4 p, 246.1 KB Trouble finding the optimal AdS/QCD / Veschgini, Kambis (Institut für Theoretische Physik der Universität Heidelberg) ; Megías Fernández, Eugenio (Institut für Theoretische Physik der Universität Heidelberg) ; Pirner, Hans Jürgen (Institut für Theoretische Physik der Universität Heidelberg)
In the bottom-up approach to AdS/QCD based on a five-dimensional gravity dilaton action the exponential of the dilaton field is usually identified as the strong or 't Hooft coupling. There is currently no model known which fits the measurements of the running coupling and lattice results for pressure at the same time. [...]

4 p, 111.8 KB Gravitational anomaly and transport phenomena / Landsteiner, Karl (Universidad Autónoma de Madrid. Instituto de Física Teórica) ; Megías Fernández, Eugenio (Universitat Autònoma de Barcelona. Departament de Física) ; Pena-Benítez, Francisco (Universidad Autónoma de Madrid. Instituto de Física Teórica) ; American Physical Society
Quantum anomalies give rise to new transport phenomena. In particular, a magnetic field can induce an anomalous current via the chiral magnetic effect and a vortex in the relativistic fluid can also induce a current via the chiral vortical effect. [...]

7 p, 117.5 KB Polyakov loop and the Hadron resonance gas model / Megías Fernández, Eugenio (Universitat Autònoma de Barcelona. Departament de Física) ; Ruiz Arriola, E. (Universidad de Granada. Departamento de Física Atómica, Molecular y Nuclear) ; Salcedo, L. L. (Universidad de Granada. Departamento de Física Atómica, Molecular y Nuclear) ; American Physical Society
The Polyakov loop has been used repeatedly as an order parameter in the deconfinement phase transition in QCD. We argue that, in the confined phase, its expectation value can be represented in terms of hadronic states, similarly to the hadron resonance gas model for the pressure. [...]
