Flavour current correlators and the non-Abelian hydrodynamic approximation: the charged sector
Thomas Apostolidis, Matti Järvinen, Elias Kiritsis +3
Flavor-current correlators are studied in strongly-coupled dense (holographic) matter, at finite quark chemical potential and finite isospin asymmetry. The non-Abelian hydro…

Dynamical Tidal Response of Neutron Stars: from Effective Field Theory to Gravitational Waveforms
Thomas Apostolidis, Valerio De Luca, Leonardo Gualtieri +3
We investigate the fully relativistic dynamical tidal response of neutron stars up to second order in the frequency. Combining the worldline effective field theory for extended gra…

Higher derivative holography and temperature dependence of QGP viscosities
Thomas Apostolidis, Umut Gürsoy, Edwan Préau
Recent Bayesian analyses of heavy ion collision data have established a non-trivial temperature dependence of the shear and bulk viscosity per entropy. Motivated by this, we consid…
