TSTG II: Projected Hartree-Fock Study of Twisted Symmetric Trilayer Graphene
Fang Xie, Nicolas Regnault, Dumitru Călugăru +2
The Hamiltonian of the magic-angle twisted symmetric trilayer graphene (TSTG) can be decomposed into a TBG-like flat band Hamiltonian and a high-velocity Dirac fermion Hamiltonian.…
Chern-Simons Theory and Wilson Loops in the Brillouin Zone
Biao Lian, Cumrun Vafa, Farzan Vafa +1
Berry connection is conventionally defined as a static gauge field in the Brillouin zone. Here we show that for three-dimensional (3d) time-reversal invariant superconductors, a ge…
Spontaneous Spin Textures in Dipolar Spinor Condensates: A Dirac String Gas Approach
Biao Lian
We study the spontaneous spin textures induced by magnetic dipole-dipole interaction in ferromagnetic spinor condensates under various trap geometries. At the mean-field level, we…
Electrically Tunable Magnetism in Magnetic Topological Insulators
Jing Wang, Biao Lian, Shou-Cheng Zhang
The external controllability of the magnetic properties in topological insulators would be important both for fundamental and practical interests. Here we predict the electric-fiel…
Broadband Linear-Dichroic Photodetector in a Black Phosphorus Vertical p-n Junction
Hongtao Yuan, Xiaoge Liu, Farzaneh Afshinmanesh +12
The ability to detect light over a broad spectral range is central for practical optoelectronic applications, and has been successfully demonstrated with photodetectors of two-dime…
Generation and Electric Control of Spin-Coupled Valley Current in WSe2
Hongtao Yuan, Xinqiang Wang, Biao Lian +8
The valley degree of freedom in layered transition-metal dichalcogenides (MX2) provides the opportunity to extend functionalities of novel spintronics and valleytronics devices. Du…
