Quantum state localization in dipole-dipole interacting disordered networks
Pritam Chattopadhyay, Saikat Sur, Avijit Misra +3
We study the localization of excitations in positionally disordered spin or atom networks coupled via the realistic resonant dipole-dipole interaction (RDDI), which does not confor…

Shaping Cold Atom Clouds with a Vortex Beam
Arianna Bertoluzza, Sonja Lorenz, Paul Hampp +5
We introduce a method for shaping a cold atom cloud using a vortex laser beam with a polarization singularity at its center, which creates a point of vanishing intensity. Exploitin…

Sensing multiatom networks in cavities via photon-induced excitation resonance
Pritam Chattopadhyay, Avijit Misra, Saikat Sur +2
We explore the distribution in space and time of a single-photon excitation shared by a network of dipole-dipole interacting atoms that are also coupled to a common photonic field…
