We study anisotropies of the helicity modulus, excitation spectrum, sound velocity, and angle-
resolved luminescence spectrum in a two-dimensional system of interacting excitons in a …

We investigate a system of two-atomic species in mixed dimensions, in which one species is
spread in a three-dimensional space and the other species is confined in two parallel layers …

We examine the competition between the charge-density wave (CDW) instability and the
excitonic condensate (EC) in spatially separated layers of electrons and holes. The CDW …

An exciton condensate is a vast playground in studying a number of symmetries that are of
high interest in the recent developments in topological condensed matter physics. In double …

We investigate a system of two-atomic species in mixed dimensions, in which one species is
spread in a three-dimensional space and the other species is confined in two parallel layers …

Excitonic systems are challenging to deal with both theoretically and experimentally but in
return, they offer a very rich physics and exotic features. We will investigate their properties …

It is shown that exciton condensates exhibit an incredible richness in the role that
fundamental symmetries play whether manifest or broken. We investigate the appearance of …
