Perturbative, Nonperturbative and Exact Aspects of Crystalline Phases in the Gross-Neveu Model
Francesco Benini, Ohad Mamroud, Tomas Reis +1
We study the crystalline phase of the Gross--Neveu model with a chemical potential for of the fermions. We analyze the problem in three independent ways: using…
Chaos of Berry curvature for BPS microstates
Yiming Chen, Sean Colin-Ellerin, Ohad Mamroud +1
We expect black hole microstates to differ in their chaotic properties from states associated with other geometries. For supersymmetric black holes, ordinary level statistics canno…
Condensates, crystals, and renormalons in the Gross-Neveu model at finite density
Francesco Benini, Ohad Mamroud, Tomas Reis +1
We study the symmetric Gross-Neveu model at finite density in the presence of a chemical potential for a generic number of fermion fields. By combin…
Twisted times, the Schwarzian and its deformations in DSSYK
Micha Berkooz, Ronny Frumkin, Ohad Mamroud +1
The IR dynamics of SYK is that of the Schwarzian theory, the effective theory of broken reparametrization invariance. In the double scaling limit, SYK is completely solvable by cho…
A Cordial Introduction to Double Scaled SYK
Micha Berkooz, Ohad Mamroud
We review recent progress regarding the double scaled Sachdev-Ye-Kitaev model and other -local quantum mechanical random Hamiltonians. These models exhibit an expansion using ch…
A Path Integral for Chord Diagrams and Chaotic-Integrable Transitions in Double Scaled SYK
Micha Berkooz, Nadav Brukner, Yiyang Jia +1
We study transitions from chaotic to integrable Hamiltonians in the double scaled SYK and -spin systems. The dynamics of our models is described by chord diagrams with two speci…
