This is a review of the Sachdev-Ye-Kitaev (SYK) model of compressible quantum many-
body systems without quasiparticle excitations, and its connections to various theoretical …

Spectral correlations are a powerful tool to study the dynamics of quantum many-body
systems. For Hermitian Hamiltonians, quantum chaotic motion is related to random matrix …

We propose the Sachdev-Ye-Kitaev Lindbladian as a paradigmatic solvable model of
dissipative many-body quantum chaos. It describes N strongly coupled Majorana fermions …

We study the out-of-equilibrium dynamics of a Sachdev-Ye-Kitaev (SYK) model, N fermions
with aq-body interaction of infinite range, coupled to a Markovian environment. Close to the …

Wormholes are intriguing classical solutions in General Relativity, that have fascinated
theoretical physicists for decades. In recent years, especially in Holography, gravitational …

We study a large-N tensor model with O (N) 3 symmetry containing two flavors of Majorana
fermions, ψ 1 abc and ψ 2 abc. We also study its random counterpart consisting of two …

A possible solution of the information paradox can be sought in quantum information
scrambling. In this paradigm, it is postulated that all information entering a black hole is …

A bstract We study the real time formation of the ground state of two coupled SYK models.
This is a highly entangled state which is close to the thermofield double state and can be …

We study a sparse Sachdev-Ye-Kitaev (SYK) model with N Majoranas where only∼ k N
independent matrix elements are nonzero. We identify a minimum k≳ 1 for quantum chaos …

We study a two-site Sachdev-Ye-Kitaev (SYK) model with complex couplings, and identify a
low temperature transition to a gapped phase characterized by a constant in temperature …
