We had been hoping to be able to hold the conference on the originally scheduled period in October 2021 but given the pandemic situation we have decided to postpone the conference period to October 2022.

In recent years, experiments using cold atoms in Rydberg states have emerged as a powerful platform for the quantum simulation of condensed matter Hamiltonians with extended-range interactions (ERI). This perspective for experimental realization has led to strong cross-fertilization between atomic and condensed matter physics, with considerable theoretical work being dedicated to the study of ERI Hamiltonians. As a result, several interesting equilibrium and out-of-equilibrium scenarios have been discovered in this kind of system.

I will present my numerical results for two classes of ERI Hamiltonians: namely, i) the determination [1] of the phase diagram of the Fendley-Sengupta-Sachdev model (recently realized via quantum simulation in Rydberg atom experiments) in the so-called doubly-blockaded regime, where the critical behavior of the system is still not fully understood, and ii) the demonstration of a phase transition between two supersolid states in an extended Bose-Hubbard model, whose interactions are of interest for experiments with atoms in Rydberg-dressed states.
