Study of the symmetry of electronic system of the Weyl semimetal GdBiPt using rotational anisotropy of second harmonic generation
Simon Daneau, Richard Leonelli, Andrea D. Bianchi
The half-Heusler compound GdBiPt orders antiferromagnetically around K which implies breaking the time reversal symmetry as well as the translational symmetry. T…
Second-Order Raman Scattering in Exfoliated Black Phosphorus
Alexandre Favron, Félix Antoine Goudreault, Vincent Gosselin +7
Second-order Raman scattering has been extensively studied in carbon-based nanomaterials, \emph{e.g.} nanotube and graphene, because it activates normally forbidden Raman modes tha…
Probing Hyperbolic and Surface Phonon-Polaritons in 2D materials using Raman Spectroscopy
A. Bergeron, C. Gradziel, R. Leonelli +1
The hyperbolic dispersion relation of phonon-polaritons (PhPol) provides high-momentum states, highly directional propagation, subdiffractional confinement, large optical density o…
Lattice vibrations and dynamic disorder in two-dimensional hybrid lead-halide perovskites
Vlad Alexandru Dragomir, Stefanie Neutzner, Claudio Quarti +7
By means of non-resonant Raman spectroscopy and density functional theory calculations, we measure and assign the vibrational spectrum of two distinct two-dimensional lead-iodide p…
Stable biexcitons in two-dimensional metal-halide perovskites with strong dynamic lattice disorder
Félix Thouin, Stefanie Neutzner, Daniele Cortecchia +8
With strongly bound and stable excitons at room temperature, single-layer, two-dimensional organic-inorganic hybrid perovskites are viable semiconductors for light-emitting quantum…
Incoherent population mixing contributions to phase-modulation two-dimensional coherent excitation spectra
Pascal Grégoire, Ajay Ram Srimath Kandada, Eleonora Vella +2
We present theoretical and experimental results showing the effects of incoherent population mixing on two-dimensional (2D) coherent excitation spectra that are measured via a time…
