Robust Signatures of Fragile Topology
Viktor Könye, Ihor Nimyi, Oleg Janson +3
Some topological phases of matter are called fragile. They do not generically host protected gapless boundary states and they can be trivialized by adding additional valence bands.…
Multipolar Piezoelectricity and Anisotropic Surface Transport in Alterelectrics
Amber Visser, Viktor Könye, Oleg Janson +3
Altermagnets are an emergent class of materials combining features of ferro- and antiferro-magnetic materials. They have spin-separated bands normally associated with ferromagnets,…
Magnetic-field tuning of the spin dynamics in the quasi-2D van der Waals antiferromagnet CuCrPS
Joyal John Abraham, Yaqian Guo, Yuliia Shemerliuk +14
The use of antiferromagnets in magnetoelectronic devices as counterparts of ferromagnets is a new, rapidly developing trend in spintronics that leverages antiferromagnetic (AFM) ma…
Fermi surface and topology of multiband superconductor BeAu
Riccardo Vocaturo, Klaus Koepernik, Dániel Varjas +3
The chiral material BeAu was recently identified as a multiband type-I superconductor with a critical temperature of 3.2 K. As a member of the B20 crystal family (space group $P2_1…
Generating ferro-spinetic polarizations in altermagnetic insulators
Toshihiro Sato, Mengli Hu, Ion Cosma Fulga +5
Altermagnets are a novel class of fully spin-compensated magnetic materials that nevertheless have spin-split electronic bands, offering novel perspectives for spintronics applicat…
Chiral magnetic excitations and domain textures of g-wave altermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Jorge I. Facio +5
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which opposite-spin sublattices are connected by a crystal rotation, causing their electronic iso-energ…
