Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics
Advanced Science, EarlyView.The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Degenerate parabolic stochastic partial differential equations
Stochastic Processes and their Applications, 2013 Dans cette thèse, on considère des problèmes issus de l'analyse d'EDP stochastiques paraboliques non-dégénérées et dégénérées, de lois de conservation hyperboliques stochastiques, et d'EDS avec coefficients continus. Dans une première partie, on s'intéresse à des EDPS paraboliques dégénérées- on adapte les notions de formulation et de solutions ...

d‐Wave Fermi Surface Instability in the Nematic Phase of Two Monolayer FeSe/SrTiO3
Advanced Science, EarlyView.Angle‐resolved photoemission spectroscopy reveals a d‐wave nematic order in two‐monolayer FeSe/SrTiO3, showing degenerate dxz/dyz bands at Γ but a pronounced splitting at M. This momentum‐dependent anisotropy identifies the nematicity as a d‐wave Fermi surface (Pomeranchuk) instability, highlighting 2D FeSe as a model platform to explore the interplay ...

Ultrafast Nonlinear Dynamics of Indium Tin Oxide Nanocrystals Probed via Fieldoscopy
Advanced Science, EarlyView.The ultrafast nonlinear dynamics of indium tin oxide nanocrystals excited with 1 MHz, 10 fs pulses, at their localized surface plasmon frequency, and near their epsilon‐near‐zero wavelength is probed via fieldoscopy. The study demonstrates fluence‐dependent switching behavior, advancing the understanding of high‐speed optical modulation in plasmonic ...

Inverse problem of determining the coefficients in a degenerate parabolic equation
Electronic Journal of Differential Equations, 2014 We consider the inverse problem of identifying the time-dependent coefficients in a degenerate parabolic equation. The conditions of existence and uniqueness of the classical solution to this problem are established. We investigate the case of weak
