Element-Specific Visualization of Layer-Parity and Twist-Dependent Magnetism in CrSBr
Aalok Tiwari, Shubhada Patil, Ravi Kumar Bandapelli +16
Van der Waals (vdW) based antiferromagnets (AFMs) are an ideal platform for probing and understanding thickness- and twist-angle-dependent emergent spin phenomena. However, element…
Enabling Electrical Readout of Néel vector reversal in a van der Waals Antiferromagnet
Raghvendra Posti, Ravi Kumar Bandepalli, Wenhao Liu +14
Owing to its robustness against external perturbations and intrinsically ultrafast dynamics, the Néel vector in antiferromagnets (AFMs) can enable the development of next-generati…
Non-local low energy neutral excitations in a strongly disordered triangular Mott magnet CrSeBr
Wenhao Liu, Dechen Zhang, Yuanqi Lyu +13
Understanding if low-energy excitations can remain itinerant in the presence of strong disorder remains a central challenge in frustrated quantum magnets, where disorder is general…
Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
Highly Efficient Second/Third Harmonic Generation in van der Waals Layered Material AgScP2S6 with Anisotropic Polarization and Temperature Dependence
Mohamed Yaseen Noor, Ryan Siebenaller, Wenhao Liu +12
Single-crystal X-ray diffraction and nonlinear optical measurements, especially second- and third-harmonic generation (SHG/THG) are comprehensively investigated for the van der Waa…
Observation of robust one-dimensional edge channels in a three-dimensional quantum spin Hall insulator
Shuikang Yu, Junze Deng, Wenhao Liu +13
Topologically protected edge channels show prospects for quantum devices. They have been found experimentally in two-dimensional (2D) quantum spin Hall insulators (QSHIs), weak top…
