The cosmological necklace problem
Andreas Blommaert, Jonah Kudler-Flam, Vladimir Narovlansky +1
We investigate 3d de Sitter axion wormhole which contribute to the no-boundary density matrix. We identify "cosmological necklace" solutions: an infinite series of Euclidean saddle…
Out-of-time-ordered Correlators in de Sitter Revisited
Alexey Milekhin, Vladimir Narovlansky, Jiuci Xu
We study the 4-point out-of-time-ordered correlator (OTOC) of scalar fields using the eikonal approximation to gravity around a de Sitter background. It can be defined in a gauge-i…
Towards a microscopic description of de Sitter dynamics
Vladimir Narovlansky
Describing dynamics in a gravitational universe with positive cosmological constant, such as de Sitter space, is a conceptually challenging problem. We propose a principle for cons…
On the three-point functions in timelike N=1 Liouville CFT
Beatrix Mühlmann, Vladimir Narovlansky, Ioannis Tsiares
We use analytic (super-)conformal bootstrap methods to derive explicit expressions for the structure constants of N=1 Liouville CFT in the `timelike' regime of the superconformal c…
Optimal bound on long-range distillable entanglement
Jonah Kudler-Flam, Vladimir Narovlansky, Nikita Sopenko
We prove an upper bound on long-range distillable entanglement in spatial dimensions. Namely, it must decay faster than , where is the distance between entangled regio…
Double-scaled SYK and de Sitter Holography
Vladimir Narovlansky, Herman Verlinde
We propose a new model of low dimensional de Sitter holography in the form of a pair of double-scaled SYK models at infinite temperature coupled via an equal energy constraint $H_L…
A supersymmetric SYK model with a curious low energy behavior
Anna Biggs, Juan Maldacena, Vladimir Narovlansky
We consider = 2, 4 supersymmetric SYK models that have a peculiar low energy behavior, with the entropy going like , where $a \neq…
Semiclassical geometry in double-scaled SYK
Akash Goel, Vladimir Narovlansky, Herman Verlinde
We argue that at finite energies, double-scaled SYK has a semiclassical approximation controlled by a coupling in which all observables are governed by a non-trivial saddle poi…
Ginzburg-Landau Description and Emergent Supersymmetry of the Minimal Model
Igor R. Klebanov, Vladimir Narovlansky, Zimo Sun +1
A pair of the 2D non-unitary minimal models is known to be equivalent to a variant of the minimal model. We discuss the RG flow from this model to another non-un…
Quantum groups, non-commutative , and chords in the double-scaled SYK model
Micha Berkooz, Mikhail Isachenkov, Prithvi Narayan +1
We study the double-scaling limit of SYK (DS-SYK) model and elucidate the underlying quantum group symmetry. The DS-SYK model is characterized by a parameter , and in the $q\rig…
Dualities between fermionic theories and the Potts model
Vladimir Narovlansky
We show that a large class of fermionic theories are dual to a limit of the Potts model in the presence of a magnetic field. These can be described using a statistical mo…
Negativity Spectra in Random Tensor Networks and Holography
Jonah Kudler-Flam, Vladimir Narovlansky, Shinsei Ryu
Negativity is a measure of entanglement that can be used both in pure and mixed states. The negativity spectrum is the spectrum of eigenvalues of the partially transposed density m…
Distinguishing Random and Black Hole Microstates
Jonah Kudler-Flam, Vladimir Narovlansky, Shinsei Ryu
This is an expanded version of the short report [Phys. Rev. Lett. 126, 171603 (2021)], where the relative entropy was used to distinguish random states drawn from the Wishart ensem…
Multi-trace Correlators in the SYK Model and Non-geometric Wormholes
Micha Berkooz, Nadav Brukner, Vladimir Narovlansky +1
We consider multi-energy level distributions in the SYK model, and in particular, the role of global fluctuations in the density of states of the SYK model. The connected contribut…
Complex Sachdev-Ye-Kitaev model in the double scaling limit
Micha Berkooz, Vladimir Narovlansky, Himanshu Raj
We solve for the exact energy spectrum, 2-point and 4-point functions of the complex SYK model, in the double scaling limit at all energy scales. This model has a global sym…
The double scaled limit of Super--Symmetric SYK models
Micha Berkooz, Nadav Brukner, Vladimir Narovlansky +1
We compute the exact density of states and 2-point function of the super-symmetric SYK model in the large double-scaled limit, by using combinatorial tools tha…
Towards a full solution of the large N double-scaled SYK model
Micha Berkooz, Mikhail Isachenkov, Vladimir Narovlansky +1
We compute the exact, all energy scale, 4-point function of the large double-scaled SYK model, by using only combinatorial tools and relating the correlation functions to sums…
Weak Coupling Limits and Colliding Punctures in Class-S Theories
Arel Genish, Vladimir Narovlansky
Class-S theories are four-dimensional N=2 supersymmetric field theories constructed by the reduction of a (2,0) six-dimensional theory on a punctured Riemann surface C (called the…
