Contemporary Insights into Electronic Structure and Microscopic Transport in Nodal-Line Semimetals
Ashutosh S. Wadge, Pardeep K. Tanwar, Giuseppe Cuono +1
Topological semimetals have emerged as an important class of quantum materials with novel electronic responses and unconventional transport phenomena. Among them, nodal-line semime…
Charge and spin photogalvanic effects in the p-wave magnet NiI2
Giuseppe Cuono, Srdjan Stavric, Javier Sivianes Castano +4
NiI2 is an exotic van der Waals material in which a noncollinear spin spiral breaks spatial inversion symmetry without sizeable structural distortion, generating improper ferroelec…
Interplay between Relativistic Spin-Momentum Locking and Breaking of Inversion Symmetry: conditions for p-wave magnetism
Amar Fakhredine, Giuseppe Cuono, Jan Skolimowski +2
We investigate the interplay between relativistic spin-momentum locking arising from altermagnetism and various forms of inversion symmetry breaking. Depending on the symmetry brea…
Dirac edge states as signature of two-dimensional altermagnetic topological crystalline phase
Raghottam M. Sattigeri, Xujia Gong, Amar Fakhredine +2
Two-dimensional (2D) metallic altermagnets present exciting opportunities for both fundamental research and practical innovations. Their ability to enhance tunneling magnetoresista…
Staggered Dzyaloshinskii-Moriya and canting angle in centrosymmetric altermagnetic and ferromagnetic phases: influence on the anomalous Hall effect and Weyl points
Mathews Benny, Xujia Gong, Kamil Jamroszczyk +5
We present a simple methodology to compute the anomalous Hall conductivity (AHC) as a function of the canting angles in ferromagnets and altermagnets, starting from a nonmagnetic H…
Bulk photovoltaic effect in MoSe and Janus MoSSe sliding ferroelectrics
Roumita Roy, Giuseppe Cuono, Silvia Picozzi
We present a first-principles study of the nonlinear optical properties of sliding ferroelectric bilayers based on MoSe and Janus MoSSe. Two Janus configurations are considered…
