Quantum Coherent Absorption of Squeezed Light
Ali Ü. C. Hardal, Martijn Wubs
We investigate coherent perfect absorption (CPA) in quantum optics, in particular when pairs of squeezed coherent states of light are superposed on an absorbing beam splitter. Firs…
Phase-space interference in extensive and non-extensive quantum heat engines
Ali Ü. C. Hardal, Mauro Paternostro, Özgür E. Müstecaplıoğlu
Quantum interference is at the heart of what sets the quantum and classical worlds apart. We demonstrate that quantum interference effects involving a many-body working medium is r…
A quantum heat engine with coupled superconducting resonators
Ali Ü. C. Hardal, Nur Aslan, C. M. Wilson +1
We propose a quantum heat engine composed of two superconducting transmission line resonators interacting with each other via an optomechanical-like coupling. One resonator is peri…
Renyi divergences, Bures geometry and quantum statistical thermodynamics
Ali Ü. C. Hardal, Özgür E. Müstecaplıoğlu
The Bures geometry of quantum statistical thermodynamics at thermal equilibrium is investigated by introducing the connections between the Bures angle and the Renyi -divergenc…
Einstein-Podolsky-Rosen steering in non-Hermitian, nonlinear soliton surface plasmons
Ali Ü. C. Hardal
We investigate the dynamics of Einstein-Podolsky-Rosen steering in a soliplasmonic system where the asymmetrical coupling between linear solitons and nonlinear plasmons is controll…
Superradiant Quantum Heat Engine
Ali Ü. C. Hardal, Özgür E. Müstecaplıoglu
Quantum physics revolutionized classical disciplines of mechanics, statistical physics, and electrodynamics. One branch of scientific knowledge however seems untouched: thermodynam…
Dynamics of mode entanglement in a system of cavities coupled with a chiral mirror
Ali Ü. C. Hardal
We investigate the Hermitian and the non-Hermitian dynamics of the mode entanglement in two identical optical cavities coupled by a chiral mirror. By employing the non-Hermitian qu…
Quantum correlated heat engine with nonlinear spin-spin interactions
Ferdi Altintas, Ali Ü. C. Hardal, Özgür E. Müstecaplıoğlu
We propose a four level quantum heat engine in Otto cycle with a working substance of two spins subject to an external magnetic field and coupled to each other by a one-axis twisti…
Rabi model as a quantum coherent heat engine: From quantum biology to superconducting circuits
Ferdi Altintas, Ali Ü. C. Hardal, Özgür E. Müstecaplıoğlu
We propose a multilevel quantum heat engine with a working medium described by a generalized Rabi model which consists of a two-level system coupled to a single mode bosonic field.…
Spin squeezing, entanglement and coherence in two driven, dissipative, nonlinear cavities coupled with single and two-photon exchange
Ali Ü. C. Hardal, Özgür E. Müstecaplıoglu
We investigate spin squeezing, quantum entanglement and second order coherence in two coupled, driven, dissipative, nonlinear cavities. We compare these quantum statistical propert…
Discrete time quantum walk with nitrogen-vacancy centers in diamond coupled to a superconducting flux qubit
Ali Ü. C. Hardal, Peng Xue, Yutaka Shikano +2
We propose a quantum-electrodynamics scheme for implementing the discrete-time, coined quantum walk with the walker corresponding to the phase degree of freedom for a quasi-magnon…
Transfer of spin squeezing and particle entanglement between atoms and photons in coupled cavities via two-photon exchange
Ali Ü. C. Hardal, Özgür E. Müstecaplıoğlu
We examine transfer of particle entanglement and spin squeezing between atomic and photonic subsystems in optical cavities coupled by two-photon exchange. Each cavity contains a si…
