Shortcuts to adiabaticity with general two-level non-Hermitian systems

TZ Luan, HZ Shen, XX Yi - Physical Review A, 2022 - APS
Shortcuts to adiabaticity are alternative fast processes which reproduce the same final state
as the adiabatic process in a finite or even shorter time, which have been extended from …

Optimizing the relaxation route with optimal control

A Prados - Physical Review Research, 2021 - APS
We look into the minimization of the connection time between nonequilibrium steady states.
As a prototypical example of an intrinsically nonequilibrium system, a driven granular gas is …

Single-atom transport in optical conveyor belts: Enhanced shortcuts-to-adiabaticity approach

SH Hauck, G Alber, VM Stojanović - Physical Review A, 2021 - APS
Fast and nearly lossless atomic transport, enabled by moving the confining trap, is a
prerequisite for many quantum-technology applications. While theoretical studies of this …

Dynamical approach to shortcuts to adiabaticity for general two-level non-Hermitian systems

TZ Luan, JY Sun, HZ Shen - Europhysics Letters, 2023 - iopscience.iop.org
In this Letter, we apply a class of general two-level non-Hermitian Hamiltonians whose off-
diagonal elements are neither equal nor conjugate of each other to study the dynamical …

[HTML][HTML] Thermal brachistochrone for harmonically confined Brownian particles

A Patrón, A Prados, CA Plata - The European Physical Journal Plus, 2022 - Springer
The overdamped Brownian dynamics of a harmonic oscillator is a paradigmatic system in
non-equilibrium statistical mechanics, which reliably models relevant stochastic systems …

Minimum time connection between non-equilibrium steady states: the Brownian gyrator

A Patrón, CA Plata, A Prados - Journal of Physics A …, 2024 - iopscience.iop.org
We study the problem of minimising the connection time between non-equilibrium steady
states of the Brownian gyrator. This is a paradigmatic model in non-equilibrium statistical …

Fast and robust particle shuttling for quantum science and technology

L Qi, J Chiaverini, H Espinós, M Palmero… - Europhysics …, 2021 - iopscience.iop.org
We review methods to shuttle quantum particles fast and robustly. Ideal robustness amounts
to the invariance of the desired transport results with respect to deviations, noisy or …
