- Abstract summary: We study magneto-Raman spectra of exfoliated multilayer alpha-RuCl3 in out-of-plane magnetic fields of -6 T to 6 T at temperatures of 670 mK - 4 K.
While we saw no magnetic field driven transitions, the modes exhibit unexpected shifts in response to applied magnetic field that are above the uncertainties inferred from Bayesian analysis.
These shifts are consistent with the emergence of magnetostrictive interactions in exfoliated alpha-RuCl3 flakes.

- Abstract: Motivated by the possibility of an intermediate U(1) quantum spin liquid
phase in out-of-plane magnetic fields and enhanced magnetic fluctuations in
exfoliated {\alpha}-RuCl3 flakes, we study magneto-Raman spectra of exfoliated
multilayer {\alpha}-RuCl3 in out-of-plane magnetic fields of -6 T to 6 T at
temperatures of 670 mK - 4 K. While the literature currently suggests that bulk
{\alpha}-RuCl3 is in an antiferromagnetic zigzag phase with R3bar symmetry at
low temperature, we do not observe R3bar symmetry in exfoliated {\alpha}-RuCl3
at low temperatures. While we saw no magnetic field driven transitions, the
Raman modes exhibit unexpected stochastic shifts in response to applied
magnetic field that are above the uncertainties inferred from Bayesian
analysis. These stochastic shifts are consistent with the emergence of
magnetostrictive interactions in exfoliated {\alpha}-RuCl3.

We analyse the effect of a strong perpendicular magnetic field on an intersubband transition in a disordered doped quantum well strongly coupled to an optical cavity.
The magnetic field changes the lineshape of the intersubband optical transition due to the roughness of the interface of the quantum well from a Lorentzian to a Gaussian one.
