A symmetry-based resolution of pseudo-gauge ambiguities in local equilibrium
Carlos Hoyos
The total angular momentum current can be decomposed into orbital and spin contributions in different ways, known as pseudo-gauges. This freedom leads to ambiguities in the definit…
Pseudo-gauge invariant non-equilibrium density operator
F. Becattini, C. Hoyos
We obtain a form of the local thermodynamic equilibrium density operator which is invariant under pseudo-gauge transformations of the stress-energy and the spin tensors. This opera…
Subtleties of non-Abelian D-brane actions and their effect on holographic heavy-light meson spectra
Carlos Hoyos, Niko Jokela, Andrea Olzi
We revisit the holographic description of heavy light mesons in the D3-D7 system at zero temperature, analyzing the dynamics of the coupled probe D7 branes through the non-Abelian…
Thermal response of the Nieh-Yan term
Carlos Hoyos, Niko Jokela, José Manuel Penin
We reinterpret the Nieh-Yan (NY) anomaly using holography, finding that the U(1) axial symmetry remains unbroken and the axial current coupling to an external gauge field is conser…
Weak rates in strongly coupled cold quark matter
Carlos Hoyos, Andrea Olzi, David Rodriguez-Fernandez
The rates of flavor-changing weak processes are crucial in determining the conditions of beta equilibrium in neutron stars and mergers, influencing the damping of oscillations, the…
Estimate for the bulk viscosity of strongly coupled quark matter using perturbative QCD and holography
Jesús Cruz Rojas, Tyler Gorda, Carlos Hoyos +6
Modern hydrodynamic simulations of core-collapse supernovae and neutron-star mergers require knowledge not only of the equilibrium properties of strongly interacting matter, but al…
