Interaction induced dimerization in zigzag single wall carbon nanotubes
Sam T. Carr, Alexander O. Gogolin, Alexander A. Nersesyan
We derive a low-energy effective model of metallic zigzag carbon nanotubes at half filling. We show that there are three important features characterizing the low-energy properties…
Rashba coupling in quantum dots: exact solution
E. Tsitsishvili, G. S. Lozano, A. O. Gogolin
We present an analytic solution to the problem of the Rashba spin-orbit coupling in semiconductor quantum dots. We calculate the exact energy spectrum, wave-functions, and spin--fl…
Mechanically induced current and quantum evaporation from Luttinger liquids
Andrei Komnik, Alexander O. Gogolin
We investigate transport through a tunnelling junction between an uncorrelated metallic lead and a Luttinger liquid when the latter is subjected to a time dependent perturbation. T…
Multi-particle effects in non-equilibrium electron tunnelling and field emission
Andrei Komnik, Alexander O. Gogolin
We investigate energy resolved electric current from various correlated host materials under out-of-equilibrium conditions. We find that, due to a combined effect of electron-elect…
Intrinsic Coulomb blockade in multi-wall carbon nanotubes
R. Egger, A. O. Gogolin
Carbon nanotubes provide a new class of molecular wires that display new and exciting mesoscopic transport properties. We provide a detailed theoretical description for transport i…
Field emission from Luttinger liquids and single-wall carbon nanotubes
Alexander O. Gogolin, Andrei Komnik
We develop a theory for the field emission effect in Luttinger liquids and single-wall carbon nanotubes at the level of the energy resolved current distribution. We generalise Fowl…
Finite-temperature dynamical magnetic susceptibility of quasi-one-dimensional frustrated spin-1/2 Heisenberg antiferromagnets
Marc Bocquet, Fabian H. L. Essler, Alexei M. Tsvelik +1
We study the dynamical response of frustrated, quasi-one-dimensional spin-1/2 Heisenberg antiferromagnets at finite temperatures. We allow for the presence of a Dzyaloshinskii-Mori…
Critical properties of the double-frequency sine-Gordon model with applications
M. Fabrizio, A. O. Gogolin, A. A. Nersesyan
We study the properties of the double-frequency sine--Gordon model in the vicinity of the Ising quantum phase transition displayed by this model. Using a mapping onto a generalised…
Bosonization and Strongly Correlated Systems
A. O. Gogolin, A. A. Nersesyan, A. M. Tsvelik
This volume provides a detailed account of bosonization. The first part of the book examines the technical aspects of bosonization including one-dimensional fermions, the Gaussian…
From band insulator to Mott insulator in one dimension
Michele Fabrizio, Alexander O. Gogolin, Alexander A. Nersesyan
We derive the phase diagram for the one-dimensional model of a ferroelectric perovskite recently introduced by Egami, Ishihara and Tachiki [Science, {\bf 261}, 1307 (1993)]. We sho…
Theory Of The One Dimensional SU(4) Spin-Orbital Model
P. Azaria, A. O. Gogolin, P. Lecheminant +1
The one-dimensional spin-orbital model is studied by means of Abelian bosonization. We derive the low-energy effective theory which enables us to study small deviations from the SU…
Comment on "Electronic Properties of Armchair Carbon Nanotubes: Bosonization Approach"
R. Egger, A. O. Gogolin
We comment on the paper by H. Yoshioka and A. Odintsov, to appear in PRL, see cond-mat/9805106.
Crystal Distortion and the Two-Channel Kondo Effect
C. N. Hind, A. O. Gogolin
We study a simple model of the two-channel Kondo effect in a distorted crystal. This model is then used to investigate the interplay of the Kondo and Jahn-Teller effects, and also…
Incommensurate spin correlations in Heisenberg spin-1/2 zig-zag ladders
Alexander A. Nersesyan, Alexander O. Gogolin, Fabian H. L. Essler
We develop a low-energy effective theory for spin-1/2 frustrated two-leg Heisenberg spin ladders. We obtain a new type of interchain coupling that breaks parity symmetry. In the pr…
Correlated transport and non-Fermi liquid behavior in single-wall carbon nanotubes
Reinhold Egger, Alexander O. Gogolin
We derive the effective low-energy theory for single-wall carbon nanotubes including the Coulomb interactions among electrons. The generic model found here consists of two spin-1/2…
Exact Fermi-edge singularity exponent in a Luttinger liquid
Andrei Komnik, Reinhold Egger, Alexander O. Gogolin
We report the exact calculation of the Fermi-edge singularity exponent for correlated electrons in one dimension (Luttinger liquid). Focusing on the special interaction parameter g…
Comment on ``Enhancement of the Tunneling Density of States in Tomonaga-Luttinger Liquids''
Michele Fabrizio, Alexander O. Gogolin
In a recent Physical Review Letter, Oreg and Finkel'stein (OF) have calculated the electron density of states (DOS) for tunneling into a repulsive Luttinger liquid close to the loc…
