Solvable models of quantum black holes: a review on Jackiw–Teitelboim gravity [PDF]

open access: yesLiving Reviews in Relativity, 2022
We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable model of quantum gravity in two dimensions (that arises e.g. from the s-wave sector of higher dimensional gravity systems with spherical symmetry).

Translationally Invariant Non-Fermi-Liquid Metals with Critical Fermi Surfaces: Solvable Models [PDF]

open access: yesPhysical Review X, 2018
Understanding the properties of metals beyond the Fermi liquid paradigm is one of the central challenges of condensed matter physics. New exactly solvable microscopic models of non-Fermi liquid metals offer new insights into many properties of these ...

Analytically Solvable Renormalization Group for the Many-Body Localization Transition. [PDF]

open access: yesPhysical Review Letters, 2018
We introduce a simple, exactly solvable strong-randomness renormalization group (RG) model for the many-body localization (MBL) transition in one dimension.

A solvable irrelevant deformation of AdS3/CFT2 [PDF]

open access: yes, 2017
A bstractRecently we proposed a universal solvable irrelevant deformation of AdS3/CFT2 duality, which leads in the ultraviolet to a theory with a Hagedorn entropy [1].

Residually finite rationally solvable groups and virtual fibring [PDF]

open access: yes, 2018
We show that a finitely generated residually finite rationally solvable (or RFRS) group $G$ is virtually fibred, in the sense that it admits a virtual surjection to $\mathbb{Z}$ with a finitely generated kernel, if and only if the first $L^2$-Betti ...

Lie Solvable Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1985
Let R be an associative ring with 1 and let \(L=L(R)\) be its associated Lie ring. Assume that L is solvable of length n. It is shown here that if 3 is invertible in R, then the ideal J of R generated by all elements of the form [[[a,b],[c,d]],e] is nilpotent of index bounded by \(10^{n-2}\) for \(n\geq 3\).

Characterizations of Fitting p-Groups whose Proper Subgroups are Solvable [PDF]

open access: yesAdvances in Group Theory and Applications, 2017
This work continues the study of infinitely generated groups whose proper subgroups are solvable and in whose homomorphic images normal closures of finitely generated subgroups are residually nilpotent. In [4], it has been shown that such a group, if not

One-Dimensional Quasi-Exactly Solvable Schr\"odinger Equations [PDF]

open access: yes, 2016
Quasi-Exactly Solvable Schrodinger Equations occupy an intermediate place between exactly-solvable (e.g. the harmonic oscillator and Coulomb problems etc) and non-solvable ones. Mainly, they were discovered in the 1980ies.

A second order in time, uniquely solvable, unconditionally stable numerical scheme for Cahn-Hilliard-Navier-Stokes equation [PDF]

open access: yesJournal of Computational Physics, 2014
We propose a novel second order in time numerical scheme for Cahn-Hilliard-Navier-Stokes phase field model with matched density. The scheme is based on second order convex-splitting for the Cahn-Hilliard equation and pressure-projection for the Navier ...

The quest for solvable multistate Landau-Zener models [PDF]

open access: yes, 2017
Recently, integrability conditions (ICs) in mutistate Landau-Zener (MLZ) theory were proposed []. They describe common properties of all known solved systems with linearly time-dependent Hamiltonians.
