We study the phase diagram and transport properties of arbitrarily doped quantum wires functionalized by magnetic adatoms. The appropriate theoretical model for these systems is a dense one-dimensional Kondo lattice (KL) which consists of itinerant e

We study the Kondo chain in the regime of high spin concentration where the low energy physics is dominated by the Ruderman–Kittel–Kasuya–Yosida interaction. As has been recently shown (Tsvelik and Yevtushenko 2015 Phys. Rev. Lett. http://dx.do

In this paper, I present a conjecture for the Bethe ansatz equations for the model describing a star junction of M quantum critical Ising chains. For $M>3$ such a model exhibits the so-called topological Kondo effect (Beri and Cooper 2012 Phys. Rev.

We study a quantum phase transition in a system of dipoles confined in a stack of N identical one-dimensional lattices (tubes) polarized perpendicularly to the lattices. In this arrangement, the intra-lattice interaction is purely repulsive, preventi

Abstract Ultrafast control of structural and electronic properties of various quantum materials has recently sparked great interest. In particular, photoinduced switching between distinct topological phases has been considered a promising route to re

The behavior of quantum magnets depends strongly on the effective dimensionality of the inter-spin interactions. Here the authors tune the influence of two- and three-dimensional couplings in Yb2Pt2Pb with a magnetic field and hence control the behav

Low dimensional quantum magnetic excitations are intriguing but the experimental realizations are challenging. Here, the authors demonstrate Tomonaga–Luttinger behavior and spinon confinement in rare-earth perovskite YbAlO3 by inelastic neutron sca

We review the solution of QCD in two spacetime dimensions. Following the analysis of Baluni, for a single flavor, the model can be analyzed using Abelian bosonization. The theory can be analyzed in strong coupling, when the quarks are much lighter th
