Hermiticity
WitrynaThe word hermeticity as (for the lack of better definition, hence the question) “the quality of being hermetic” (not to be confused with mathematical hermiticity, which is also absent from the general dictionaries) seems to be widely used in technical literature.

Witryna9 sty 2024 · The interplay of topology and non-Hermiticity has led to diverse, exciting manifestations in a plethora of systems. In this work, we systematically investigate the role of non-Hermiticity in the Chern insulating Haldane model on a dice lattice. Due to the presence of a nondispersive flat band, the dice-Haldane model hosts a … Witryna15 sty 2024 · I'm trying to understand the concept of hermicity/self-adjointness but …
Witryna26 cze 2024 · In non-Hermitian (NH) quantum mechanics, Hamiltonians are studied whose eigenvalues are not necessarily real since the condition of hermiticity is not imposed. Certain symmetries of NH operators can ensure that some or all of the eigenvalues are real and thus suitable for the description of physical systems whose … WitrynaHermiticity thus never needs to be postulated at all. Currently there is much interest in Hamiltonians that are not Hermitian but instead possess an antilinear PT symmetry. Here we seek to put such PT symmetric theories into as general a context as possible. After providing a brief overview of the PT symmetry program, we show that having an ...
Witrynatopological invariants for bosonic systems with pseudo-time-reversal symmetry, which ensures the existence of bosonic counterparts of “Kramers pairs.” Because of the intrinsic non-Hermiticity of bosonic BdG systems, these topological invariants have to be defined in terms of the bosonic Berry connection and curvature.

This study is started from a photon-magnon model with a competition effect of the level attraction and repulsion, its Hermiticity is mainly decided by a phase-dependent and asymmetric coupling factor, namely ϕ = 0 for Hermitian and ϕ = π for non-Hermitian. Then an extensional study predicts the quantum critical …
