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…
Holographic Black Hole Formation and Scrambling in Time-Ordered Correlators
Pratyusha Chowdhury, Felix M. Haehl, Adrián Sánchez-Garrido +1
We describe a holographic mechanism for black hole formation via the collision of two shock waves in three-dimensional anti-de Sitter spacetime. In the dual conformal field theory…
Mind the crosscap: -scaling in non-orientable gravity and time-reversal-invariant systems
Gabriele Di Ubaldo, Altay Etkin, Felix M. Haehl +1
Spectral statistics of quantum chaotic systems are governed by random matrix universality. In many cases of interest, time-reversal symmetry selects the Gaussian Orthogonal Ensembl…
Virasoro OPE Blocks, Causal Diamonds, and Higher-Dimensional CFT
Felix M. Haehl, Kuo-Wei Huang
In two-dimensional Conformal Field Theory (CFT), multi-stress tensor exchanges between probe operators give rise to the Virasoro identity conformal block, which is fixed by symmetr…
Modular-invariant random matrix theory and AdS wormholes
Jan Boruch, Gabriele Di Ubaldo, Felix M. Haehl +2
We develop a non-perturbative definition of RMT: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Gi…
Records from the S-Matrix Marathon: Schwinger-Keldysh Formalism
Felix M. Haehl, Mukund Rangamani
These notes provide an overview of real-time techniques in quantum field theories and holography. We outline the general rationale and principles underlying the Schwinger-Keldysh f…
