Thermal transport and low-temperature specific heat in 4Hb-TaS
M. Gillig, I. Mangel, I. Feldman +4
We investigate the low-energy excitation spectrum of the van der Waals heterostructure superconductor 4Hb-TaS using ultra-low-temperature specific-heat and thermal-conductivity…
Spin-chiral electron-phonon coupling in metallic strontium titanate
N. Somun, L. RogiÄ, I. Khayr +12
Electron-phonon coupling (EPC) - the interaction between conduction electrons and quantized atomic vibrations - plays a central role in condensed matter physics and determines some…
Electrical and thermal magnetotransport in altermagnetic CrSb
Sajal Naduvile Thadathil, Christoph Müller, Reza Firouzmandi +20
Chromium antimonide has emerged as a key material platform for studying altermagnetism because of its simple binary composition, high Néel temperature, and semimetallic electronic…
Observation of resistive switching and diode effect in the conductivity of TiTe2 point contacts
O. E. Kvitnitskaya, L. Harnagea, O. D. Feia +3
We measured the I(V) and dV/dI(V) characteristics of TiTe2-based point contacts (PCs) from room to helium temperatures. Features indicating the emergence of a charge density wave (…
Fermi surface evolution in Weyl semimetal t-PtBi probed by transverse transport properties
F. Caglieris, M. Ceccardi, D. Efremov +8
The combination of non-trivial topology and superconductivity opens to novel quantum devices. The discovery of intrinsic materials where such properties appear together represents…
Chiral anomaly in the Weyl semimetal TaRhTe
M. Behnami, D. V. Efremov, S. Aswartham +10
TaRhTe is a type-IIWeyl semimetal, exhibiting fourWeyl points in proximity to the Fermi level. In this article, we report our results of a systematic study of longitudinal magn…
