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…

From Chaos to Integrability in Double Scaled SYK via a Chord Path Integral
Micha Berkooz, Nadav Brukner, Yiyang Jia +1
We study thermodynamic phase transitions between integrable and chaotic dynamics. We do so by analyzing models that interpolate between the chaotic double scaled Sachdev-Ye-Kitaev…

Bosonic near-CFT models from Fock-space fluxes
Yiyang Jia
We construct a family of near-CFT models with a conserved U(1) charge, whose basic degrees of freedom are canonical bosons. The Sachdev-Ye-Kitaev (SYK) model -- the first micro…
