Green Function Techniques in the Treatment of Quantum Transport
... Green function (NGF) techniques [66, 73–76]. The former also lead to more simple rate equations in the case where (i) the electrode-system coupling can be considered as a weak perturbation, and (ii) off-diagonal elements of the reduced density matrix in the eigenstate representation (coherences) can ...

Yet, there is no special objection why quantum mechanics should not be generally applicable, even to macroscopic systems. Indeed, macroscopic phen ...

... Most textbooks on modern physics and quantum mechanics have a discussion of quantum tunneling. The discussion is remarkably similar throughout these books, with the main difference being that modern physics textbooks give less detail. Tunneling is defined as a wave function passing through a potenti ...

Topological aspects of systems with broken time-reversal symmetry

Thus, when time-reversal symmetry is broken, the wave function is generically a complex function with both an amplitude and a spatially-varying phase, and could permit non-analytic, “vortex-like” de ...
