Quantum critical properties of non-Hermitian XY models with magnetic field
Jia-Jia Luo, Volker Meden
The characterization of the quantum critical properties of genuine non-Hermitian many-body systems remains ambiguous as neither the state considered nor the definition of expectati…
Investigating the roots of the nonlinear Luttinger liquid phenomenology
L. Markhof, M. Pletyukhov, V. Meden
The nonlinear Luttinger liquid phenomenology of one-dimensional correlated Fermi systems is an attempt to describe the effect of the band curvature beyond the Tomonaga-Luttinger li…
Phase lapses in transmission through interacting two-level quantum dots
C. Karrasch, T. Hecht, A. Weichselbaum +3
We investigate the appearance of pi lapses in the transmission phase theta of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization…
Correlation induced resonances in transport through coupled quantum dots
V. Meden, F. Marquardt
We investigate the effect of local electron correlations on transport through parallel quantum dots. The linear conductance as a function of gate voltage is strongly affected by th…
Junctions of one-dimensional quantum wires - correlation effects in transport
X. Barnabe-Theriault, A. Sedeki, V. Meden +1
We investigate transport of spinless fermions through a single site dot junction of M one-dimensional quantum wires. The semi-infinite wires are described by a tight-binding model.…
Functional renormalization group approach to zero-dimensional interacting systems
R. Hedden, V. Meden, Th. Pruschke +1
We apply the functional renormalization group method to the calculation of dynamical properties of zero-dimensional interacting quantum systems. As case studies we discuss the anha…
