Is the finite temperature effective potential, effective for dynamics?
Nathan Herring, Shuyang Cao, Daniel Boyanovsky
We study the applicability of the finite temperature effective potential in the equation of motion of a homogeneous "misaligned" scalar condensate , and find important caveats t…
Condensate decay in a radiation dominated cosmology
Shuyang Cao, Daniel Boyanovsky
We study the decay of a homogeneous condensate of a massive scalar field of mass \emph{m} into massless fields in thermal equilibrium in a radiation dominated cosmology. The model…
Field mixing in a thermal medium: A quantum master equation approach
Shuyang Cao
We studied the nonequilibrium dynamics of the indirect mixing of two (pseudo-)scalar fields induced by their couplings to common decay channels in a medium. The effective non-Marko…
Is the effective potential, effective for dynamics?
Nathan Herring, Shuyang Cao, Daniel Boyanovsky
We critically examine the applicability of the effective potential within dynamical situations and find, in short, that the answer is negative. An important caveat of the use of an…
Effective field theory of particle mixing
Shuyang Cao, Daniel Boyanovsky
We introduce an effective field theory to study \emph{indirect} mixing of two fields induced by their couplings to a common decay channel in a medium. The extension of the method o…
Chern Simons condensate from misaligned axions
Shuyang Cao, Daniel Boyanovsky
We obtain the non-equilibrium condensate of the Chern Simons density induced by a misaligned homogeneous coherent axion field in linear response. The Chern-Simons dynamical suscept…
Dynamics of axion-neutral pseudoscalar mixing
Shuyang Cao, Wenjie Huang, Daniel Boyanovsky
Axions mix with neutral pions after the QCD phase transition through their common coupling to the radiation bath via a Chern-Simons term, as a consequence of the anomaly. Th…
Non-equilibrium dynamics of Axion-like particles: the quantum master equation
Shuyang Cao, Daniel Boyanovsky
We study the non-equilibrium dynamics of Axion-like particles (ALP) coupled to Standard Model degrees of freedom in thermal equilibrium. The Quantum Master Equation (QME) for the (…
Brownian Axion-like particles
Shuyang Cao, Daniel Boyanovsky
We study the non-equilibrium dynamics of a pseudoscalar axion-like particle (ALP) weakly coupled to degrees of freedom in thermal equilibrium by obtaining its reduced density matri…
Extraction and identification of noise patterns for ultracold atoms in an optical lattice
Shuyang Cao, Pengju Tang, Xinxin Guo +3
To extract useful information about quantum effects in cold atom experiments, one central task is to identify the intrinsic quantum fluctuation from extrinsic system noises of vari…
