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…
