Path Integral studies of quantum systems at finite temperatures Sergei Dmitrievich Ivanov
... The idea of the PIs applied for quantum and statistical mechanics was suggested and developed by one of the most brilliant scientists of the twentieth century Richard Feynman [1, 2]. Feynman himself used PI mostly for illustration of the basic concepts of quantum mechanics and its relation to classi ...

Deformed Generalization of the Semiclassical Entropy
... Wehrl entropy is simply the “classical entropy” (1) of a Wigner-distribution. Indeed, µ(x, p) is a Wignerdistribution DW smeared over an ~ sized region of phase space [21]. The smearing renders µ(x, p) a positive function, even if DW does not have such a character. The semi-classical Husimi probabil ...

It could happen that H = H0 + Vint does not possess particle-like eigenstates at all (or not all of its eigenstates are particle-like). This is indeed so in conformal field theory models or ...
