Pressure-induced structural transitions triggering dimensional crossover in lithium purple bronze Li0.9M6O17
M. K. Tran, A. Akrap, J. Levallois +7
At ambient pressure, lithium molybdenum purple bronze (Li0.9Mo6O17) is a quasi-one dimensional solid in which the anisotropic crystal structure and the linear dispersion of the und…
Suppressed magnetic circular dichroism and valley-selective magneto-absorption due to the effective mass anisotropy in bismuth
Pieter J. de Visser, Julien Levallois, Michaël K. Tran +6
We have measured the far-infrared reflectivity and Kerr angle spectra on a high-quality crystal of pure semimetallic bismuth as a function of magnetic field, from which we extract…
Temperature-dependent ellipsometry measurements of partial Coulomb energy in superconducting cuprates
J. Levallois, M. K. Tran, D. Pouliot +8
We performed an experimental study of the temperature and doping dependence of the energy-loss function of the bilayer and trilayer Bi-cuprate family. The primary aim is to obtain…
Fermi liquid behavior of the in-plane resistivity in the pseudogap state of YBa_2Cu_4O_8
Cyril Proust, B. Vignolle, J. Levallois +2
Our knowledge of the ground state of underdoped hole-doped cuprates has evolved considerably over the last few years. There is now compelling evidence that inside the pseudogap pha…
Magneto-optical Kramers-Kronig analysis
Julien Levallois, Ievgeniia Nedoliuk, Iris Crassee +1
We describe a simple magneto-optical experiment and introduce a magneto-optical Kramers-Kronig analysis (MOKKA) that together allow extracting the complex dielectric function for l…
Magnetoplasmon resonances in polycrystalline bismuth as seen via terahertz spectroscopy
Julien Levallois, Piotr Chudzinski, Jason N. Hancock +2
We report the magnetic field-dependent far-infrared reflectivity of polycrystalline bismuth. We observe four distinct absorptions that we attribute to magnetoplasmon resonances, wh…
