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…
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…
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,…
Ferroelectrically Switchable Half-Quantized Hall Effect
M. U. Muzaffar, Kai-Zhi Bai, Wei Qin +5
Integrating ferroelectricity, antiferromagnetism, and topological quantum transport within a single material is rare, but crucial for developing next-generation quantum devices. He…
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…
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…
Half Quantum Mirror Hall Effect
Bo Fu, Kai-Zhi Bai, Shun-Qing Shen
We report the discovery of the half-quantized mirror Hall effect, a novel quantum-anomaly induced by mirror symmetry in a strong topological insulator (TI) film. These films are kn…
