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…
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…
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…
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…
