Fluctuation-Induced Supersolidity at the Superfluid-Solid Interface
Baptiste Coquinot, Ragheed Alhyder, Alberto Cappellaro +1
Supersolidity, combining superfluid and crystalline orders, has been realized in dipolar Bose-Einstein condensates by tuning interatomic interactions. Here we show that supersolidi…

Phenomenological model of decaying Bose polarons
Ragheed Alhyder, Georg M. Bruun, Thomas Pohl +2
Cold atom experiments show that a mobile impurity particle immersed in a Bose-Einstein condensate forms a well-defined quasiparticle (Bose polaron) for weak to moderate impurity-bo…

Quantum transport in the presence of a chiral molecular potential
Ragheed Alhyder, Mikhail Lemeshko, Alberto Cappellaro
We investigate quantum transport in a two-dimensional electron system coupled to a chiral molecular potential, demonstrating how molecular chirality and orientation affect charge a…
