Ultrafast coupled charge and spin dynamics in strongly correlated NiO
Konrad Gillmeister, Denis Golež, Cheng-Tien Chiang +5
Charge excitations across an electronic band gap play an important role in opto-electronics and light harvesting. In contrast to conventional semiconductors, studies of above-band-…
Finite-temperature topological invariant for interacting systems
Razmik Unanyan, Maximilian Kiefer-Emmanouilidis, Michael Fleischhauer
We generalize the Ensemble Geometric Phase (EGP), recently introduced to classify the topology of density matrices, to finite-temperature states of interacting systems in one spati…
Dirac Spin Liquid on the Spin-1/2 Triangular Heisenberg Antiferromagnet
Shijie Hu, W. Zhu, Sebastian Eggert +1
We study the spin liquid candidate of the spin- - Heisenberg antiferromagnet on the triangular lattice by means of density matrix renormalization group (DMRG) simula…
Decoherence of charge density waves in beam splitters for interacting quantum wires
Andreas Schulz, Imke Schneider, James Anglin
Simple intersections between one-dimensional channels can act as coherent beam splitters for non-interacting electrons. Here we examine how coherent splitting at such intersections…
