Quantum Random Number Generators : Benchmarking and Challenges
David Cirauqui, Miguel Ángel García-March, Guillem Guigó Corominas +5
We discuss the current state of the art of Quantum Random Number Generators (QRNG) and their possible applications in the search for quantum advantages. To this aim, we first discu…
Control of anomalous diffusion of a Bose polaron
Christos Charalambous, Miguel Ángel García-March, Gorka Muñoz-Gil +2
We study the diffusive behavior of a Bose polaron immersed in a coherently coupled two-component Bose-Einstein Condensate (BEC). Polaron superdiffuses if it couples in the same man…
Non-Markovian polaron dynamics in a trapped Bose-Einstein condensate
Aniello Lampo, Christos Charalambous, Miguel Ángel García-March +1
We study the dynamics of an impurity embedded in a trapped Bose-Einstein condensate (Bose polaron), by recalling the quantum Brownian motion model. It is crucial that the model con…
Photonic Nambu-Goldstone bosons
Miguel Ángel García-March, Ángel Paredes, Mario Zacarés +2
We study numerically the spatial dynamics of light in periodic square lattices in the presence of a Kerr term, emphasizing the peculiarities stemming from the nonlinearity. We find…
Bose polaron as an instance of quantum Brownian motion
Aniello Lampo, Soon Hoe Lim, Miguel Ángel García-March +1
We study the dynamics of a quantum impurity immersed in a Bose-Einstein condensate as an open quantum system in the framework of the quantum Brownian motion model. We derive a gene…
Non-Equilibrium Thermodynamics of Harmonically Trapped Bosons
Miguel Ángel García-March, Thomás Fogarty, Steve Campbell +2
We apply the framework of non-equilibrium quantum thermodynamics to the physics of quenched small-sized bosonic quantum gases in a one-dimensional harmonic trap. We show that dynam…
Quantum simulation of conductivity plateaux and fractional quantum Hall effect using ultracold atoms
Nuria Barberán, Daniel Dagnino, Miguel Angel García-March +3
We analyze the role of impurities in the fractional quantum Hall effect using a highly controllable system of ultracold atoms. We investigate the mechanism responsible for the form…
Quenching small quantum gases: Genesis of the orthogonality catastrophe
Steve Campbell, Miguel Ángel García-March, Thomás Fogarty +1
We study the dynamics of two strongly interacting bosons with an additional impurity atom trapped in a harmonic potential. Using exact numerical diagonalization we are able to full…
Symmetry, winding number and topological charge of vortex solitons in discrete-symmetry media
Miguel-Ángel García-March, Albert Ferrando, Mario Zacarés +2
We determine the functional behavior near the discrete rotational symmetry axis of discrete vortices of the nonlinear Schrödinger equation. We show that these solutions present a c…
Supersolid behavior of nonlinear light
Albert Ferrando, Miguel Ángel García-March, Mario Zacarés
We present a formal demonstration that light can simultaneously exhibit a superfluid behavior and spatial long-range order when propagating in a photonic crystal with self-focussin…
