Conducting fixed points for inhomogeneous quantum wires: a conformally invariant boundary theory
N. Sedlmayr, D. Morath, J. Sirker +2
Inhomogeneities and junctions in wires are natural sources of scattering, and hence resistance. A conducting fixed point usually requires an adiabatically smooth system. One notabl…
Transport and scattering in inhomogeneous quantum wires
N. Sedlmayr, J. Ohst, I. Affleck +2
We consider scattering and transport in interacting quantum wires that are connected to leads. Such a setup can be represented by a minimal model of interacting fermions with inhom…
Chain breaks and the susceptibility of Sr_2Cu_{1-x}Pd_xO_{3+δ} and other doped quasi one-dimensional antiferromagnets
J. Sirker, N. Laflorencie, S. Fujimoto +2
We study the magnetic susceptibility of one-dimensional S=1/2 antiferromagnets containing non-magnetic impurities which cut the chain into finite segments. For the susceptibility o…
Reply to the "Comment on 'Phase diagram of an impurity in the spin-1/2 chain: two channel Kondo effect versus Curie law'"
Sebastian Eggert, David P. Gustafsson, Stefan Rommer
In a comment by A.A. Zvyagin the phase diagram in our Letter [Phys. Rev. Lett. 86, 516 (2001)] was critisized of being incomplete and a new fixed point was suggested. We show that…
Phase diagram of an impurity in the spin-1/2 chain: two channel Kondo effect versus Curie law
Sebastian Eggert, David P. Gustafsson, Stefan Rommer
We consider a magnetic s=1/2 impurity in the antiferromagnetic spin chain as a function of two coupling parameters: the symmetric coupling of the impurity to two sites in the chain…
Scanning Tunneling Microscopy of a Luttinger Liquid
Sebastian Eggert
Explicit predictions for Scanning Tunneling Microscopy (STM) on interacting one-dimensional electron systems are made using the Luttinger liquid formalism. The STM current changes…
