Entwined lattice of atoms and anionic electrons in layered electride LaCl
Songyuan Geng, Xin Wang, Jianqi Zhong +14
Controlling the lattice geometry that governs electronic structure is a central theme in condensed-matter physics, yet in crystalline solids this geometry is usually fixed by the a…
Disentangling bulk and surface states in the electronic structure of PtBi(0001)
Stefanie Suzanne Brinkman, Xin Liang Tan, Anders Christian Mathisen +13
Recent reports of surface-localized topological superconductivity in trigonal PtBi highlight the importance of understanding its surface electronic structure. We investigate th…
Fermiology and spin polarization of topological surface states in PtBi
Anders Christian Mathisen, Xin Liang Tan, Stefanie Suzanne Brinkman +12
Layered PtBi is a candidate for topological superconductivity arising in Fermi-arc surface states. Using spin- and angle-resolved photoemission spectroscopy, we demonstrate tha…
Discerning ground state and photoemission-induced spin textures in altermagnetic -MnTe
D. A. Usanov, S. W. D'Souza, A. Dal Din +12
The recently discovered class of altermagnets provide a physical realization of an unconventional compensated magnetic phase with a higher partial-wave type of ordering, reminiscen…
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…
Hidden Moiré Topology of Low-Symmetry Weyl Surfaces
Cong Li, Zhilong Yang, Hongxiong Liu +11
Topological materials are defined by the correspondence between bulk topology and boundary states, yet this correspondence becomes enigmatic on low-symmetry surfaces where bulk and…
Probing enhanced superconductivity in van der Waals polytypes of VTaS
Wojciech R. Pudelko, Huanlong Liu, Francesco Petocchi +15
Layered transition metal dichalcogenides (TMDs) stabilize in multiple structural forms with profoundly distinct and exotic electronic phases. Interfacing different layer types is a…
Topological Weyl Altermagnetism in CrSb
Cong Li, Mengli Hu, Zhilin Li +12
Altermagnets constitute a novel, third fundamental class of collinear magnetic ordered materials, alongside with ferro- and antiferromagnets. They share with conventional antiferro…
Observation of Giant Spin Splitting and d-wave Spin Texture in Room Temperature Altermagnet RuO2
Zihan Lin, Dong Chen, Wenlong Lu +9
Recently, a novel magnetic phase called altermagnetism has been proposed, ushering in a third distinct magnetic phase beyond ferromagnetism and antiferromagnetism. It is expected t…
Non-Hermitian Boundary in a Surface Selective Reconstructed Magnetic Weyl Semimetal
Cong Li, Yang Wang, Jianfeng Zhang +11
Non-Hermitian physics, studying systems described by non-Hermitian Hamiltonians, reveals unique phenomena not present in Hermitian systems. Unlike Hermitian systems, non-Hermitian…
Disorder Driven Non-Anderson Transition in a Weyl Semimetal
Cong Li, Yang Wang, Jianfeng Zhang +11
For several decades, it was widely believed that a non-interacting disordered electronic system could only undergo an Anderson metal-insulator transition due to Anderson localizati…
Influence of oxygen-coordination number on the electronic structure of single-layer La-based cuprates
M. Horio, X. Peiao, M. Miyamoto +12
We present an angle-resolved photoemission spectroscopy study of the single-layer T*-type structured cuprate SmLaSrCuO with unique five-fold pyramidal oxygen coordi…
Ferrimagnetic Regulation of Weyl Fermions in a Noncentrosymmetric Magnetic Weyl Semimetal
Cong Li, Jianfeng Zhang, Yang Wang +14
The study of interaction between electromagnetism and elementary particles is a long-standing topic in physics. Likewise, the connection between particle physics and emergent pheno…
What's knot to like? Observation of a linked loop quantum state
Ilya Belopolski, Guoqing Chang, Tyler A. Cochran +22
Quantum phases can be classified by topological invariants, which take on discrete values capturing global information about the quantum state. Over the past decades, these invaria…
Revealing the Heavy Quasiparticles in the Heavy-Fermion Superconductor CeCu2Si2
Zhongzheng Wu, Yuan Fang, Hang Su +11
The superconducting order parameter of the first heavy-fermion superconductor CeCu2Si2 is currently under debate. A key ingredient to understand its superconductivity and physical…
