Using polarons for sub-nk quantum nondemolition thermometry in a bose-einstein condensate
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 …

Equilibration time scales in closed many-body quantum systems
TR De Oliveira, C Charalambous… - New Journal of …, 2018 - iopscience.iop.org
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 …

Non-Markovian polaron dynamics in a trapped Bose-Einstein condensate
We study the dynamics of an impurity embedded in a trapped Bose-Einstein condensate, ie,
the Bose polaron problem. This problem is treated by recalling open quantum systems …

Two distinguishable impurities in BEC: squeezing and entanglement of two Bose polarons
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 …

[HTML][HTML] Control of anomalous diffusion of a Bose polaron
We study the diffusive behavior of a Bose polaron immersed in a coherently coupled two-
component Bose-Einstein Condensate (BEC). We assume a uniform, one-dimensional BEC …

[HTML][HTML] Biased-voter model: How persuasive a small group can be?
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 and …
