Ultrafast All-Optical Switching via a Supersolid Phase Transition of Light
J. L. Figueiredo, J. T. Mendonça, H. Terças
We propose ultrafast all-optical switching exploiting the bistability between a spatially uniform photon superfluid and a spontaneously ordered supersolid in a driven-dissipative m…
The role of the exchange-Coulomb potential in two-dimensional electron transport
J. L. Figueiredo, J. T. Mendonça, H. Terças
We develop a quantum kinetic theory of two-dimensional electron gases in which exchange is treated self-consistently at the Hartree-Fock level and enters as a nonlocal, momentum-de…
Photon Bose-Einstein Condensation in Semiconductors: A Quantum Kinetic Theory
José L. Figueiredo, Ross C. Schofield, Ming Fu +4
Photon condensation in semiconductor microcavities is a transformative technique for engineering quantum states of light at room temperature by tailoring strong but incoherent ligh…
Supersolid light in a semiconductor microcavity
J. L. Figueiredo, J. T. Mendonça, H. Terças
Supersolidity - simultaneous superfluid flow and crystalline order - has been realized in quantum atomic systems but remains unexplored in purely photonic platforms operating at we…
Anisotropy-Induced Magnetic Field Generation in Bidimensional Materials
Diogo Simões, Hugo Terças, Jorge Ferreira
We investigate an electromagnetic instability in two-dimensional materials arising from an anisotropy of the Fermi surface, utilizing a kinetic model accounting for the effects of…
Normal modes and shockwaves in cold atoms
Francisco Raposo, Hugo Terças
Numerical methods are developed to simulate the dynamics of atoms in a Magneto-Optic Trap (MOT), based on the fluid description of ultracold gases under laser cooling and magnetic…
Multiplexed quantum repeaters with hot multimode alkali-noble gas memories
Alexandre Barbosa, Hugo Terças, Emmanuel Zambrini Cruzeiro
We propose a non-cryogenic optical quantum memory for noble-gas nuclear spins based on the Atomic Frequency Comb (AFC) protocol. Owing to the hours-long coherence lifetimes of the…
Superdiffusion of vortices in two-component quantum fluids of light
M. Roldão, J. L. Figueiredo, P. Monteiro +2
The quantum diffusion of a vortex in a two-component quantum fluid of light is investigated. In these systems, the Kerr nonlinearity promotes interactions between the photons, disp…
Conductance suppression due to two-stream instability in bilayer graphene
Vasco Pinhão, Pedro Cosme, Hugo Terças
We investigate the electron-hole two-stream instability (or Coulomb drag) in intrinsic bilayer graphene in the hydrodynamic regime, accounting for the effects of temperature, initi…
Towards the detection of ultra-low energetic neutrinos with plasma metamaterials
C. Alfisi, H. Terças
Experiments as IceCube or Super-Kamiokande have been successful in detecting highly energetic neutrinos in the. Neutrinos in the ultra-low energy range ()…
Hydrodynamic electrons in Graphene: a viscous boundary-layer description
Pedro Cosme, João S. Santos, Hugo Terças
In this paper we dwell over the study of the boundary layer problem in a hydrodynamical description of the electrons in gated graphene. It has been verified experimentally that thi…
Roton-Induced Trapping in Strongly Correlated Rydberg Gases
João D. Rodrigues, Luís F. Gonçalves, Hugo Terças +2
Atoms excited into high-lying Rydberg states and under strong dipole-dipole interactions exhibit phenomena associated with highly correlated and complex systems. We perform first p…
Collective dynamics of accelerated atoms
Benedikt Richter, Hugo Terças, Yasser Omar +1
We study the collective dynamics of accelerated atoms interacting with a massless field via an Unruh-deWitt-type interaction. We first derive a general Hamiltonian describing such…
Polytropic equilibrium and normal modes in cold atomic traps
H. Terças, J. T. Mendonça
The compressibility limit of a cold gas confined in a magneto-optical trap due to multiple scattering of light is a long-standing problem. This scattering mechanism induces long-ra…
Plasmon wakefields and dispersive properties of metallic nanostructures
S. Ali, H. Terças, J. T. Mendonça
We investigate the excitation of electrostatic wakefields in metallic nanostructures (nanowires) due to the propagation of a short electron pulse. For that purpose, a dispersive (n…
