Multiple abrupt phase transitions in urban transport congestion
Aniello Lampo, Javier Borge-Holthoefer, Sergio Gómez +1
During the last decades, the study of cities has been transformed by new approaches combining engineering and complexity sciences. Network theory is playing a central role, facilit…
Decoherence of spin registers revisited
Jan Tuziemski, Aniello Lampo, Maciej Lewenstein +1
We revisit decoherence process of a qubit register interacting with a thermal bosonic bath. We generalize the previous studies by considering not only the register's behavior but a…
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…
