Ferroaxial magnets: time-reversal-even mirror symmetry violation from spin order
Hikaru Watanabe, Yue Yu, Jin Matsuda +2
We investigate ferroaxial magnets, a new class of spin-order-driven multiferroic magnets in which magnetic ordering induces mirror-symmetry breaking while preserving both time-reve…
Parity and time-reversal invariant Ising spin ordering
Yue Yu, Jin Matsuda, Hikaru Watanabe +2
The interplay of antiferromagnetic order, momentum-dependent Bloch spin-splitting, time-reversal (T), and parity (P) symmetries in non-relativistic systems has emerged as a central…
Phase Field Study of Exchange Coupling of Hard/Soft Ferrite on Magnetic Permeability
Xinyu Xu, Wenqin Yue, Yueli Yu +2
Effective modulation of magnetic permeability plays a vital role in the development of high-performance inductors. Here, phase-field simulations of hard/soft ferrite composites (Ba…
Origin of sublattice particle-hole asymmetry in monolayer FeSe superconductors
Mercè Roig, Kazi Ranjibul Islam, Basu Dev Oli +7
In iron-based superconductors, the two Fe atoms in the unit cell are typically related by crystal symmetries; therefore, we expect no intra-unit cell variations in the superconduct…
Emergent continuous symmetry and ground-state factorization induced by long-range interactions
Yue Yu, Myung-Joong Hwang
The spontaneous breaking of a symmetry typically gives rise to emergent excitations possessing the same symmetry with a renormalized mass. Contrary to this conventional wisdo…
Symmetry-required Orbital Selectivity in Monolayer FeSe
Mercè Roig, Qiang Zou, Basu Dev Oli +6
Orbital-selective correlations have been observed to play an important role in Fe-based superconductors. Here, in contrast to previous site-local Mott transition-based origins, we…
