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

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…
Flavored anisotropic black holes
Ana Garbayo, Carlos Hoyos, Niko Jokela +2
We construct a black hole geometry dual to a (2+1)-dimensional defect in an ambient (3+1)-dimensional gauge theory at non-zero temperature and quark density. The geometry is a solu…
Risking your NEC
Carlos Hoyos, Niko Jokela, Jose Manuel Penín +2
Energy conditions, especially the null energy condition (NEC), are generically imposed on solutions to retain a physically sensible classical field theory and they also play an imp…
Holographic Floquet states in low dimensions (I)
Ana Garbayo, Javier Mas, Alfonso V. Ramallo
We study the response of a (2+1)-dimensional gauge theory to an external rotating electric field. In the strong coupling regime such system is formulated holographically in a top-d…
Holographic spontaneous anisotropy
Carlos Hoyos, Niko Jokela, José Manuel Penín +1
We construct a family of holographic duals to anisotropic states in a strongly coupled gauge theory. On the field theory side the anisotropy is generated by giving a vacuum expecta…

Ulf Gran, Niko Jokela, Daniele Musso +2
We describe a strongly coupled layered system in 3+1 dimensions by means of a top-down D-brane construction. Adjoint matter is encoded in a large- stack of D3-branes, while fu…
