Geometry-induced Monopole Magnetic Field and Quantum Spin Hall Effect
Yong-Long Wang, Hao Zhao, Hua Jiang +2
The geometric effects of two-dimensional curved systems have been an interesting topic for a long time. A Möbius surface is specifically considered. For a relativistic particle con…
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…
Network model for higher-order topological phases
Hui Liu, Selma Franca, Ali G. Moghaddam +2
We introduce a two-dimensional network model that realizes a higher-order topological phase (HOTP). We find that in the HOTP the bulk and boundaries of the system are gapped, and a…
Anomalous levitation and annihilation in Floquet topological insulators
Hui Liu, Ion Cosma Fulga, Janos K. Asboth
Anderson localization in two-dimensional topological insulators takes place via the so-called levitation and pair annihilation process. As disorder is increased, extended bulk stat…
Effective dynamics for a spin-1/2 particle constrained to a space curve in an electric and magnetic field
Guo-Hua Liang, Yong-Long Wang, Meng-Yun Lai +3
We consider the dynamics of a spin-1/2 particle constrained to move in an arbitrary space curve with an external electric and magnetic field applied. With the aid of gauge theory,…
Geometry induced quantum Hall effect and Hall viscosity
Yong-Long Wang, Hong-Shi Zong, Hui Liu +1
For a particle confined to the two-dimensional helical surface embedded in four-dimensional (4D) Euclidean space, the effective Hamiltonian is deduced in the thin-layer quantizatio…
