Time-dependent quantum transport: causal superfermions, exact fermion-parity protected decay mode, and Pauli exclusion principle for mixed quantum states

R. B. Saptsov, M. R. Wegewijs

We extend the recently developed causal superfermion approach to the real-time transport theory to time-dependent decay problems.Its usefulness is illustrated for the Anderson mode…

Interplay between Point-Group Symmetries and the Choice of the Bloch Basis in Multiband Models

Stefan A. Maier, Carsten Honerkamp, Qiang-Hua Wang

We analyze the point-group symmetries of generic multiband tight-binding models with respect to the transformation properties of the effective interactions. While the vertex functi…

Multiorbital effects in the functional renormalization group: A weak-coupling study of the Emery model

Stefan A. Maier, Jutta Ortloff, Carsten Honerkamp

We perform an instability analysis of the Emery three-band model at hole doping and weak coupling within a channel-decomposed functional renormalization group flow proposed in Phys…

Functional renormalization group study of the Anderson--Holstein model

M. A. Laakso, D. M. Kennes, S. G. Jakobs +1

We present a comprehensive study of the spectral and transport properties in the Anderson--Holstein model both in and out of equilibrium using the functional renormalization group…

Edge theories in Projected Entangled Pair State models

S. Yang, L. Lehman, D. Poilblanc +4

We study the edge physics of gapped quantum systems in the framework of Projected Entangled Pair State (PEPS) models. We show that the effective low-energy model for any region act…

Field-induced superfluids and Bose liquids in Projected Entangled Pair States

Didier Poilblanc, Norbert Schuch, J. Ignacio Cirac

In two-dimensional incompressible quantum spin liquids, a large enough magnetic field generically induces "doping" of polarized S=1 triplons or S=1/2 spinons. We review a number of…
