Semi-Dirac Fermions in a Topological Metal
Yinming Shao, Seongphill Moon, A. N. Rudenko +14
Topological semimetals with massless Dirac and Weyl fermions represent the forefront of quantum materials research. In two dimensions (2D), a peculiar class of fermions that are ma…
Pressure tunable quantum anomalous Hall states in a topological antiferromagnet
Su Kong Chong, Chao Lei, Jie Li +8
Mechanical modulation of the lattice parameter can modify the electronic structure and manipulate the magnetic coupling of a material without introducing impurities. Inspired by su…
Evidence of Weyl Fermion Enhanced Thermal Conductivity Under Magnetic Fields in Antiferromagnetic Topological Insulator Mn(Bi(1-x)Sb(x))2Te4
Robert A. Robinson, Seng Huat Lee, Lujin Min +3
We report thermal conductivity and Seebeck effect measurements on Mn(Bi1-xSbx)2Te4 (MBST) with x = 0.26 under applied magnetic fields below 50 K. Our data shows clear indications o…
Large Violation of the Wiedemann Franz Law in Heusler, Ferromagnetic, Weyl Semimetal CoMnAl
Robert A. Robinson, Lujin Min, Seng Huat Lee +4
The Wiedemann-Franz (WF) law relates the electronic component of the thermal conductivity to the electrical conductivity in metals through the Lorenz number. The WF law has proven…
