Holographic Spread Complexity at Fixed Charge: Routhians, Branes and Strings
Dimitrios Chatzis, Madison Hammond, Carlos Nunez +2
Holographic spread (Krylov) complexity relates the growth of a boundary state's complexity to the proper radial momentum of a probe falling into the bulk. Unitary evolution makes s…
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…
Holographic Spread Complexity from Branes and Strings
Dimitrios Chatzis, Madison Hammond, Carlos Nunez +2
We study Krylov spread complexity in holographic theories using genuine string-theory probes. Building on the proposal that the growth rate of spread complexity is measured by a pr…
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…
