Quantum kinetic theory for spin transport of quarks with background chromo-electromagnetic fields [PDF]
We derive the quantum kinetic equations for massive and massless quarks coupled with the background chromo-electromagnetic fields from the Wigner-function approach with the n expansion and effective power-counting scheme.

Quantum theory of superfluorescence based on two-point correlation functions [PDF]
Irradiation of a medium by short intense pulses from x-ray / XUV free electron lasers can result in saturated photoionization of inner electronic shells. As a result an inversion of populations between core levels appears.

Correlation function of modular Hamiltonians [PDF]
We investigate varies correlation functions of modular Hamiltonians defined with respect to spatial regions in quantum field theory. These correlation functions are divergent in general.

Kinetic theory with Berry curvature from quantum field theories [PDF]
A kinetic theory can be modified to incorporate triangle anomalies and the chiral magnetic effect by taking into account the Berry curvature flux through the Fermi surface.

Subdynamics of relevant observables: a field theoretical approach [PDF]
An approach to the description of subdynamics inside non-relativistic quantum field theory is presented, in which the notions of relevant observable, time scale and complete positivity of the time evolution are stressed. A scattering theory derivation of

Cosmological perturbations from stochastic gravity [PDF]
In inflationary cosmological models driven by an inflaton field the origin of the primordial inhomogeneities which are responsible for large scale structure formation are the quantum fluctuations of the inflaton field.

Quantum kinetic theory of metal clusters in an intense electromagnetic field
A quantum kinetic theory for weakly inhomogeneous charged particle systems is derived within the framework of nonequilibrium Green's functions. The results are of relevance for valence electrons of metal clusters as well as for confined Coulomb systems ...

Low energy effective theory of Fermi surface coupled with U(1) gauge field in 2+1 dimensions [PDF]
We study the low energy effective theory for a non-Fermi liquid state in 2+1 dimensions, where a transverse U(1) gauge field is coupled with a patch of Fermi surface with N flavors of fermion in the large N limit.

Positivity, low twist dominance and CSDR for CFTs
We consider a crossing symmetric dispersion relation (CSDR) for CFT four point correlation with identical scalar operators, which is manifestly symmetric under the cross-ratios $u,v$ interchange.
