Theory of two-component superfluidity of microcavity polaritons
A. Nafis Arafat, Oleg L. Berman, Godfrey Gumbs +1
We develop a microscopic mean-field theory describing the coexistence of Bose-Einstein condensates of upper and lower polaritons (UP/LP) in a semiconductor microcavity. Incorporati…

Superfluidity of indirect momentum space dark dipolar excitons in a double layer with massive anisotropic tilted semi-Dirac bands
A. Nafis Arafat, Oleg L. Berman, Godfrey Gumbs
We have theoretically investigated the spin- and valley-dependent superfluidity properties of indirect momentum space dark dipolar excitons in double layers with massive anisotropi…

Stress control in non-ideal topological Maxwell lattices via geometry
Harry Liu, Siddhartha Sarkar, A. Nafis Arafat +3
Topological mechanical metamaterials have demonstrated exotic and robust mechanical properties which led to promising engineering applications. One of such properties is the focusi…
