Dissipative transverse-field Ising model: steady-state correlations and spin squeezing
Tony E. Lee, Ching-Kit Chan
We study the transverse-field Ising model with infinite-range coupling and spontaneous emission on every site. We find that there is spin squeezing in steady state due to the prese…
Quantum synchronization of quantum van der Pol oscillators with trapped ions
Tony E. Lee, H. R. Sadeghpour
Van der Pol oscillators are prototypical self-sustaining oscillators which have been used to model nonlinear processes in biological and other classical processes. In this work, we…
Spatial correlations of one dimensional driven-dissipative systems of Rydberg atoms
Anzi Hu, Tony E. Lee, Charles W. Clark
We consider a one-dimensional lattice of atoms with laser excitation to a Rydberg state and spontaneous emission. The atoms are coupled due to the dipole-dipole interaction of the…
Unconventional magnetism via optical pumping of interacting spin systems
Tony E. Lee, Sarang Gopalakrishnan, Mikhail D. Lukin
We consider strongly interacting systems of effective spins, subject to dissipative spin-flip processes associated with optical pumping. We predict the existence of novel magnetic…
