Explicit closed-form propagators for time-dependent gain-loss master equations
Léonce Dupays
Time ordering is a central obstacle in driven open-system dynamics governed by master equations with time-dependent rates. We derive explicit closed-form factorizations of the chro…
Field-Space Entanglement Dynamics Between Tunnel-Coupled Luttinger Liquids
Léonce Dupays, Taufiq Murtadho, Bi Hong Tiang +2
Entanglement dynamics depend not only on how a quantum system is partitioned, but critically on how interactions across that partition are structured. For a spatial bipartition of…
Third-quantized master equations as a classical Ornstein-Uhlenbeck process
Léonce Dupays
Third quantization is used in open quantum systems to construct a superoperator basis in which quadratic Lindbladians can be turned into a normal form. From it follows the spectral…
Slow approach to adiabaticity in many-body non-Hermitian systems: the Hatano-Nelson Model
Léonce Dupays, Adolfo del Campo, Balázs Dóra
We explore the near adiabatic dynamics in a non-Hermitian quantum many-body system by investigating a finite-time ramp of the imaginary vector potential in the interacting Hatano-N…
Transitionless Quantum Driving of the Tomonaga-Luttinger Liquid
Léonce Dupays, Adolfo del Campo
Shortcuts to adiabaticity (STA) make the fast preparation of many-body states possible, circumventing the limitations of adiabatic strategies. We propose a fast STA protocol for ge…
Exact Dynamics and Shortcuts to Adiabaticity in the Tomonaga-Luttinger Liquid
Léonce Dupays, Balázs Dóra, Adolfo del Campo
Controlling many-body quantum systems is a highly challenging task required to advance quantum technologies. Here, we report progress in controlling gapless many-body quantum syste…
Time-Optimal Quantum Driving by Variational Circuit Learning
Tangyou Huang, Yongcheng Ding, Léonce Dupays +4
The simulation of quantum dynamics on a digital quantum computer with parameterized circuits has widespread applications in fundamental and applied physics and chemistry. In this c…
Exact Delta Kick Cooling, Time-Optimal Control of Scale-Invariant Dynamics, and Shortcuts to Adiabaticity Assisted by Kicks
Léonce Dupays, David C. Spierings, Aephraim M. Steinberg +1
Delta kick cooling (DKC) is used to compress the momentum distribution of ultracold quantum matter. It combines expansion dynamics with the use of kick pulses, designed via classic…
Superadiabatic thermalization of a quantum oscillator by engineered dephasing
L. Dupays, I. L. Egusquiza, A. del Campo +1
Fast nonadiabatic control protocols known as shortcuts to adiabaticity have found a plethora of applications, but their use has been severely limited to speeding up the dynamics of…
