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…
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…
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…
Time scaling and quantum speed limit in non-Hermitian Hamiltonians
F. Impens, F. M. D'Angelis, F. A. Pinheiro +1
We report on a time scaling technique to enhance the performances of quantum protocols in non-Hermitian systems. The considered time scaling involves no extra-couplings and yields…
Fast and robust quantum state transfer in a topological Su-Schrieffer-Heeger chain with Next-to-Nearest-Neighbour interactions
Felippo M. D'Angelis, Felipe A. Pinheiro, David Guéry-Odelin +2
We suggest a method for fast and robust quantum-state transfer in a Su-Schrieffer-Heeger (SSH) chain, which exploits the use of next-to-nearest-neighbour (NNN) interactions. The pr…
Decoherence and collective effects in critical media
F. M. D Angelis, F. A. Pinheiro, F. Impens
We investigate the influence of critical phenomena on two distinct physical processes: the center-of-mass decoherence of a single emitter, and the collective radiation of two emitt…
Microscopic dynamical Casimir effect
Reinaldo de Melo e Souza, François Impens, Paulo A. Maia Neto
We consider an atom in its ground state undergoing a non-relativistic oscillation in free space. The interaction with the electromagnetic quantum vacuum leads to two effects to lea…
Driving quantized vortices with quantum vacuum fluctuations
François Impens, Ana M. Contreras-Reyes, Paulo A. Maia Neto +4
We propose to use a rotating corrugated material plate in order to stir, through the Casimir-Polder interaction, quantized vortices in an harmonically trapped Bose-Einstein condens…
Classical phase-space approach for coherent matter waves
François Impens, David Guéry-Odelin
We investigate a classical phase-space approach of matter-wave propagation based on the Truncated Wigner Equation (TWE). We show that such description is suitable for ideal matter…
Quality factor of a matter-wave beam
François Impens
Imperfections in dilute atomic beams propagating in the paraxial regime and in potentials of cylindrical symmetry have been characterized experimentally through the measurement of…
Matter-wave cavity gravimeter
F. Impens, P. Bouyer, Ch. J. Bordé
We propose a gravimeter based on a matter-wave resonant cavity loaded with a Bose-Einstein condensate and closed with a sequence of periodic Raman pulses. The gravimeter sensitivit…
