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…
Magnetic Taylor-Proudman constraint explains the flows into the Tangent Cylinder
Alban Pothérat, Kélig Aujogue, François Debray
Tangent Cylinders (TCs) have shaped our understanding of planetary dynamos and liquid cores. The Taylor-Proudman Constraint (TPC) due to planetary rotation creates these imaginary…

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.…
Incommensurate antiferromagnetism in UTe2 under pressure
W. Knafo, T. Thebault, P. Manuel +10
The discovery of multiple superconducting phases in UTe2 boosted research on correlated-electron physics. This heavy-fermion paramagnet was rapidly identified as a reference compou…
Unveiling the double-peak structure of quantum oscillations in the specific heat
Zhuo Yang, Benoit Fauque, Toshihiro Nomura +12
Quantum oscillation phenomenon is an essential tool to understand the electronic structure of quantum matter. Here we report a systematic study of quantum oscillations in the elect…
Adiabatic demagnetization refrigeration to mK temperatures with the distorted square lattice magnet NaYbGeO
U. Arjun, K. M. Ranjith, A. Jesche +3
We report the synthesis, characterization, low-temperature magnetic, and thermodynamic measurements of the novel milli-Kelvin adiabatic demagnetization refrigeration (mK-ADR) candi…
High-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Yuhao Ye, Akiyoshi Yamada, Yuto Kinoshita +16
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twi…
VO under hydrostatic pressure: Isostructural phase transition close to a critical end-point
P. Bouvier, L. Bussmann, D. Machon +4
The high-pressure behavior of monoclinic VO is revisited by a combination of Raman spectroscopy and X-ray diffraction on a single crystal under hydrostatic conditions at room t…
Raman scattering excitation in monolayers of semiconducting transition metal dichalcogenides
M. Zinkiewicz, M. Grzeszczyk, T. Kazimierczuk +10
Raman scattering excitation (RSE) is an experimental technique in which the spectrum is made up by sweeping the excitation energy when the detection energy is fixed. We study the l…
Characterisation of the waveplate associated to layers in interferential mirrors
J. Agil, B. Letourneur, S. George +2
In this paper, first we present a review of experimental data corresponding to phase retardation per reflection of interferential mirrors. Then, we report our new measurements on b…
Longitudinal spin fluctuations driving field-reinforced superconductivity in UTe
Yo Tokunaga, Hironori Sakai, Shinsaku Kambe +10
Our measurements of Te NMR relaxations reveal an enhancement of electronic spin fluctuations above T, leading to their divergence in the vicinity of the meta…
