Sign control of photocurrents by spin-group-symmetry breaking in altermagnetic insulators
Gastón Blatter, Xiao Zhang, Jeroen van den Brink +2
Controlling physical responses through symmetry breaking is a central paradigm in quantum materials, enabling novel functionalities. Here we determine the effects of spin-group-sym…
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…
Unconventional Josephson effects in {\it PT}-symmetric antiferromagnetic bilayers
Jin-Xin Hu, Mengli Hu, Ying-Ming Xie +1
We propose that unconventional Josephson effects can typically emerge in {\it PT}-symmetric antiferromagnetic (AFM) bilayer systems. When proximitized by a conventional superconduc…
Extreme Strain Controlled Correlated Metal-Insulator Transition in the Altermagnet CrSb
Cong Li, Mengli Hu, Jianfeng Zhang +14
Correlated flat bands and altermagnetism are two important directions in quantum materials, centred respectively on interaction-dominated phases and symmetry-enforced spin-textured…
Spin Hall and Edelstein Effects in Novel Chiral Noncollinear Altermagnets
Mengli Hu, Oleg Janson, Claudia Felser +3
Altermagnets are a newly discovered class of magnetic phases that combine the spin polarization behavior of ferromagnetic band structures with the vanishing net magnetization chara…
