Hidden time-reversal in driven XXZ spin chains: exact solutions and new dissipative phase transitions
Mingxing Yao, Andrew Lingenfelter, Ron Belyansky +2
We show that several models of interacting XXZ spin chains subject to boundary driving and dissipation possess a subtle kind of time-reversal symmetry, making their steady states e…
Unconditional Fock state generation using arbitrarily weak photonic nonlinearities
Andrew Lingenfelter, David Roberts, A. A. Clerk
We present a new mechanism that harnesses extremely weak Kerr-type nonlinearities in a single driven cavity to deterministically generate single photon Fock states, and more genera…
Hidden time-reversal symmetry, quantum detailed balance and exact solutions of driven-dissipative quantum systems
David Roberts, Andrew Lingenfelter, Aashish Clerk
Driven-dissipative quantum systems generically do not satisfy simple notions of detailed balance based on the time symmetry of correlation functions. We show that such systems can…
Driven-dissipative quantum Kerr resonators: new exact solutions, photon blockade and quantum bistability
David Roberts, Aashish Clerk
We present a new approach for deriving exact, closed-form solutions for the steady state of a wide class of driven-dissipative nonlinear resonators that is distinct from more commo…
Noise amplification at spin-glass bottlenecks of quantum annealing: a solvable model
David Roberts, Lukasz Cincio, Avadh Saxena +2
To gain better insight into the complexity theory of quantum annealing, we propose and solve a class of spin systems which contain bottlenecks of the kind expected to dominate the…
Casimir Friction I: Friction of a vacuum on a spinning dielectric
Yves Pomeau, David C. Roberts
We introduce the concept of Casimir friction, i.e. friction due to quantum fluctuations. In this first article we describe the calculation of a constant torque, arising from the sc…
Limitations of light delay and storage times in EIT experiments with condensates
D. C. Roberts, T. Gasenzer, K. Burnett
We investigate the limitations arising from atomic collisions on the storage and delay times of probe pulses in EIT experiments. We find that the atomic collisions can be described…
Exciting Relative Number Squeezed Particles from Condensates Using Stimulated Light Scattering
D. C. Roberts, T. Gasenzer, K. Burnett
We investigate the relative particle number squeezing produced in the excited states of a weakly interacting condensate at zero temperature by stimulated light scattering using a p…
Entanglement between photons and atoms coupled out from a Bose-Einstein-Condensate
T. Gasenzer, D. C. Roberts, K. Burnett
We study the limitations to the relative number squeezing between photons and atoms coupled out from a homogeneous Bose-Einstein-Condensate. We consider the coupling between the tr…
