Signatures of pressure-enhanced helimagnetic order in van der Waals multiferroic NiI
Connor A. Occhialini, Luiz G. P. Martins, Qian Song +10
The van der Waals (vdW) type-II multiferroic NiI has emerged as a candidate for exploring non-collinear magnetism and magnetoelectric effects in the 2D limit. Frustrated intral…
Effects of Pressure on the Electronic and Magnetic Properties of Bulk NiI
Jesse Kapeghian, Danila Amoroso, Connor A. Occhialini +10
Transition metal dihalides have recently garnered interest in the context of two-dimensional van der Waals magnets as their underlying geometrically frustrated triangular lattice l…
Mode-coupling theory of lattice dynamics for classical and quantum crystals
Aloïs Castellano, J. P. Alvarinhas Batista, Matthieu J. Verstraete
The dynamical properties of nuclei, carried by the concept of phonon quasiparticles (QP), are central to the field of condensed matter. While the harmonic approximation can reprodu…
