Emergent gravity from hidden sectors and TT deformations
Panos Betzios, Elias Kiritsis, Vasilis Niarchos
We investigate emergent gravity extending the paradigm of the AdS/CFT correspondence. The emergent graviton is associated to the (dynamical) expectation value of the energy-momentu…
Holographic theories at finite -angle, CP-violation, glueball spectra and strong-coupling instabilities
Yuta Hamada, Elias Kiritsis, Francesco Nitti
A general class of holographic theories with a nontrivial -angle are analyzed. The instanton density operator is dual to a bulk axion field. We calculate the ground-state soluti…
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…
