Engineering the Bogoliubov Modes through Geometry and Interaction: From Collective Edge Modes to Flat-band Excitations
Maryam Darvishi, Fatemeh Pouresmaeeli, Saeed H. Abedinpour
We propose a procedure to engineer solid-state lattice models with superlattices of interaction-coupled Bose-Einstein condensates. We show that the dynamical equation for the excit…

Density and pseudo-spin rotons in a bilayer of soft-core bosons
Fatemeh Pouresmaeeli, Saeed H. Abedinpour, B. Tanatar
We study the dynamics of a bilayer system of bosons with repulsive soft-core Rydberg-dressed interactions within the mean-field Bogoliubov-de Gennes approximation. We find roton mi…
