First-Order Topological FFLO Transition and Superconducting Diode Sign Reversal in Altermagnetic Nanowires
Bo Fu, Kaizhi Bai, Chang-An Li +1
Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state conventionally emerges via a second-order phase transition driven by finite magnetization. Here we show that a spin-orbit-coupled nano…
Ferroelectrically Switchable Chirality in Topological Superconductivity
Kai-Zhi Bai, Bo Fu, Shun-Qing Shen
The interplay between ferroelectricity, magnetism, and superconductivity provides a rich platform for discovering novel quantum phenomena. Here, we develop an effective theory and…
Nearly semi-elliptic relation between the minimal conductivity and Hall conductivity in unpaired Dirac fermions
Bo Fu, Kai-Zhi Bai, Shi-Hao Bi +1
Electric conductivities may reveal the topological and magnetic properties of band structures in solids, especially for two-dimensional unpaired Dirac fermions. In this work, we ev…
Parity Anomalous Semimetal with Minimal Conductivity Induced by an In-Plane Magnetic Field
Binbin Wang, Jiayuan Hu, Bo Fu +5
The interplay between topological materials and local symmetry breaking gives rise to diverse topological quantum phenomena. A notable example is the parity anomalous semimetal (PA…
Dirac Fermions and Topological Phases in Magnetic Topological Insulator Films
Kai-Zhi Bai, Bo Fu, Shun-Qing Shen
We develop a Dirac fermion theory for topological phases in magnetic topological insulator films. The theory is based on exact solutions of the energies and the wave functions for…
Prediction of High-Temperature Half Quantum Anomalous Hall Effect in a Semi-magnetic Topological Insulator of MnBiTe/SbTe
M. U. Muzaffar, Kai-Zhi Bai, Wei Qin +6
The classic Thouless-Kohmoto-Nightingale-Nijs theorem dictates that a single electron band of a lattice can only harbor an integer quantum Hall conductance as a multiple of e^2/2h,…
