Spectral functions of strongly interacting isospin-1/2 bosons in one dimension
K. A. Matveev, A. Furusaki
We study a system of one-dimensional (iso)spin-1/2 bosons in the regime of strong repulsive interactions. We argue that the low-energy spectrum of the system consists of acoustic d…
Electronic transport in inhomogeneous quantum wires
J. Rech, K. A. Matveev
We study the transport properties of a long non-uniform quantum wire where the electron-electron interactions and the density vary smoothly at large length scales. We show that the…
Resistivity of inhomogeneous quantum wires
J. Rech, K. A. Matveev
We study the effect of electron-electron interactions on the transport in an inhomogeneous quantum wire. We show that contrary to the well-known Luttinger liquid result, non-unifor…
Bosonization of strongly interacting electrons
K. A. Matveev, A. Furusaki, L. I. Glazman
Strong repulsive interactions in a one-dimensional electron system suppress the exchange coupling J of electron spins to a value much smaller than the Fermi energy E_F. The convent…
Strong tunneling and charge quantization in S-I-N Coulomb blockade structures
K. A. Matveev, L. I. Glazman
We study the charge of a small normal island connected by a tunnel junction to a superconducting lead. Unlike the N-I-N case, the steps of the Coulomb staircase remain sharp even i…
