Curvature-induced nonlinear anomalous Hall effect in thin magnetic shells
Maria Teresa Mercaldo, Mario Cuoco, Carmine Ortix
Optoelectronic and nonlinear transport experiments probe the quantum geometric tensor of Bloch states, whose real and imaginary components -- the quantum metric and the Berry curva…
Topological piezomagnetic effect in two-dimensional Dirac quadrupole altermagnets
H. Radhakrishnan, B. Bell, C. Ortix +1
Altermagnets provide a natural platform for studying and exploiting piezomagnetism. In this paper, we introduce a class of insulating altermagnets in two dimensions (2D) referred t…
Layer dipole magnetoelectric polarizability of antiferromagnetic bilayers
H. Radhakrishnan, C. Ortix, J. W. F. Venderbos
In this paper we study magnetoelectric effects in two-dimensional magnetic bilayers and introduce the notion of a layer dipole magnetoelectric polarizability. This magnetoelectric…
Topological spin multipolization and linear magnetoelectric coupling in two-dimensional antiferromagnets
Jörn W. F. Venderbos, Paola Gentile, Carmine Ortix
In this paper we predict that the magnetoelectric response of two-dimensional (2D) antiferromagnets is determined by the topology of the ground state. This topological magnetoelect…
