Unusual magneto-transport from Si-square nets in topological semimetal HfSiS
Nitesh Kumar, Kaustuv Manna, Yanpeng Qi +5
The class of topological semimetals comprises a large pool of compounds. Together they provide a wide platform to realize exotic quasiparticles for example Dirac, nodal line Dirac…
Topological quantum phase transition and superconductivity induced by pressure in the bismuth tellurohalide BiTeI
Yanpeng Qi, Wujun Shi, Pavel G. Naumov +8
A pressure-induced topological quantum phase transition has been theoretically predicted for the semiconductor BiTeI with giant Rashba spin splitting. In this work, the evolution o…
Compensated ferrimagnetic tetragonal Heusler thin films for antiferromagnetic spintronics
Roshnee Sahoo, Lukas Wollmann, Susanne Selle +9
In recent years, antiferromagnetic spintronics has received much attention since ideal antiferromagnets do not produce stray fields and are much more stable to external magnetic fi…
Multiple Dirac cones at the surface of the topological metal LaBi
Jayita Nayak, Shu-Chun Wu, Nitesh Kumar +8
The rare-earth monopnictide LaBi exhibits exotic magneto-transport properties including an extremely large and anisotropic magnetoresistance. Experimental evidence for topological…
Anomalous Hall effect in Weyl semimetal half Heusler compounds RPtBi (R = Gd and Nd)
Chandra Shekhar, Nitesh Kumar, V. Grinenko +17
Topological materials ranging from topological insulators to Weyl and Dirac semimetals form one of the most exciting current fields in condensed-matter research. Many half-Heusler…
Pressure-driven Superconductivity in Transition-metal Pentatelluride HfTe5
Yanpeng Qi, Wujun Shi, Pavel G. Naumov +8
Layered transition-metal tellurides have attracted considerable attention because of their rich physics; for example, tungsten ditelluride WTe2 exhibits extremely large magnetoresi…
