Critical scaling of the AC conductivity and momentum dissipation
N. Angelinos, E. Kiritsis, F. Peña-Benitez
The scaling of the AC conductivity in quantum critical holographic theories at finite density, finite temperature and in the presence of momentum dissipation is considered. It is s…
Global symmetries, hidden sectors and emergent (dark) vector interactions
Panagiotis Betzios, Elias Kiritsis, Vasilis Niarchos +1
Hidden theories coupled to the SM may provide emergent (dark) vectors, that are composites/bound-states of the hidden fields. This is motivated by paradigms emerging from the AdS/C…
Holographic QFTs on SS, spontaneous symmetry breaking and Efimov saddle points
Elias Kiritsis, Francesco Nitti, Edwan Préau
Holographic CFTs and holographic RG flows on space-time manifolds which are -dimensional products of spheres are investigated. On the gravity side, this corresponds to Einstein-…
Back-reaction in massless de Sitter QFTs: holography, gravitational DBI action and f(R) gravity
Jewel Kumar Ghosh, Elias Kiritsis, Francesco Nitti +1
We employ gauge-gravity duality to study the backreaction effect of 4-dimensional large- quantum field theories on constant-curvature backgrounds, and in particular de Sitter sp…
The self-tuning of the cosmological constant and the holographic relaxion
Yuta Hamada, Elias Kiritsis, Francesco Nitti +1
We propose a brane-world setup based on gauge/gravity duality that permits the simultaneous realisation of self-tuning of the cosmological constant and a stabilisation of the elect…
