We introduce a planar waveguide of constant width with non-Hermitian PT-symmetric Robin boundary conditions. We study the spectrum of this system in the regime when the boundary coupling function is a compactly supported perturbation of a homogeneous coupling. We prove that the essential spectrum is...

这篇文章将Kane-Mele model进行相应的修改,往在位能里加入了gain and loss,从而将厄米系统变成了相应的非厄米系统,以得到复本征值,并就非厄米系统进行相应的一些研究,The resulting complex-eigenvalued edge state is robust against defects due to the topological protection.此外,In photonics, such an effect ...

K. A. Milton: PT -Symmetric Quantum Field Theory 4 Discussion It is not yet clear if there exists a consistent treatment of fermions in the PT - symmetric framework. The exploration of the Dirac equation, both at the classical and second-quantized level, promises to shed light on the conne...

Having an exact theory, and due to its relative experimental simplicity, PT-symmetric electronics offers new insights into the properties of PT-symmetric systems which are at the forefront of the research in mathematical physics and related fields. 展开 ...
PT-Symmetric Effective Model for Nonequilibrium Phase Transitions in a Dissipative Fermionic Mott Insulator ChainPhase transitions and critical phenomenaPhase transitions and critical phenomenaNonequilibrium phase transitions in open dissipative systems can be described as instabilities in the spectra and wave...
and, after a short introduction into the subject, present new results for a PT symmetric system of interest in holography: I will discuss our recent [1] investigation of the phase structure and the interaction induced quantum critical conductivity in a PT symmetric non-hermitian holographic metal....
We investigate a non- Hermitian finite-size Kitaev chain with PT-symmetric chemical potentials. Exact solution at the symmetric point shows that Majorana edge modes can emerge as the coalescing states at exceptional points and PT symmetry breaking states. The coalescing zero mode is the finite-size...
