Nonlinear photoconductivities and quantum geometry of chiral multifold fermions
Hsiu-Chuan Hsu, Jhih-Shih You, Junyeong Ahn +1
Chiral multifold fermions are quasi-particles that appear only in chiral crystals such as transition metal silicides in the cubic B20 structure (i.e., the CoSi family), and they ma…
Disorder effects on triple-point fermions
Hsiu-Chuan Hsu, Ion Cosma Fulga, Jhih-Shih You
The stability of three-dimensional relativistic semimetals to disorder has recently attracted great attention, but the effect of disorder remains elusive for multifold fermions, th…
Supermetal-insulator transition in a non-Hermitian network model
Hui Liu, Jhih-Shih You, Shinsei Ryu +1
We study a non-Hermitian and non-unitary version of the two-dimensional Chalker-Coddington network model with balanced gain and loss. This model belongs to the class D^dagger with…
Infinite Berry Curvature of Weyl Fermi Arcs
Dennis Wawrzik, Jhih-Shih You, Jorge I. Facio +2
We show that Weyl Fermi arcs are generically accompanied by a divergence of the surface Berry curvature scaling as , where is the distance to a hot-line in the surface B…
Creating Weyl nodes and controlling their energy by magnetization rotation
Madhav Prasad Ghimire, Jorge I. Facio, Jhih-Shih You +6
As they do not rely on the presence of any crystal symmetry, Weyl nodes are robust topological features of an electronic structure that can occur at any momentum and energy. Acting…
Topological Nonlinear Anomalous Nersnt Effect in Strained Transition Metal Dichalcogenides
Xiao-Qin Yu, Zhen-Gang Zhu, Jhih-Shih You +2
We theoretically analyze the non-linear anomalous Nernst effect as the second-order response of temperature gradient by using the semiclassical framework of electron dynamics. We f…
Strongly enhanced Berry dipole at topological phase transitions in BiTeI
Jorge I. Facio, Dmitri Efremov, Klaus Koepernik +3
Transitions between topologically distinct electronic states have been predicted in different classes of materials and observed in some. A major goal is the identification of measu…
Berry curvature dipole current in transition metal dichalcogenides family
Jhih-Shih You, Shiang Fang, Su-Yang Xu +2
We study the quantum nonlinear Hall effect in two-dimensional materials with time-reversal symmetry. When only one mirror line exists, a transverse charge current occurs in second-…
Collective resonances near zero energy induced by a point defect in bilayer graphene
Jhih-Shih You, Jian-Ming Tang, Wen-Min Huang
Intrinsic defects give rise to scattering processes governing the transport properties of mesoscopic systems. We investigate analytically and numerically the local density of state…
Electron-spin to Phonon Coupling in Graphene Decorated with Heavy Adatoms
Jhih-Shih You, Daw-Wei Wang, Miguel A. Cazalilla
The naturally weak spin-orbit coupling in Graphene can be largely enhanced by adatom deposition (e.g. Weeks et al. Phys. Rev. X 1, 021001 (2011)). However, the dynamics of the adat…
Relativistic ferromagnetic magnon at the zigzag edge of graphene
Jhih-Shih You, Wen-Min Huang, Hsiu-Hau Lin
We study the spin-wave excitations near the zigzag edge of graphene. It is rather interesting that we obtain a single branch of relativistic ferromagnetic magnon due to the presenc…
