Nonreciprocal Control of the Goos--Hänchen Shift via the Barnett Effect in Cavity Magnomechanics
Shah Fahad, Gao Xianlong
We propose a theoretical scheme for realizing a tunable nonreciprocal Goos-Hänchen shift (GHS) in a hybrid cavity magnomechanical system. The setup consists of a rotating yttrium i…
Finite-size reliability of homothetic quantum Otto engines
Gabriella G. Damas, Clebson Cruz, Norton G. de Almeida +2
Homothetic quantum Otto engines---where all populated energy gaps are rescaled by a common factor---provide a reference model in which the quasistatic stochastic efficiency is traj…
Coherence-Preserving Fluctuation Diagnostics for an Engineered Population-Inverted Qubit Otto Engine
Gabriella G. Damas, Norton G. de Almeida, Gao Xianlong +1
Finite-time quantum thermal machines require diagnostics beyond average work and efficiency, because microscopic engines operate in regimes where fluctuations, incomplete thermaliz…
Goos-Hänchen Shift in -Symmetric and Passive Cavity Optomechanical Systems
Shah Fahad, Gao Xianlong
We theoretically investigate the control of the Goos-Hänchen shift (GHS) of a reflected weak probe field in both parity-time ()-symmetric and conventional optomechan…
Coherent Control of the Goos-Hänchen Shift in Polariton Optomechanics
Shah Fahad, Gao Xianlong
We propose a theoretical scheme for controlling the Goos-Hänchen shift (GHS) of a reflected probe field in a polariton optomechanical system. The system comprises an optical mode,…
-assisted control of Goos-Hänchen shift in cavity magnomechanics
Shah Fahad, Gao Xianlong
We propose a scheme to manipulate the Goos-Hänchen shift (GHS) of a reflected probe field in a non-Hermitian cavity magnomechanical system. The platform consists of a yttrium-iron…
