Revealing altermagnetic Fermi surfaces with two Kondo impurities
Qiong Qin, Toshihiro Sato, Marcin Raczkowski +3
Motivated by recent advances in the study of altermagnetism, or unconventional magnetism, and in the realization and manipulation of two-impurity Kondo physics in real materials, w…
Feynman paradox in a spherical axion insulator
Anastasiia Chyzhykova, Jeroen van den Brink, Flavio S. Nogueira
We show that a small charged probe near a spherical topological insulator causes the latter to rotate around a symmetry axis defined by the center of the sphere and the position of…
Real critical exponents from the -expansion in an interacting model with non-Hermitian anisotropy
Eduard Naichuk, Jeroen van den Brink, Flavio S. Nogueira
In quantum optics and condensed matter physics non-Hermitian phenomena are often studied under the assumption of an open physical system. However, there are examples of intrinsical…
Magnon topology driven by altermagnetism
Subhankar Khatua, Volodymyr P. Kravchuk, Kostiantyn V. Yershov +1
Altermagnets present a class of fully compensated collinear magnetic order, where the two sublattices are not related merely by time-reversal combined with lattice translation or i…
Antiferromagnetism and spin excitations in a two-dimensional non-Hermitian Hatano-Nelson flux model
Eduard Naichuk, Ilya M. Eremin, Jeroen van den Brink +1
The one-dimensional Hatano-Nelson model with non-reciprocal hoppings is a prominent example of a relatively simple non-Hermitian quantum-mechanical system, which allows to study va…
Orbital order in classical models of transition-metal compounds
Zohar Nussinov, Marek Biskup, Lincoln Chayes +1
We study the classical 120-degree and related orbital models. These are the classical limits of quantum models which describe the interactions among orbitals of transition-metal co…
