Dynamic transitions and hysteresis

BK Chakrabarti, M Acharyya - Reviews of Modern Physics, 1999 - APS
When an interacting many-body system, such as a magnet, is driven in time by an external
perturbation, such as a magnetic field, the system cannot respond instantaneously due to …

Scaling of hysteresis dispersion in a model spin system

JM Liu, HLW Chan, CL Choy, CK Ong - Physical Review B, 2001 - APS

Exotic freezing of response in a quantum many-body system

A Das - Physical Review B—Condensed Matter and Materials …, 2010 - APS
We show that when a quantum many-body system is subjected to coherent periodic driving,
the response may exhibit exotic freezing behavior in high driving frequency (ω) regime. In a …
