Response functions for electric field induced two-dimensional nonlinear spectroscopy in a Kitaev magnet

W Brenig, O Krupnitska - Journal of Physics: Condensed Matter, 2024 - iopscience.iop.org
We study the dynamical response functions relevant for electric field induced two-
dimensional (2D) coherent nonlinear optical spectroscopy in a Kitaev magnet at finite …

Nonlinear optical responses in multiorbital topological superconductors

A Raj, A Postlewaite, S Chaudhary, GA Fiete - Physical Review B, 2024 - APS
We theoretically study first-and second-order optical responses in a transition-metal
dichalcogenide monolayer with distinct trivial, nodal, and time-reversal invariant topological …

Unveiling the Chiral States in Multi-Weyl Semimetals through Magneto-Optical Spectroscopy

S Saha, D Das, A Mawrie - arxiv preprint arxiv:2412.19132, 2024 - arxiv.org
This study investigates the transport parameters in multi-Weyl semimetals, focusing on their
magneto-optical properties and the role of chiral states. The tilting parameter is identified as …

Linear differential equation approach to the Loschmidt amplitude

M Vogl - arxiv preprint arxiv:2404.04921, 2024 - arxiv.org
The Loschmidt echo is a popular quantity that allows making predictions about the stability
of quantum states under time evolution. In our work, we present an approach that allows us …
