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…
Berry phase polarization and orbital magnetization responses of insulators: Formulas for generalized polarizabilities and their application
J. W. F. Venderbos
Condensed matter physics is often concerned with determining the response of a solid to an external stimulus. This paper revisits and extends the microscopic formalism for calculat…
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…
Evidence for chiral superconductivity on a silicon surface
F. Ming, X. Wu, C. Chen +9
Sn adatoms on a Si(111) substrate with 1/3 monolayer coverage form a two-dimensional triangular adatom lattice with one unpaired electron per site and an antiferromagnetic Mott ins…
Translation symmetry-enriched toric code insulator
Pok Man Tam, Jörn W. F. Venderbos, Charles L. Kane
We introduce a two-dimensional electronic insulator that possesses a toric code topological order enriched by translation symmetry. This state can be realized from disordering a we…
