Nonperturbative dynamical decoupling with random control
(Nature Publishing Group, 2014-08-29)
Parametric fluctuations or stochastic signals are introduced into the rectangular pulse sequence to investigate the feasibility of random dynamical decoupling. In a large parameter region, we find that the out-of-order ...
Symmetry restoration and quantumness reestablishment
(Nature Publishing Group, 2014-09-18)
A realistic quantum many-body system, characterized by a generic microscopic Hamiltonian, is accessible only through approximation methods. The mean field theories, as the simplest practices of approximation methods, ...
