Lindblad-driven recombination of the X(3872) tetraquark
Néstor Armesto, Miguel Ángel Escobedo, Elena G. Ferreiro +1
The internal structure of the exotic meson X(3872) remains an open question. We investigate its production in heavy-ion collisions under the hypothesis that it is a compact tetraqu…

Optimal observables for (non-)equilibrium quantum metrology from the master equation
Víctor López-Pardo, Alexander Rothkopf
We demonstrate how observables with optimal sensitivity to environmental properties can be constructed explicitly from the master equation of an open-quantum system. Our approach d…

Exploring the DGLAP resummation in the JIMWLK Hamiltonian
Néstor Armesto, Alex Kovner, Víctor López-Pardo
We explore the recently derived equation that resums DGLAP corrections to the JIMWLK Hamiltonian in the simplified setting of the SU(2) gauge theory. We solve the equation numerica…
