Size Operator and Spectral Clustering in the Two Coupled SYK Model
Juan Santos-Suárez, Martí Berenguer, Javier Mas +1
At large , two coupled Sachdev-Ye-Kitaev models realize an eternal traversable wormhole with a discrete spectrum. We show that at finite the spectrum organizes into clusters…
The two-dimensional disordered sigma model
Martí Berenguer, Felix M. Haehl, Elisa Tabor
We introduce a two-dimensional nonlinear sigma model with random Gaussian -body interactions. The model combines the structure of a two-dimensional bosonic SYK-type quant…
Confinement and chiral symmetry breaking in holography: a smooth switch-off
Martí Berenguer, Johanna Erdmenger, Nick Evans +2
We revisit the holographic description of the thermal first order phase transition of N=4 SYM compactified on a spatial circle. At the transition, the dominant bulk saddle exchange…
Chiral symmetry breaking and restoration by helical magnetic fields in AdS/CFT
Martí Berenguer, Javier Mas, Masataka Matsumoto +2
We study the effects of helical magnetic fields on chiral symmetry breaking within the AdS/QCD framework using the D3/D7-brane model. By analyzing the brane embeddings, we obtain t…
Hot wormholes and chaos dynamics in a two-coupled SYK model
Martí Berenguer, Javier Mas, Juan Santos-Suárez +1
We study the dynamics of chaos across the phase transition in a 2-coupled Sachdev-Ye-Kitaev (SYK) model, with a focus on the unstable "hot wormhole" phase. Using the Schwinger-Keld…
Floquet SYK wormholes
Martí Berenguer, Anshuman Dey, Javier Mas +2
We study the non-equilibrium dynamics of two coupled SYK models, conjectured to be holographically dual to an eternal traversable wormhole in AdS. We consider different periodi…
Holographic Floquet states in low dimensions (II)
Martí Berenguer, Ana Garbayo, Javier Mas +1
We continue the study in [1] of a strongly coupled (2+1)-dimensional gauge theory subject to an external rotating electric field. The system is modelled holographically as a D3/D5…
