Optically driven ultrafast lattice contraction in a topological crystalline insulator
M. H. Berntsen, W. Chen, D. Phuyal +9
The ability to dynamically control topological order remains a central challenge in the exploration of quantum materials. Here, we investigate the lattice and electronic response o…
Floquet dressing of bulk metallic bands in 2H-NbSe2
Cong Li, Qirui Cui, Maciej Dendzik +6
Floquet dressing offers a route to controlling electronic states through periodic optical driving. Its realization in solids has centred primarily on topological-insulator surface…
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…
Wafer-Scale Single-Crystalline Monolayer Graphene
Johanna Huhtasaari, Joyal Jain Palakulam, Awse Salha +11
Producing large-area single-crystalline graphene is key to realizing its full potential in advanced applications, including twistronics. Yet, controlling graphene growth kinetics t…
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…
Contrasting electron-phonon interaction between electron- and hole-doped cuprates
Qinda Guo, Ke-Jun Xu, Magnus H. Berntsen +15
Spin- and charge-lattice interactions are potential key factors in the microscopic mechanism of high-temperature superconductivity in cuprates. Although both interactions can drama…
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…
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…
Anomalous normal state gap in an electron-doped cuprate
Ke-Jun Xu, Junfeng He, Su-Di Chen +11
In the underdoped n-type cuprate Nd2-xCexCuO4, long-ranged antiferromagnetic order reconstructs the Fermi surface, resulting in a putative antiferromagnetic metal with small pocket…
A reinvestigation of the giant Rashba-split states on Bi-covered Si(111)
M. H. Berntsen, O. Götberg, O. Tjernberg
We study the electronic and spin structures of the giant Rashba-split surface states of the Bi/Si(111)-()R30 trimer phase by means of spin- and angle-reso…
