Ultrasound Evidence for a Low-Temperature Anomaly Inside the Superconducting State of 4Hb-TaS
Yongwei Li, Dmitri V. Efremov, Paul Leask +7
We report low-temperature ultrasound measurements on single crystals of the layered van der Waals superconductor 4Hb-TaS. Specific heat and ac magnetic susceptibility show a sh…
Physical properties of new delafossite triangular-lattice compounds TlErSe and TlTmSe
Bastian Rubrecht, Ellen Häußler, Mirtha Pillaca +7
Delafossite compounds containing rare-earth ions have been proven to be an ideal platform to investigate frustrated magnetic ground states. Here, we discuss two triangular-lattice…
Single-Q and Double-Q magnetic orders: A Theoretical Analysis of Inelastic Neutron Scattering in a Centrosymmetric Structure
Artem O. Nosenko, Dmitri V. Efremov
Recent discoveries of multi-\textbf{Q} magnetic structures in centrosymmetric compounds have stimulated growing interest in their microscopic origin and observable properties. Here…
Semiclassical transport with Berry curvature: Chambers formula and applications to systems with Fermi surface topological transitions
Emmanouil K. Kokkinis, Garry Goldstein, Dmitry Efremov +1
Starting with general semiclassical equations of motion for electrons in the presence of electric and magnetic fields, we extend the Chambers formula to include in addition to a ma…
Close proximity of FeSe to a magnetic quantum critical point as revealed by high-resolution SR measurements
V. Grinenko, R. Sarkar, P. Materne +12
A nematic transition preceding a long-range spin density wave antiferromagnetic phase is a common feature of many Fe based superconductors. However, in the FeSe system with a nemat…
The fate of interaction-driven topological insulators under disorder
Jing Wang, Carmine Ortix, Jeroen van den Brink +1
We analyze the effect of disorder on the weak-coupling instabilities of quadratic band crossing point (QBCP) in two-dimensional Fermi systems, which, in the clean limit, display in…
