Magnetic domain structure and domain wall bound states of topological semimetal EuB6
Qiang Li, Haiyang Ma, Xin Zhang +5
Electrically manipulating domain wall (DW) is at central in the field of spintronics. Magnetic Weyl semimetal (WSM) offers an additional knob for electric manipulation of DW by uti…
Electronic Origin of Half-metal to Semiconductor Transition and Colossal Magnetoresistance in Spinel HgCr2Se4
Aiji Liang, Zhilin Li, Shihao Zhang +13
Half-metals are ferromagnets hosting spin-polarized conducting carriers and crucial for spintronics applications. The chromium spinel HgCr2Se4 represents a unique type of half-meta…
Observation of Coexisting Dirac Bands and Moiré Flat Bands in Magic-Angle Twisted Trilayer Graphene
Yiwei Li, Shihao Zhang, Fanqiang Chen +17
Moiré superlattices that consist of two or more layers of two-dimensional materials stacked together with a small twist angle have emerged as a tunable platform to realize various…
Tunable intrinsic ferromagnetic topological phases in bulk van der Waals crystal MnSb6Te10
Xin Zhang, Shihao Zhang, Zhicheng Jiang +14
Intrinsic ferromagnetism is a crucial ingredient to realize quantum anomalous Hall effect in quasi two dimensional materials, thus the search of intrinsic ferromagnetic topological…
Multifunctional Antiferromagnetic Materials with Giant Piezomagnetism and Noncollinear Spin Current
Hai-Yang Ma, Mengli Hu, Nana Li +4
We propose a new type of spin-valley locking (SVL), named -paired SVL, in antiferromagnetic systems, which directly connects the spin/valley space with the real space,…
Experimental evidence for orbital magnetic moments generated by moiré-scale current loops in twisted bilayer graphene
Si-Yu Li, Yu Zhang, Ya-Ning Ren +3
A remarkable property of twisted bilayer graphene (TBG) with small twist angle is the presence of a well-defined and conserved low-energy valley degrees of freedom1, which can pote…
Observation of oscillatory relaxation in the Sn-terminated surface of epitaxial rock-salt SnSe topological crystalline insulator
Wencan Jin, Suresh Vishwanath, Jianpeng Liu +20
Topological crystalline insulators have been recently predicted and observed in rock-salt structure SnSe thin films. Previous studies have suggested that the Se-terminate…
Flux states and topological phases from spontaneous time-reversal symmetry breaking in CrSi(Ge)Te-based systems
Jianpeng Liu, Se Young Park, Kevin F. Garrity +1
We study adatom-covered single layers of CrSiTe and CrGeTe using first-principles calculations based on hybrid functionals. We find that the insulating ground state of a mo…
Topological nodal-line semimetals in alkaline-earth stannides, germanides and silicides
Huaqing Huang, Jianpeng Liu, David Vanderbilt +1
Based on first-principles calculations and an effective Hamiltonian analysis, we systematically investigate the electronic and topological properties of alkaline-earth compounds $A…
Tunable inverse topological heterostructure utilizing
Matthew Brahlek, Nikesh Koirala, Jianpeng Liu +6
In typical topological insulator (TI) systems the TI is bordered by a non-TI insulator, and the surrounding conventional insulators, including vacuum, are not generally treated as…
Topological phase transitions in (BiInSe and (BiSbSe
Jianpeng Liu, David Vanderbilt
We study the phase transition from a topological to a normal insulator with concentration in (BiInSe and (BiSbSe in the BiSe c…
