A method to compute derivatives of functions of large complex matrices
M. Puhr, P. V. Buividovich
A recently developed numerical method for the calculation of derivatives of functions of general complex matrices, which can also be combined with implicit matrix function approxim…
Chiral magnetic conductivity in an interacting lattice model of parity-breaking Weyl semimetal
P. V. Buividovich, M. Puhr, S. N. Valgushev
We report on the mean-field study of the Chiral Magnetic Effect (CME) in static magnetic fields within a simple model of a parity-breaking Weyl semimetal given by the lattice Wilso…
A Method to Calculate Conserved Currents and Fermionic Force for the Lanczos Approximation to the Overlap Dirac Operator
M. Puhr, P. V. Buividovich
The overlap Dirac operator obeys the Ginsparg-Wilson equation and offers a possibility to introduce chiral symmetry on the lattice. Evaluating the overlap operator is numerically v…
A lattice mean-field study of the phase diagram of interacting parity-breaking Weyl semimetals
P. V. Buividovich, M. Puhr
We perform a mean-field study of the phase diagram of interacting Weyl semimetals with broken parity, that is, with different densities of right- and left-handed quasiparticles. As…
