Biorthogonality of Guided Modes in Non-Hermitian Electromagnetism
Amgad Abdrabou, M. A. Swillam, Şahin K. Özdemir +1
Biorthogonality plays a central role in the analysis of non-Hermitian photonic systems, where modal expansions generally require both right and left eigenstates. While these concep…
Classifying Topology via Edge-State Pure Thermalization
Fatih Ozaydin, Haydar Sahin, Armando Perez-Leija +4
Repeated-interaction machines distinguish heat-like from work-like resources through the steady states they generate, but whether topology can control this distinction remains unkn…
Engineering Non-Hermitian Quantum Evolution Using a Hermitian Bath Environment
Mahmoud A. Selim, Max Ehrhardt, Yuqiang Ding +9
Engineering quantum bath networks through non-Hermitian subsystem Hamiltonians has recently emerged as a promising strategy for qubit cooling, state stabilization, and fault-tolera…
Localised Thermal Emission from Topological Interfaces
M. Said Ergoktas, Ali Kecebas, Konstantinos Despotelis +7
The control of thermal radiation by shaping its spatial and spectral emission characteristics plays a key role in many areas of science and engineering. Conventional approaches to…
Exceptional points-based optical amplifiers
Q. Zhong, S. K. Ozdemir, A. Eisfeld +2
The finite gain-bandwidth product is a fundamental figure of merit that restricts the operation of standard optical amplifiers. In microcavity setups, this becomes a serious proble…
