Topological charges and parity selection at Floquet quasienergy degeneracies
Sigmund Kohler, David Guéry-Odelin
The quasienergy spectrum of a strongly driven two-level system as a function of the driving parameters exhibits conical intersections, which are enabled by hidden time-nonlocal sym…
Cooperative control of dissipative qubits: steering along the fastest dissipative contraction
Robert Weiß, Sandro Wimberger, David Guéry-Odelin
In the control of dissipative quantum systems, the slow relaxation modes usually set the ultimate manipulation timescale. We show that this bottleneck can be bypassed when dissipat…
Fate of Boltzmann's breathers: kinetic theory perspective
P. Maynar, M. I. García de Soria, D. Guéry-Odelin +1
The dynamics of a system composed of elastic hard particles confined by an isotropic harmonic potential are studied. In the low-density limit, the Boltzmann equation provides an ex…
Optimal synchronisation to a limit cycle
C. Ríos-Monje, C. A. Plata, D. Guéry-Odelin +1
In the absence of external forcing, all trajectories on the phase plane of the van der Pol oscillator tend to a closed, periodic, trajectory -- the limit cycle -- after infinite ti…
Introduction to Theoretical and Experimental aspects of Quantum Optimal Control

Quantum optimal control is a set of methods for designing time-varying electromagnetic fields to perform operations in quantum technologies. This tutorial paper introduces the basi…
Emergence of a tunable crystalline order in a Floquet-Bloch system from a parametric instability
Nathan Dupont, Lucas Gabardos, Floriane Arrouas +6
Parametric instabilities in interacting systems can lead to the appearance of new structures or patterns. In quantum gases, two-body interactions are responsible for a variety of i…
