Dynamical Scaling Laws of Out-of-Time-Ordered Correlators
Bo-Bo Wei, Gaoyong Sun, Myung-Joong Hwang
The out-of-time-ordered correlator (OTOC) is central to the understanding of information scrambling in quantum many-body systems. In this work, we show that the OTOC in a quantum m…
Universality in the Decay and Revival of Loschmidt Echoes
Myung-Joong Hwang, Bo-Bo Wei, Susana F. Huelga +1
A critically enhanced decay of the Loschmidt echo is characteristic of sudden quench dynamics near a quantum phase transition. Here, we demonstrate that the decay and revival of th…
Quantum Statistical Enhancement of the Collective Performance of Multiple Bosonic Engines
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +2
We consider an ensemble of indistinguishable quantum machines and show that quantum statistical effects can give rise to a genuine quantum enhancement of the collective thermodynam…
Ultrastrong coupling regime of non-dipolar light-matter interactions
Simone Felicetti, Myung-Joong Hwang, Alexandre Le Boité
We present a circuit-QED scheme which allows to reach the ultrastrong coupling regime of a nondipolar interaction between a single qubit and a quantum resonator. We show that the s…
Dissipative Phase Transition in the Open Quantum Rabi Model
Myung-Joong Hwang, Peter Rabl, Martin B. Plenio
We demonstrate that the open quantum Rabi model (QRM) exhibits a second-order dissipative phase transition (DPT) and propose a method to observe this transition with trapped ions.…
Recurrent delocalization and quasi-equilibration of photons in coupled circuit QED systems
Myung-Joong Hwang, M. S. Kim, Mahn-Soo Choi
We explore the photon population dynamics in two coupled circuit QED systems. For a sufficiently weak inter-cavity photon hopping, as the photon-cavity coupling increases, the dyna…
