Quantitative functional renormalization for three-dimensional quantum Heisenberg models
Nils Niggemann, Johannes Reuther, Björn Sbierski
We employ a recently developed variant of the functional renormalization group method for spin systems, the so-called pseudo Majorana functional renormalization group, to investiga…
Tilted disordered Weyl semimetals
Maximilian Trescher, Björn Sbierski, Piet W. Brouwer +1
Although Lorentz invariance forbids the presence of a term that tilts the energy-momentum relation in the Weyl Hamiltonian, a tilted dispersion is not forbidden and, in fact, gener…
Quantum transport in Dirac materials: signatures of tilted and anisotropic Dirac and Weyl cones
Maximilian Trescher, Björn Sbierski, Piet W. Brouwer +1
We calculate conductance and noise for quantum transport at the nodal point for arbitrarily tilted and anisotropic Dirac or Weyl cones. Tilted and anisotropic dispersions are gener…
