Size Operator and Spectral Clustering in the Two Coupled SYK Model
Juan Santos-Suárez, Juan Santos-Suárez, Martà Berenguer +3
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…
Chiral symmetry breaking and restoration by helical magnetic fields in AdS/CFT
Martà 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
Martà 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…
Hamiltonian Forging of a Thermofield Double
Daniel FaÃlde, Juan Santos-Suárez, David A. Herrera-Martà +1
We address the variational preparation of the Thermofield Double as the ground state of a suitably engineered Hamiltonian acting on the doubled Hilbert space. Through the use of th…
Floquet SYK wormholes
Martà 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…
Multitrace deformations and the nonlinear stability of Anti-de Sitter space
Alexandre Serantes, David Travieso Mayo, Javier Mas
We investigate the nonlinear stability of global Anti-de Sitter space in the presence of multitrace deformations utilizing an Einstein-Klein-Gordon system with a top-down scalar po…
