We demonstrate experimentally that stable single longitudinal mode operation can be readily achieved in PT-symmetric arrangements of coupled microring resonators. Whereas any active resonator is in principle capable of displaying single-wavelength operation, selective breaking of PT-symmetry can be utilized ...
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 ...

We propose a new type of wireless displacement sensor based on the concept of parity-time (PT)-symmetry. The PT-symmetric wireless sensor consists of a -RLC tank (reader) and a RLC (tag) tank, which are inductively coupled to fulfill the PT-symmetry condition. Specifically, when this wirel...
By applying the higher order Darboux algorithm to an exactly solvable non-Hermitian PT symmetric potential, we obtain a hierarchy of new exactly solvable non-Hermitian PT symmetric potentials with real spectra. It is shown that the symmetry underlying the potentials so generated and the original one...
Metrology withPT-Symmetric Cavities: Enhanced Sensitivity near thePT-Phase Transition We propose and analyze a new approach based on parity-time (PT) symmetric microcavities with balanced gain and loss to enhance the performance of cavity-assisted metrology. We identify the conditions under which PT-...

In the present work, we explore the case of a general PT-symmetric dimer in the context of two both linearly and nonlinearly coupled cubic oscillators. To obtain an analytical handle on the system, we first explore the rotating wave approximation converting it into a discrete nonlinear Schr"...
