory Baltimore, June 18–22, 1994 Consider a dilute gas of hard spheres in a box with hard walls. Give the spheres some arbitrary i...

The Bohmian formulation of quantum mechanics is used in order to describe the measurement process in an intuitive way without a reduction postulate in the framework of a deterministic single system theory. Thereby the motion of the hidden classical particle is chaotic during almost all nontrivial measurement processes. For the correct reproduction of experimental results, it is further essentia...

We study Quantum Gravity effects on the density of states in statistical mechanics and its implications for critical temperature a Bose Einstein Condensate fraction bosons ground state. also compact extra dimensions fraction. consider both neutral charged show that may just be measurable current future experiments.

It is proved the mathematical theorem, that the wave function describes the statistical ensemble of particles, but not a single particle. Supposition, that the wave function describes a single particle appears to be incompatible with formalism of quantum mechanics. Interest to interpretation of quantum mechanics was very large from the very beginning of the quantum mechanics creation up to now....

Random quantum dynamics generates error correcting codes that are robust against observers and errors. Here, the authors describe a simple physical picture of such codes, mapping characteristic code properties to statistical mechanics fluctuating ``entanglement domain walls''. The criterion is understood as decoupling condition walls, which leads universal scaling law ``code distance''.
