Anomalous Hall transport by optically injected isospin degree of freedom in Dirac semimetal thin film
Yuta Murotani, Natsuki Kanda, Tomohiro Fujimoto +7
Chirality of massless fermions emergent in condensed matter is a key to understand their characteristic behavior as well as to exploit their functionality. However, chiral nature o…
Enhanced Dirac node separation in strained Cd3As2 topological semimetal
Gauthier Krizman, Joaquin Bermejo-Ortiz, Manik Goyal +7
In topological semimetals, nodes appear at symmetry points in the Brillouin zone as a result of band inversion, and yield quasi-relativistic massless fermions at low energies. Cd3A…
Absence of signatures of Weyl orbits in the thickness dependence of quantum transport in cadmium arsenide
Luca Galletti, Timo Schumann, David A. Kealhofer +2
In a Weyl orbit, the Fermi arc surface states on opposite surfaces of the topological semimetal are connected through the bulk Weyl or Dirac nodes. Having a real-space component, t…
Two-Dimensional Dirac Fermions in Thin Films of Cd3As2
Luca Galletti, Timo Schumann, Omor F. Shoron +4
Two-dimensional states in confined thin films of the three-dimensional Dirac semimetal Cd3As2 are probed by transport and capacitance measurements under applied magnetic and electr…
Observation of the quantum Hall effect in confined films of the three-dimensional Dirac semimetal Cd3As2
Timo Schumann, Luca Galletti, David A. Kealhofer +3
The magnetotransport properties of epitaxial films of Cd3As2, a paradigm three-dimensional Dirac semimetal, are investigated. We show that an energy gap opens in the bulk electroni…
Negative magnetoresistance due to conductivity fluctuations in films of the topological semimetal Cd3As2
Timo Schumann, Manik Goyal, David A. Kealhofer +1
Recently discovered Dirac and Weyl semimetals display unusual magnetoresistance phenomena, including a large, non-saturating, linear transverse magnetoresistance and a negative lon…
