This paper introduces a minimal generalization of the SYK model, which exhibits a superconducting dome. A pseudogap phase, which appears next to the dome, is dominated by the strong quantum fluctuations. The pseudogap-superconductivity transition can

We investigate existence of replica off-diagonal solutions in the field-theoretical description of Sachdev-Ye-Kitaev model. To this end we evaluate a set of local and non-local dynamic correlation functions in the long time limit. We argue that the s

We study stability of multiple conducting edge states in a topological insulator against all multi-particle perturbations allowed by the time-reversal symmetry. We model a system as a multi-channel Luttinger liquid, where the number of channels equal
We investigate the effect of both strong and weak potential scattering caused by local impurities and extended (line) defects in the array of Luttinger liquid wires. We find that in both cases a finite range inter-wire interaction stabilises metallic

In this paper, we review the theory of spin switching for systems of different sizes, from a quantum mechanical master equation approach for small atomic clusters to the quasiclassical description of spin dynamics by a stochastic Landau–Lifshits–

We formulate a generalized Chalker-Coddington network model that describes the effect of nuclear spins on the two-dimensional electron gas in the quantum Hall regime. We find exact analytical expression for spin-dependent transmission coefficients of

We consider the spin and orbital Kondo effect in a parallel arrangement of two strongly electrostatically coupled quantum dots. Increasing the exchange of electrons between the dots through the attached leads induces a transition between the SU(4) sp

We have found a manifestation of spin–orbit Berry phase in the conductance of a mesoscopic loop with Rashba spin–orbit coupling placed in the external magnetic field which is perpendicular to the loop plain. The transmission probabilities at diff

Phononless plasmon-assisted transport through a long disordered array of finite length quantum wires is investigated analytically. Two temperature regimes, the low- and the high-temperature ones with qualitatively different temperature dependencies o

The current–voltage ( I – V ) characteristics for perpendicular transport through two sequentially coupled wires of finite length is calculated analytically. Due to interwire interactions, the positions of steps in the I – V characteristics shi
