Quantum memory at an eigenstate phase transition in a weakly chaotic model
M. R. Lambert, Shan-Wen Tsai, Shane P. Kelly
We study a fully connected quantum spin model resonantly coupled to a small environment of non-interacting spins, and investigate how initial state properties are remembered at lon…
On the early-time behavior of quantum subharmonic generation
Yunjin Choi, Boerge Hemmerling, Shan-Wen Tsai +1
A few years ago Avetissian {\it et al.} \cite{Avetissian2014,Avetissian2015} discovered that the exponential growth rate of the stimulated annihilation photons from a singlet posit…
Thermalization and its Breakdown for a Large Nonlinear Spin
Shane P. Kelly, Eddy Timmermans, S. -W. Tsai
By developing a semi-classical analysis based on the Eigenstate Thermalization Hypothesis, we determine the long time behavior of a large spin evolving with a nonlinear Hamiltonian…
Detecting Macroscopic Indefiniteness of Cat States in Bosonic Interferometers
Shane P. Kelly, Eddy Timmermans, S. W. Tsai
The paradigm of Schrödinger's cat illustrates how quantum states preclude the assignment of definite properties to a macroscopic object (realism). In this work we develop a method…
