Negative diffusivity of excitons in electron-hole plasmas
H. Terças, V. N. Mantsevich
We develop a minimal hydrodynamic framework to describe exciton transport in the presence of an electron hole plasma in 2D semiconductors. Treating excitons, electrons, and holes a…
Spontaneous Symmetry Breaking of Time-Reversal-Symmetry and Time-Crystal States in Chiral Atomic Systems
Mário G. Silveirinha, Hugo Terças, Mauro Antezza
We present a theoretical study of the interaction between an atom characterized by a degenerate ground state and a reciprocal environment, such as a semiconductor nanoparticle, wit…
Sub-nK thermometry of an interacting -dimensional homogeneous Bose gas
Muhammad Miskeen Khan, Mohammad Mehboudi, Hugo Tercas +2
We propose experimentally feasible means for non-destructive thermometry of homogeneous Bose Einstein condensates in different spatial dimensions (). Our impurity ba…
Sideband ground-state cooling of graphene with Rydberg atoms via vacuum forces
M. Miskeen Khan, S. Ribeiro, J. T. Mendonça +1
We present a scheme leading to ground-state cooling of the fundamental out-of-plane (flexural) mode of a suspended graphene sheet. Our proposal exploits the coupling between a driv…
Emergence of Spatial Order in Highly Interacting Rydberg Gases
João D. Rodrigues, Hugo Terças, Luis F. Gonçalves +2
We describe the emergence of strong spatial correlations, akin to liquid-like behavior and crystallization effects, in low (one and two) dimensional gases of cold Rydberg atoms. Th…
Cooling and entanglement of multimode graphene resonators via vacuum fluctuations
Sofia Ribeiro, Hugo Terças
Sympathetic laser cooling of a single mode graphene membrane coupled to an atomic cloud interacting via Casimir-Polder forces has been recently proposed. Here, we extend this study…
