Magnetic electron collimation in three-dimensional semi-metals
Xiangwei Huang, Carsten Putzke, Chunyu Guo +6
While electrons moving perpendicular to a magnetic field are confined to cyclotron orbits, they can move freely parallel to the field. This simple fact leads to complex current flo…
Field-angle dependence of sound velocity in the Weyl semimetal TaAs
F. Laliberté, F. Bélanger, N. L. Nair +5
The elastic modulus of a single crystal of the Weyl semimetal TaAs was investigated by measuring relative changes in the sound velocity under application of a magnetic fie…
Resonance-enhanced optical nonlinearity in the Weyl semimetal TaAs
Shreyas Patankar, Liang Wu, Baozhu Lu +10
While all media can exhibit first-order conductivity describing current linearly proportional to electric field, , the second-order conductivity, , relating current to…
Inducing superconductivity in Weyl semi-metal microstructures by selective ion sputtering
Maja D. Bachmann, Nityan Nair, Felix Flicker +7
By introducing a superconducting gap in Weyl- or Dirac semi-metals, the superconducting state inherits the non-trivial topology of their electronic structure. As a result, Weyl sup…
Giant anisotropic nonlinear optical response in transition metal monopnictide Weyl semimetals
Liang Wu, S. Patankar, T. Morimoto +6
Although Weyl fermions have proven elusive in high-energy physics, their existence as emergent quasiparticles has been predicted in certain crystalline solids in which either inver…
Magnetic torque anomaly in the quantum limit of the Weyl semi-metal NbAs
Philip J. W. Moll, Andrew C. Potter, Brad Ramshaw +9
Electrons in materials with linear dispersion behave as massless Weyl- or Dirac-quasiparticles, and continue to intrigue physicists due to their close resemblance to elusive ultra-…
