Gravitational form factors of the proton in the improved holographic QCD model

Antti Hippeläinen, Niko Jokela, Matti Järvinen

We compute the gluonic contribution to the gravitational form factors of the proton using the improved holographic QCD model, in which the proton is described in terms of bulk Dira…

Locating the QCD critical point with neutron-star observations

Christian Ecker, Niko Jokela, Matti Järvinen

We present a probabilistic model for the QCD critical endpoint (CEP) and the equation of state (EOS) at -equilibrium, constrained by neutron-star observations. Using a hybrid f…

Predictions for neutron star mergers from the gauge/gravity duality

Matti Jarvinen

The gauge/gravity duality, combined with information from lattice QCD, nuclear theory, and perturbative QCD, can be used to constrain the equation of state of hot and dense QCD. I…

Phases and Phase transitions of U(1)SU(2) symmetric holographic matter

Matti Järvinen, Elias Kiritsis, Francesco Nitti +1

The phase diagram and symmetry breaking patterns of a holographic CFT with U(1)SU(2) symmetry are analyzed using the simplest holographic action, namely Einstein-Yang-Mills…

A black hole effective theory for strongly interacting matter

Matti Jarvinen, Dorin Weissman

We establish a new tool for studying strongly coupled matter: an effective theory of black holes in gravity, which maps to a hydrodynamic description of field theories via the gaug…

Modulated instabilities and the AdS point in dense holographic matter

Jesús Cruz Rojas, Tuna Demircik, Matti Järvinen

We investigate fluctuations of hot and dense QCD plasma by using the gauge/gravity duality. To this end, we carry out a comprehensive classification and analysis of quasinormal mod…
