Hermiticity
WitrynaThe 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 non-dispersive flat band, the dice-Haldane model hosts a topologically rich phase … WitrynaIn mathematics, a self-adjoint operator on an infinite-dimensional complex vector …

Witryna4 lut 2013 · Similarly, γ 5-hermiticity is commonly used as an Hermite condition, but we cannot forbid non-Hermite or complex couplings directly. A kinetic term that reduces the number of doublers allows the possibility of generating these anti-Hermite effective coupling constants. R-hermiticity is a criterion to remove non-hermiticity. 3. Conclusion WitrynaDuring the recent wave of optimism people started believing that the corridors of a unitary access to the EPs could be opened leading, say, to a new picture of quantum phase transitions via an {\it ad hoc} weakening of the Hermiticty (replaced by the …

Witryna6 lut 2024 · Induced by the non-Hermiticity, the system undergoes a sequence of -symmetry breakings, after which the eigenenergies appear in complex conjugate pairs. The associated extended bulk states then become scale-free localized and unidirectionally accumulated around the impurity. There exist mobility edges … WitrynaHermiticity breaking , which can be transformed into a Hermitian system that thermalizable. The equilibrium state of the quasi-Hermitian system is de ned as the steady state of the thermalizable thermal non-Hermitian system. In most cases, systems without quasi-Hermiticity breaking satisfy de nition 2, due to the

We point out that all the PT-symmetric non-Hermitian Hamiltonians studied in the literature belong to the class of pseudo-Hermitian Hamiltonians, and argue that the basic structure … china lake naval base newsWitrynaThe word hermeticity as (for the lack of better definition, hence the question) “the … china lake naws commissaryWitrynaMoreover, we show that the non-Hermiticity can drive a flux-dependent topological transition characterized by a hidden Chern number.
