Bloch-sphere rotations in driven double-well for ultracold atoms
Michele Modugno, Marco Fattori, Giulio Pettini
We show that, by using suitable protocols for a non-interacting condensate in a driven double-well, one can achieve controlled rotations about arbitrary axes in the equatorial plan…
Self-sustained Josephson dynamics and self-trapping in supersolids
Aitor Alaña, Michele Modugno, Pablo Capuzzi +1
We explore the self-sustained Josephson junction dynamics in dipolar supersolids, predicting the possibility of self-trapping alongside the experimentally observed Josephson oscill…
Computing Floquet quasienergies in finite and extended systems: Role of electromagnetic and quantum-geometric gauges
Álvaro R. Puente-Uriona, Michele Modugno, Ivo Souza +1
We present an approach to compute the Floquet quasienergy spectrum of time-periodic systems. The method allows to characterize the light-matter interaction in finite and extended s…
Phase-induced vortex pinning in rotating supersolid dipolar systems
Aitor Alaña, Michele Modugno, Pablo Capuzzi +1
We analyze the pinning of vortices for a stationary rotating dipolar supersolid along the low-density paths between droplets as a function of the rotation frequency. We restrict ou…
