A condensed matter realization of the axial magnetic effect

Maxim N. Chernodub, Alberto Cortijo, Adolfo G. Grushin +2

The axial magnetic effect, i.e., the generation of an energy current parallel to an axial magnetic field coupling with opposite signs to left- and right-handed fermions is a non-di…

A magnetic instability of the non-Abelian Sakai-Sugimoto model

Nele Callebaut, David Dudal

In this follow-up paper of 1105.2217 we further discuss the occurrence of a magnetically induced tachyonic instability of the rho meson in the two-flavour Sakai-Sugimoto model, upl…

The (IR-)relevance of the Gribov ambiguity in SU(2) x U(1) gauge theories with fundamental Higgs matter

M. A. L. Capri, D. Dudal, M. S. Guimaraes +3

It is well accepted that dealing with the Gribov ambiguity has a major impact on correlation functions in gauge-fixed Yang-Mills theories, in particular in the low momentum regime…

Random Walks in Rindler Spacetime and String Theory at the Tip of the Cigar

T. G. Mertens, H. Verschelde, V. I. Zakharov

In this paper, we discuss Rindler space string thermodynamics from a thermal scalar point of view as an explicit example of the results obtained in JHEP 1402 (2014) 127. We discuss…

Spontaneous breaking of the BRST symmetry in presence of the Gribov horizon: renormalizability

M. A. L. Capri, D. Dudal, M. S. Guimaraes +3

An all orders algebraic proof of the multiplicative renormalizability of the novel formulation of the Gribov-Zwanziger action proposed in Phys. Rev. D 86, 045005 (2012) [arXiv:1205…

SU(2) x U(1) Yang-Mills theories in 3d with Higgs field and Gribov ambiguity

M. A. L. Capri, D. Dudal, M. S. Guimaraes +3

We study the structure of the gauge propagators of a 3d version of the electroweak interaction in terms of the Higgs vacuum expectation value nu, of the non-Abelian gauge coupling…

Near-Hagedorn Thermodynamics and Random Walks: a General Formalism in Curved Backgrounds

T. G. Mertens, H. Verschelde, V. I. Zakharov

In this paper we discuss near-Hagedorn string thermodynamics starting from the explicit path integral derivation recently found by JHEP 0607 (2006) 031. Their result is extended an…

On the transition temperature(s) of magnetized two-flavour holographic QCD

N. Callebaut, D. Dudal

During heavy ion collisions, high temperatures and strong magnetic fields are generated. We employ the gauge-gravity duality to study the N_f=2 QCD phase diagram under these extrem…

An all-order proof of the equivalence between Gribov's no-pole and Zwanziger's horizon conditions

M. A. L. Capri, D. Dudal, M. S. Guimaraes +2

The quantization of non-Abelian gauge theories is known to be plagued by Gribov copies. Typical examples are the copies related to zero modes of the Faddeev-Popov operator, which g…
