This model, which can be realized with current technology in photonics using waveguides, allows us to study Floquet topological insulating phase. By using Floquet theory, we find the quasi-energy spectrum of this one dimensional PT symmetric topological insulator. We show that stable Floquet ...
We study the parity- and time-reversal PT symmetric non-HermitianSu-Schrieffer-Heeger (SSH) model with two conjugated imaginary potentials $\\pmi\\gamma $ at two end sites. The SSH model is known as one of the simplesttwo-band topological models which has topologically trivial and nontrivial...
The Pt surface model contains 7 Pt atomic layers as illustrated in Figure S3A. The bottom three layers (pink colored balls) are fixed to mimic the bulk effect. Accounting the structural symmetric of Pt (111) sur- face, there are two representative binding sites for a foreign atom as ...

Thus, as we demonstrate here, in PT-symmetric chiral metamaterials a wide range of advanced polarization control capabilities is possible. 2. Physical Model and Main Equations 2.1. PT-Symmetry Conditions in Chiral Systems In order to examine if there is a possibility to achieve PT-symmetry in ...

expect. pexpect allows your script to spawn a child application and control it as if a human were typing commands. pexpect can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. it can be used to automate setup scripts for duplicating software package ...
It uses symmetric key cryptography and requires a trusted Key Distribution Center (KDC) to authenticate users and services. Unlike AUTH_SYS, with the RPCSEC_GSS Kerberos mechanism, the server does not depend on the client to correctly represent which user ...
We show that topological phase exist in non-Hermitian PT symmetric systems for both gapped and gapless systems and discuss appearance of exceptional points. We apply our formalism to a complex extension of the SSH model, topological semimetals and nodal superconductors....
Energy band structures of one-dimensional non-Hermitian spin- orbit-coupled Su-Schrieffer-Heeger (SSH) model are theoret-ically investigated, by introducing imaginary potentials with gain and loss effects. It is found that the imaginary potentials can promote the occurrence of PT-symmetry breaking....
