Optical conductivity and band gap in the double-Weyl candidate SrSi2 at ambient pressure
L. Z. Maulana, A. A. Tsirlin, E. Uykur +4
We probe the possible double-Weyl state in cubic SrSi2 using optical spectroscopy. The complex optical conductivity was measured in a frequency range from 70 to 22 000 cm-1 at temp…
Magneto-optical response of the Weyl semimetal NbAs: Experimental results and hyperbolic-band computations
S. Polatkan, E. Uykur, J. Wyzula +5
The magneto-optical properties of (001)-oriented NbAs single crystals have been studied in the spectral range from 5 to 150 meV and in magnetic fields of up to 13 T. A rich spectru…
Exchange gap in GdPtBi probed by magneto-optics
S. Polatkan, E. Uykur, I. Mohelsky +6
We measured the magneto-reflectivity spectra (4 - 90 meV, 0 - 16 T) of the triple-point semimetal GdPtBi and found them to demonstrate two unusual broad features emerging in field.…
Strong transient magnetic fields induced by THz-driven plasmons in graphene disks
Jeong Woo Han, Pavlo Sai, Dmytro But +10
Strong circularly polarized excitation opens up the possibility to generate and control effective magnetic fields in solid state systems, e.g., via the optical inverse Faraday effe…
Broadband optical conductivity of the chiral multifold semimetal PdGa
L. Z. Maulana, Z. Li, E. Uykur +5
We present an optical conductivity study of the multifold semimetal PdGa, performed in a broad spectral range (100 - 20000 cm-1; 12 meV - 2.5 eV) down to T = 10 K. The conductivity…
Two linear regimes in optical conductivity of a Type-I Weyl semimetal: the case of elemental tellurium
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
Employing high-pressure infrared spectroscopy we unveil the Weyl semimetal phase of elemental Te and its topological properties. The linear frequency dependence of the optical cond…
