Quantum theory of many-particle systems Alexander L. Fetter, John Dirk Walecka

References: Griffiths In statistical mechanics the central assumption is that all states with a given energy are equally probable, if the system is in thermal equilibrium, which means that it is not exchanging energy with its surroundings. Statistical mechanics in quantum theory: counting states. Though counterintuitive (Phys.org) —When two parties use a quantum system to share information, the amount of quantum information that can be communicated is fundamentally limited by quantum properties.

The basic idea is to conceive of memory states in terms of states of many-particle systems, as inequivalent representations of vacuum states of quantum fields.

But according to the quantum Zeno paradox (QZP), an unstable particle that is observed continuously has been said to never decay. In principle, using a quantum approach to predicting the behavior of a macroscopic (large mass) localized particle would be expected to yield the same answer as a classical approach. This is quite a hefty In classical physics, the allowed energy levels for a collection of particles form a continuous set, so there are infinitely many possible states. His research is centered on the theoretical physics of quantum many-particle systems in which interactions are qualitatively important and lead to novel behavior. Fetter, John Dirk Walecka, Quantum. Indeed the When the mass is very small classical physics breaks down, but this does not mean quantum physics breaks down at large scales and indeed, despite many experiments to isolate a mesoscopic region where quantum physics breaks down, no such region has been found. And when it comes to quantum physics, "macroscopic" objects are considered . I am trying to understand pure and mixed states better. The theory also suggests that a single measurement may affect two remote, distinct systems described by "entangled" quantum states. Now in a new paper, of atoms it contains.
