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…
Commensurate supersolids and re-entrant transitions in an extended Bose-Hubbard ladder
Ashwath N Madhusudan, Gopal Chandra Santra, Inderpreet Kaur +2
We investigate the ground state phases of an extended Bose-Hubbard ladder of unit filling via the density-matrix-renormalization-group method and, in particular, the effect of rung…
Properties of Krylov state complexity in qubit dynamics
Siddharth Seetharaman, Chetanya Singh, Rejish Nath
We analyze the properties of Krylov state complexity in qubit dynamics, considering a single qubit and a qubit pair. A geometrical picture of the Krylov complexity is discussed for…
Rydberg superatoms: An artificial quantum system for quantum information processing and quantum optics
Xiao-Qiang Shao, Shi-Lei Su, Lin Li +3
Dense atom ensembles with Rydberg excitations display intriguing collective effects mediated by their strong, long-range dipole-dipole interactions. These collective effects, often…
Path Integral Monte Carlo Study of a Doubly-Dipolar Bose Gas
Ratheejit Ghosh, Matteo Ciardi, Rejish Nath +1
By combining first-principles path integral Monte Carlo methods and mean-field techniques, we explore the properties of cylindrically trapped doubly-dipolar Bose gases. We first ve…
