Quarkonia Production and Dissociation in a Langevin Approach
Proceedings, 2019 We aim to describe the process of dissociation and recombination of quarkonia in the quark-gluon plasma. Therefore we developed a model which allows to observe the time evolution of a system with various numbers of charm-anticharm-quark pairs at ...

Hydrodynamic transport functions from quantum kinetic theory [PDF]
, 2000 Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) effective action we show how to compute from first principles the shear and

On dynamical localization corrections to band transport [PDF]
, 2019 Bloch-Boltzmann transport theory fails to describe the carrier diffusion in current crystalline organic semiconductors, where the presence of large-amplitude thermal molecular motions causes substantial dynamical disorder.

Quasiclassical theory of charge transport in disordered interacting electron systems [PDF]
, 2003 We consider the corrections to the Boltzmann theory of electrical transport arising from the Coulomb interaction in disordered conductors. In this article the theory is formulated in terms of quasiclassical Green's functions.

Anderson Localization of Matter Waves in 3D Anisotropic Disordered Potentials [PDF]
, 2014 Using a cutoff-free formulation of the coherent transport theory, we show that the interference terms at the origin of localization strongly affect the transport anisotropy.

The High-Density Symmetry Energy in Heavy-Ion Collisions and Compact Stars
Universe, 2018 High-density nuclear symmetry energy is of crucial importance in astrophysics. Information on such energy has been obtained from mass–radius determinations of neutron stars (NSs), and in the future NS mergers will increasingly contribute.

Transport Theory beyond Binary Collisions
, 2004 Using the Schwinger-Keldysh technique, we derive the transport equations for a system of quantum scalar fields. We first discuss the general structure of the equations and then their collision terms.

Theory of carrier transport in bilayer graphene [PDF]
, 2009 We develop a theory for density, disorder, and temperature dependent electrical conductivity of bilayer graphene in the presence of long-range charged impurity scattering as well as an additional short-range disorder of independent origin, establishing ...
