Anomalous Transport from Kubo Formulae

- K. Landsteiner, E. Megías, F. Peña-Benitez
- Physics
- 24 July 2012

Chiral anomalies have profound impact on the transport properties of relativistic fluids. In four dimensions there are different types of anomalies, pure gauge and mixed gauge-gravitational… Expand

Holographic gravitational anomaly and chiral vortical effect

- K. Landsteiner, E. Megías, L. Melgar, F. Peña-Benitez
- Physics
- 2 July 2011

We analyze a holographic model with a pure gauge and a mixed gauge-gravitational Chern-Simons term in the action. These are the holographic implementations of the usual chiral and the mixed… Expand

Naturally light dilatons from nearly marginal deformations

- E. Megías, O. Pujolàs
- Physics
- 20 January 2014

A bstractWe discuss the presence of a light dilaton in CFTs deformed by a nearlymarginal operator O$$ \mathcal{O} $$, in the holographic realizations consisting of confining RG flows that end on a… Expand

Frequency dependence of the Chiral Vortical Effect

- K. Landsteiner, E. Megías, Francisco Pena Ben'itez
- Physics
- 4 December 2013

We study the frequency dependence of all the chiral vortical and magnetic conductivities for a relativistic gas of free chiral fermions and for a strongly coupled conformal field theory with… Expand

Holographic gravitational anomaly in first and second order hydrodynamics

- E. Megías, F. Peña-Benitez
- Physics, Geology
- 19 April 2013

A bstractWe compute, in the framework of the fluid/gravity correspondence, the transport coefficients of a relativistic fluid affected by chiral and gauge-gravitational anomalies, including external… Expand

Thermal heat kernel expansion and the one-loop effective action of QCD at finite temperature

- E. Megías, E. Arriola, L. L. Salcedo
- Physics
- 10 December 2003

The heat kernel expansion for field theory at finite temperature is constructed. It is based on the imaginary time formalism and applies to generic Klein-Gordon operators in flat space-time. Full… Expand

Cosmological phase transitions in warped space: gravitational waves and collider signatures

- E. Megías, G. Nardini, M. Quirós
- PhysicsJournal of High Energy Physics
- 13 June 2018

A bstractWe study the electroweak phase transition within a 5D warped model including a scalar potential with an exponential behavior, and strong back-reaction over the metric, in the infrared. By… Expand

A natural origin for the LHCb anomalies

- E. Megías, G. Panico, O. Pujolàs, M. Quirós
- Physics
- 8 August 2016

A bstractThe anomalies recently found by the LHCb collaboration in B-meson decays seem to point towards the existence of new physics coupled non-universally to muons and electrons. We show that a… Expand
