Tunneling resonances through periodically driven quantum dots
Jan Mathis Giesen, Daniel Weber, Sebastian Eggert
Periodic driving of quantum dots is analyzed as a basis for developing dynamic switching devices. We study transport through periodically modulated energy levels which are coupled…
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…
Numerical Evidence for Multiplicative Logarithmic Corrections from Marginal Operators
Sebastian Eggert
Field theory calculations predict multiplicative logarithmic corrections to correlation functions from marginally irrelevant operators. However, for the numerically most suitable m…
Impurities in S=1/2 Heisenberg Antiferromagnetic Chains: Consequences for Neutron Scattering and Knight Shift
Sebastian Eggert, Ian Affleck
Non-magnetic impurities in an S=1/2 Heisenberg antiferromagnetic chain are studied using boundary conformal field theory techniques and finite-temperature quantum Monte Carlo simul…
