The Quantum Spin Hall Effect
... So far, the QSH insulator is a topologically non-trivial band insulator. Can we have a topological Mott insulator, where the topologically non-trivial gap arises from interactions, not from band structure? Yes, on a honeycomb lattice with U, V1 and V2, one can obtain a TMI phase in the limit of V2>> ...

We assume that the frequency co of the variable electric field as well as the interaction with all external fields are small compared with the separation between level n of energy ELo) and the neighboring ...

... • Decoherence can be viewed as the loss of information from a system into the environment (often modeled as a heat bath). It is thus acknowledged that no system is, in reality, perfectly isolated—but rather every system is loosely coupled with the energetic state of its surroundings. Viewed in isola ...
