Improved diffusive approximation of Markov jump processes close to equilibrium
David Roberts, Trevor McCourt, Geremia Massarelli +2
Diffusive approximations of Markov jump processes often fail to accurately capture large fluctuations. This is confounding, as the rare events triggered by these large fluctuations…
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…
