Benchmarking the role of particle statistics in Quantum Reservoir Computing
Guillem Llodrà, Christos Charalambous, Gian Luca Giorgi +1
Quantum reservoir computing is a neuro-inspired machine learning approach harnessing the rich dynamics of quantum systems to solve temporal tasks. It has gathered attention for its…
Biased-voter model: how persuasive a small group can be?
Agnieszka Czaplicka, Christos Charalambous, Raul Toral +1
We study the voter model dynamics in the presence of confidence and bias. We assume two types of voters. Unbiased voters whose confidence is indifferent to the state of the voter a…
Quantum dynamics of Bose-polaron in a -dimensional Bose Einstein condensate
M. Miskeen Khan, H. Terças, J. T. Mendonça +4
We study the quantum motion of an impurity atom immersed in a Bose Einstein condensate in arbitrary dimension. The Bogoliubov excitations of the Bose Einstein condensate act as a b…
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…
Heat current control in trapped BEC
Christos Charalambous, Miguel-Angel Garcia-March, Mohammad Mehboudi +1
We investigate the heat transport and the control of heat current among two spatially separated trapped Bose-Einstein Condensates (BEC), each of them at a different temperature. To…
Using polarons for sub-nK quantum non-demolition thermometry in a Bose-Einstein condensate
Mohammad Mehboudi, Aniello Lampo, Christos Charalambous +3
We introduce a novel minimally-disturbing method for sub-nK thermometry in a Bose-Einstein condensate (BEC). Our technique is based on the Bose-polaron model; namely, an impurity e…
Two distinguishable impurities in BEC: squeezing and entanglement of two Bose polarons
C. Charalambous, M. A. Garcia-March, A. Lampo +2
We study entanglement and squeezing of two uncoupled impurities immersed in a Bose-Einstein condensate. We treat them as two quantum Brownian particles interacting with a bath comp…
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…
Transient subdiffusion from an Ising environment
G. Muñoz-Gil, C. Charalambous, M. A. García-March +4
We introduce a model, in which a particle performs a continuous time random walk (CTRW) coupled to an environment with Ising dynamics. The particle shows locally varying diffusivit…
Equilibration time scales in closed many-body quantum systems
Thiago R. de Oliveira, Christos Charalambous, Daniel Jonathan +2
We show that the physical mechanism for the equilibration of closed quantum systems is dephasing, and identify the energy scales that determine the equilibration timescale of a giv…
Nonergodic subdiffusion from transient interactions with heterogeneous partners
C. Charalambous, G. Muñoz-Gil, A. Celi +4
Spatiotemporal disorder has been recently associated to the occurrence of anomalous nonergodic diffusion of molecular components in biological systems, but the underlying microscop…
