Nonreciprocal and Exotic Radiative Transfer in Type-I Magnetic Weyl Semimetals
… heat transfer, we include the effects of Fermi arc surface states, a hallmark of Weyl semimetals. We show that—in contrast to far-field radiative heat transfer—Fermi arc surface states play a significant role in the near-field and that the heat flux between the two Weyl semimetals can be …

Modelling of Berry phase and Fermi-level topologies for emergent quantum phenomena prediction in selected solid state systems
… Berry curvature, surface state spectra, and Fermi arc patterns via WannierTools. To probe QPTs in SrSi2, we employ the Quantum Lattice environment to simulate a renormalized graphene lattice, mapping analogies between external perturbations and topological responses in both systems.

Renormalization for insulating states of matter
… Green function. In comparison to the Fermi arc structure, which is intrinsic to cuperate phenomenology, we suggest that the suppression of the spectral weight at the back side of the arc is a consequence of composite excitations, arising from dynamical mixing. The second topic we study …

DEGENERATE SECOND ORDER NONLINEAR OPTICAL SPECTROSCOPY OF CHIRAL WEYL SEMIMETALS
… effect (CPGE) in RhSi deriving from topological Fermi arc states. While the magnitude of the CPGE response broadly matched theoretical predictions, the data also exhibit an inexplicably high degree of symmetry in the response as a function of incoming polarization in both CPGE and LPGE channels. …

Quantum Transport and Electric-Field Effects in Layered Topological Semimetals and Magnetic Materials
… in ZrSiSe indicate that the phonon modes and Fermi surface area are unchanged by current annealing. </p> <p>Through current annealing, we had access to suitable device quality, hence could investigate topological semimetals extensively. We studied Shubnikov de Haas oscillations focused on the …
