Fast quantum-state transfer in Su-Schrieffer-Heeger chains beyond the noninteracting regime
François Impens, David Guéry-Odelin
Shortcuts to adiabaticity have made topological edge-state transfer fast in the single-particle regime, but their extension to interacting systems is obstructed by nonlinear phase…
Dynamical Casimir photons from rotation of a nonspherical particle
Guilherme C. Matos, Lucas Bianchi, Jeremy N. Munday +3
We consider a non-spherical neutral particle spinning in free space and interacting with the electromagnetic quantum vacuum. When the rotation axis is orthogonal to the particle sy…
Quantum Geometric Limits for Non-Abelian Holonomies
François Impens, David Guéry-Odelin
Stokes' theorem turns Abelian Berry phases into curvature fluxes, whereas path ordering precludes such a simple formula for non-Abelian holonomies. We show that a quantitative form…
Localization Landscape in Non-Hermitian and Floquet quantum systems
David Guéry-Odelin, François Impens
We propose a generalization of the Filoche--Mayboroda localization landscape that extends the theory well beyond the static, elliptic and Hermitian settings while preserving its ge…
Approaching the Quantum Speed Limit in Quantum Gates with Geometric Control
F. Impens, D. Guéry-Odelin
We present a geometric optimization method for implementing quantum gates by optimally controlling the Hamiltonian parameters, with the goal of approaching the Mandelstam-Tamm Quan…
Optimal control over the full counting statistics in a non-adiabatic pump
François Impens, Felippo M. D'Angelis, David Guéry-Odelin +2
We introduce a systematic procedure based on optimal control theory to address the full counting statistics of particle transport in a stochastic system. Our approach enhances the…
