Strongly Coupled Soft Functions
Bruno Scheihing-Hitschfeld, Zhiquan Sun
The renormalization of operators built out of Wilson lines that meet at an angle (cusp) involve what is known as the cusp anomalous dimension, a universal object appearing in many…
Quantum theory of elastic strings and the thermal conductivity of glasses
Fernando Lund, Bruno Scheihing-Hitschfeld
We study the thermal conductivity of amorphous solids by constructing a continuum model whose degrees of freedom are propagating vibrational modes (phonons) and extended Volterra d…
Adiabatic hydrodynamization and quasinormal modes of nonthermal attractors
Matisse De Lescluze, Michal P. Heller, Aleksas Mazeliauskas +2
Nonthermal attractors govern the emergent self-similar dynamics of far-from-equilibrium quantum systems, from ultrarelativistic nuclear collisions to cold-atom experiments. Within…
Universal Equilibration Condition for Heavy Quarks
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Urs Achim Wiedemann
Kinetic equilibration at late times is physically required for heavy particles in a finite temperature medium. In Fokker-Planck dynamics, it is ensured by the Einstein relation bet…
A correspondence between the Rabi model and an Ising model with long-range interactions
Bruno Scheihing-Hitschfeld, Néstor Sepúlveda
By means of Trotter's formula, we show that transition amplitudes between a class of generalized coherent states in the Rabi model can be understood in terms of a certain Ising mod…
Heavy flavor transport in the QGP medium
Bruno Scheihing-Hitschfeld
I review recent developments on heavy flavor transport in the QGP medium, along two directions. The first is the transport of individual open heavy quarks. Leveraging the tools of…
