Quantum Otto engines at relativistic energies

NM Myers, O Abah, S Deffner - New journal of physics, 2021 - iopscience.iop.org
Relativistic quantum systems exhibit unique features not present at lower energies, such as
the existence of both particles and antiparticles, and restrictions placed on the system …

Shortcuts in stochastic systems and control of biophysical processes

E Ilker, Ö Güngör, B Kuznets-Speck, J Chiel, S Deffner… - Physical Review X, 2022 - APS
The biochemical reaction networks that regulate living systems are all stochastic to varying
degrees. The resulting randomness affects biological outcomes at multiple scales, from the …

Thermodynamics of statistical anyons

NM Myers, S Deffner - PRX Quantum, 2021 - APS
In low-dimensional systems, indistinguishable particles can display statistics that interpolate
between bosons and fermions. Signatures of these “anyons” have been detected in two …

Nanowelding of quantum spin- chains at minimal dissipation

MF Cavalcante, MVS Bonança, E Miranda, S Deffner - Physical Review B, 2024 - APS
We consider the optimal control of switching on a coupling term between two quantum many-
body systems. Specifically, we (i) quantify the energetic cost of establishing a weak junction …

Environment-assisted shortcuts to adiabaticity

A Touil, S Deffner - Entropy, 2021 - mdpi.com
Envariance is a symmetry exhibited by correlated quantum systems. Inspired by this
“quantum fact of life,” we propose a novel method for shortcuts to adiabaticity, which enables …

Shortcuts to adiabatic population inversion via time-rescaling: stability and thermodynamic cost

J da Silva Andrade, ÂF da Silva França… - Scientific Reports, 2022 - nature.com
A shortcut to adiabaticity is concerned with the fast and robust manipulation of the dynamics
of a quantum system which reproduces the effect of an adiabatic process. In this work, we …

Acceleration and deceleration of quantum dynamics based on inter-trajectory travel with fast-forward scaling theory

S Masuda, J Koenig, GA Steele - Scientific Reports, 2022 - nature.com
Quantum information processing requires fast manipulations of quantum systems in order to
overcome dissipative effects. We propose a method to accelerate quantum dynamics and …

Shortcuts to adiabaticity designed via time-rescaling follow the same transitionless route

JL Ferreira, ÂF França, A Rosas… - arXiv preprint arXiv …, 2024 - arxiv.org
Time-rescaling (TR) has been recently proposed as a method to engineer fast processes,
also known as shortcuts to adiabaticity (STA), which enables the coherent control of …

Fast Driving of a Particle in Two Dimensions without Final Excitation
