Massively Degenerate Coherent Perfect Absorption in Gradient-Index Fibers
Helmut Hörner, Şahin K. Özdemir, Stefan Rotter
Coherent perfect absorbers (CPAs) have recently attracted considerable attention due to their ability to enhance light--matter interaction. By exploiting interference, CPAs enable…
Thermalization of quantum light induced by classical nonlinear wave dynamics
Fouad Chahrour, Şahin K. Ozdemir, Kurt Busch +2
Thermalization of isolated quantum systems is an intriguing phenomenon at the forefront of contemporary physics. In this work, we demonstrate that nonlinear multimode optical platf…
Exploring Nonreciprocal Noise Transfer under Onsager-Casimir Symmetry in Synthetic-Field Optomechanics
Beyza Sütlüoğlu Ege, Şahin K. Özdemir, Ceyhun Bulutay
An optomechanical system of fundamental importance consists of two intercoupled mechanical resonators, which are radiation-pressure coupled individually to a photonic cavity. This…
Topological state permutations in time-modulated non-Hermitian multiqubit systems with suppressed non-adiabatic transitions
Ievgen I. Arkhipov, Philippe Lewalle, Franco Nori +2
Non-Hermitian systems have been at the center of intense research for over a decade, partly due to their nontrivial energy topology formed by intersecting Riemann manifolds with br…
Parity-time symmetry breaking enables swarming motility in Caenorhabditis elegans
Mustafa Basaran, Tevfik Can Yüce, Ali Keçebaş +6
Nonreciprocal interactions break action-reaction symmetry in systems of interacting bodies. This process inevitably introduces non-Hermitian dynamics which with its hallmark signat…
Enhancement of quantum heat engine by encircling a Liouvillian exceptional point
J. -T. Bu, J. -Q. Zhang, G. -Y. Ding +10
Quantum heat engines are expected to outperform the classical counterparts due to quantum coherences involved. Here we experimentally execute a single-ion quantum heat engine and d…
Roadmap on structured waves
K. Y. Bliokh, E. Karimi, M. J. Padgett +47
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave.…
Scully-Lamb quantum laser model for parity-time-symmetric whispering-gallery microcavities: Gain saturation effects and non-reciprocity
Ievgen I. Arkhipov, Adam Miranowicz, Omar Di Stefano +4
We use a non-Lindbladian master equation of the Scully-Lamb laser model for the analysis of light propagation in a parity-time symmetric photonic system composed of coupled active…
Controllable optical response by modifying the gain and loss of a mechanical resonator and cavity mode in an optomechanical system
Yu-Long Liu, Rebing Wu, Jing Zhang +4
We theoretically study a strongly-driven optomechanical system which consists of a passive optical cavity and an active mechanical resonator. When the optomechanical coupling stren…
Controlling slow and fast light and dynamic pulse-splitting with tunable optical gain in a whispering-gallery-mode microcavity
Motoki Asano, Şahin Kaya Özdemir, Weijian Chen +4
We report controllable manipulation of slow and fast light in a whispering-gallery-mode (WGM) microtoroid resonator fabricated from Erbium (Er3+) doped silica. We observe continuou…
Optimal mirror phase-covariant cloning
Karol Bartkiewicz, Adam Miranowicz, Şahin Kaya Özdemir
We propose a quantum cloning machine, which clones a qubit into two clones assuming known modulus of expectation value of Pauli Z-matrix. The process is referred to as the mirror p…
Entangled states that cannot reproduce original classical games in their quantum version
Junichi Shimamura, Şahin Kaya Özdemir, Fumiaki Morikoshi +1
A model of a quantum version of classical games should reproduce the original classical games in order to be able to make a comparative analysis of quantum and classical effects. W…
