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…
Suppression of Extrinsic Anomalous Hall Conductivity in Disordered Parity Anomalous Semimetal
Shi-Hao Bi, Bo Fu, Shun-Qing Shen
We present an analytical investigation of the extrinsic contributions to the anomalous Hall conductivity in the context of the half-quantized Hall effect observed in disordered par…
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…
Reinterpretation of chiral anomaly on a lattice
Huan-Wen Wang, Bo Fu, Shun-Qing Shen
The chiral anomaly is a quantum mechanical effect for massless Dirac fermions in both particle physics and condensed matter physics. Here we present a set of effective models for s…
Half-Quantized Hall Metal and Marginal Metal in Disordered Magnetic Topological Insulators
Shi-Hao Bi, Bo Fu, Shun-Qing Shen
A semimagnetic topological insulator -- a heterostructure combining a topological insulator with a ferromagnet -- exhibits a half-quantized Hall effect, characterized by a quantize…
Quantum Geometric Renormalization of the Hall Coefficient and Unconventional Hall Resistivity in ZrTe5
Huimin Xie, Bo Fu, Huan-Wen Wang +2
The anomalous Hall effect (AHE), conventionally associated with time-reversal symmetry breaking in ferromagnetic materials, has recently been observed in nonmagnetic topological ma…
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…
AMuLeT: Automated Design-Time Testing of Secure Speculation Countermeasures
Bo Fu, Leo Tenenbaum, David Adler +7
In recent years, several hardware-based countermeasures proposed to mitigate Spectre attacks have been shown to be insecure. To enable the development of effective secure speculati…
1/2 Z Topological Invariants and the Half Quantized Hall Effect
Bo Fu, Shun-Qing Shen
The half-quantized Hall phase represents a unique metallic or semi-metallic state of matter characterized by a fractional quantum Hall conductance, precisely half of an integer …
Disordered Parity Anomalous Semimetal
Shi-Hao Bi, Bo Fu, Shun-Qing Shen
The parity anomalous semimetal is a topological state of matter characterized by its semi-metallic nature and a quantum Hall conductance of one-half ( is the elementar…
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…
