Dynamical phase transition in generalized Dicke model with strongly interacting trapped Rydberg ions
Manish Chaudhary, Rejish Nath, Weibin Li
We study dynamical phase transitions in the generalized dissipative Dicke model in an array of trapped Rydberg ions, where their density-density interactions compete with the colle…
Quantum dynamics of spin-J particles in static and rotating magnetic fields: Entanglement resonances and kinks
Nargis Sultana, Siddharth Seetharaman, Rejish Nath
We examine the quantum dynamics of both a single spin-J particle and a pair of spin-J particles in the presence of static and rotating magnetic fields, which can be important for q…
Spin Phonon Relaxation Dynamics from a Conical Intersection of Trapped Rydberg Ions
Manish Chaudhary, Rejish Nath, Weibin Li
Non-adiabatic processes near conical intersections are rooted in the stronger coupling between electronic and nuclear degrees of freedom. Using a system of two trapped Rydberg ions…
