Phonon-driven tuning of exchange interactions in Y3Fe5O12
Kunihiko Yamauchi, Tamio Oguchi
Yttrium iron garnet (Y3Fe5O12) is a prototypical ferrimagnetic insulator widely used in spin-wave and magnonic devices owing to its extremely low magnetic damping and long magnon p…
Spin-degenerate bulk bands and topological surface states associated with Dirac nodal lines in RuO2
T. Osumi, K. Yamauchi, S. Souma +13
Altermagnets are a novel platform to realize exotic electromagnetic properties distinct from those of conventional ferromagnets and antiferromagnets. We report results of micro-foc…
Accelerating crystal structure search through active learning with neural networks for rapid relaxations
Stefaan S. P. Hessmann, Kristof T. Schütt, Niklas W. A. Gebauer +3
Global optimization of crystal compositions is a significant yet computationally intensive method to identify stable structures within chemical space. The specific physical propert…
Universal Role of Combined Symmetry for the Protection of the Dirac Cone in Antiferromagnetic Topological Insulators
Asuka Honma, Noriyuki Kabeya, Seigo Souma +13
Antiferromagnetic topological insulators (AF TIs) are predicted to exhibit exotic physical properties such as gigantic optical and topological magnetoelectric responses. While a ke…
Antiferromagnetic topological insulator with selectively gapped Dirac cones
A. Honma, D. Takane, S. Souma +14
Antiferromagnetic (AF) topological materials offer a fertile ground to explore a variety of quantum phenomena such as axion magnetoelectric dynamics and chiral Majorana fermions. T…
Conversion of a conventional superconductor into a topological superconductor by topological proximity effect
C. X. Trang, N. Shimamura, K. Nakayama +9
Realization of topological superconductors (TSCs) hosting Majorana fermions is a central challenge in condensed-matter physics. One approach is to use the superconducting proximity…
Direct Observation of Nonequivalent Fermi-Arc States of Opposite Surfaces in Noncentrosymmetric Weyl Semimetal NbP
S. Souma, Zhiwei Wang, H. Kotaka +9
We have performed high-resolution angle-resolved photoemission spectroscopy (ARPES) on noncentrosymmetric Weyl semimetal candidate NbP, and determined the electronic states of both…
