One-dimensional magnetism in synthetic Pauflerite, -VOSO
Diana Lucia Quintero-Castro, Gøran J. Nilsen, Katrin Meier-Kirchner +7
We have synthesized single-crystal samples of -VOSO and fully characterized their magnetic properties. Our magnetic susceptibility, high field magnetization and powder inela…
Enhanced eigenvector sensitivity and algebraic classification of sublattice-symmetric exceptional points
Kang Yang, Ipsita Mandal
Exceptional points (EPs) are degeneracy of non-Hermitian Hamiltonians, at which the eigenvalues, along with their eigenvectors, coalesce. Their orders are given by the Jordan decom…
Floquet transmission in Weyl/multi-Weyl and nodal-line semimetals through a time-periodic potential well
Sandip Bera, Sajid Sekh, Ipsita Mandal
In mesoscopic physics, the application of a time-periodic drive leads to novel transport behaviour, which is absent in the static regimes. Here we consider a quantum pumping protoc…
Boundary logarithmic corrections to the dynamical correlation functions of one-dimensional spin-1/2 chains
Imke Schneider, Ipsita Mandal, Polina Matveeva +2
The asymptotic dynamical correlation functions in one-dimensional spin chains are described by power-laws. The corresponding exponents characterize different bulk and boundary crit…
Magneto-optical conductivity in the type-I and type-II phases of Weyl/multi-Weyl semimetals
Shivam Yadav, Sajid Sekh, Ipsita Mandal
Magneto-optical conductivity is a very widely studied transport coefficient, useful to understand and characterize the behaviour of materials under magnetic fields. Using the Kubo…
Magneto-transport signatures in periodically-driven Weyl and multi-Weyl semimetals
Shivam Yadav, Serena Fazzini, Ipsita Mandal
We investigate the influence of a time-periodic driving (for example, by shining circularly polarized light) on three-dimensional Weyl and multi-Weyl semimetals, in the planar Hall…
