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…
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…
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…
New insight into EM radiation from spinning dust and its influence on the Cosmic Microwave Background
Ariel Guerreiro, José Tito Mendonça, Robert Bingham
Dust is ubiquitous in the Universe and its influence on the observed Electromagnetic (EM) radiation needs to be correctly addressed. In recent years it became clear that scattering…
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…
Collisional Effects, Ion-Acoustic Waves and Neutrino Oscillations
Fernando Haas, Kellen Alves Pascoal, José Tito Mendonça
We analyze the role of collisional effects on the coupling between ion-acoustic waves and neutrino flavor oscillations, discussing its relevance for plasma instabilities in extreme…
Orbital angular momentum of a -pulse emission by dense relativistic cold electron beam
J. A. Arteaga, A. Serbeto, J. T. Mendonça +2
Using a quantum fluid model, a set of three paraxial coupled equations to describe the FEL instability is derived. These equations are solved numerically considering Laguerre-Gauss…
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…
Detecting orbital angular momentum in radio signals
H. Then, B. Thidé, J. T. Mendonça +5
Electromagnetic waves with an azimuthal phase shift are known to have a well defined orbital angular momentum. Different methods that allow for the detection of the angular momentu…
