Quantum phase transitions of tri-layer excitons in atomically thin heterostructures
Yevgeny Slobodkin, Yotam Mazuz-Harpaz, Sivan Refaely-Abramson +3
We determine the zero temeperature phase diagram of excitons in the symmetric transition-metal dichalcogenide tri-layer heterosctructure WSe2/MoSe2/WSe2. First principle calculatio…
Attractive dipolar coupling between stacked exciton fluids
Colin Hubert, Yifat Baruchi, Yotam Mazuz-Harpaz +7
The interaction between aligned dipoles is long-ranged and highly anisotropic: it changes from repulsive to attractive depending on the relative positions of the dipoles. We report…
Dynamical formation and interaction-induced stabilization of dark condensates of dipolar excitons
Yotam Mazuz-Harpaz, Maxim Khodas, Ronen Rapaport
The formation of a dense Bose-Einstein condensate in dark spin states of two-dimensional dipolar excitons is shown to be driven by a dynamical transition to the long-lived dark sta…
Strongly interacting dipolar-polaritons
Itamar Rosenberg, Dror Liran, Yotam Mazuz-Harpaz +3
Exciton-polaritons are mutually interacting quantum hybridizations of confined photons and electronic excitations. Here we demonstrate a system of optically guided, electrically po…
Condensation to a strongly correlated dark fluid of two dimensional dipolar excitons
Yotam Mazuz-Harpaz, Kobi Cohen, Ronen Rapaport
Recently we reported on the condensation of cold, electrostatically trapped dipolar excitons in GaAs bilayer heterostructure into a new, dense and dark collective phase. Here we an…
Radiative lifetimes of dipolar excitons in double quantum-wells
Yotam Mazuz-Harpaz, Kobi Cohen, Boris Laikhtman +3
Spatially indirect excitons in semiconducting double quantum wells have been shown to exhibit rich collective many-body behavior that result from the nature of the extended dipole-…
