Phase-Controlled Majorana Zero Modes in Altermagnetic Topological-Insulator Josephson Junctions
Hao Dong, Xun-Jiang Luo, Xiao-Hong Pan +1
We exploit facet-dependent Andreev phase shifts to control topological superconductivity with a phase bias in a three-dimensional altermagnetic topological-insulator Josephson junc…
Majorana zero modes in twisted transition metal dichalcogenides homobilayers
Xun-Jiang Luo, Wen-Xuan Qiu, Fengcheng Wu
Semiconductor moiré superlattices provide a highly tunable platform to study the interplay between electron correlation and band topology. For example, the generalized Kane-Mele-Hu…
Deterministic topological quantum gates for Majorana qubits without ancillary modes
Su-Qi Zhang, Jian-Song Hong, Yuan Xue +4
The realization of quantum gates in topological quantum computation still confronts significant challenges in both fundamental and practical aspects. Here, we propose a determinist…
Interaction-driven topological phase diagram of twisted bilayer MoTe
Wen-Xuan Qiu, Bohao Li, Xun-Jiang Luo +1
Twisted bilayer MoTe is a promising platform to investigate the interplay between band topology and many-body interaction. We present a theoretical study of its interaction-dri…
Generalization of Benalcazar-Bernevig-Hughes model to arbitrary dimensions
Xun-Jiang Luo, Fengcheng Wu
The Benalcazar-Bernevig-Hughes (BBH) model [Science 357, 61 (2017)], featuring bulk quadrupole moment, edge dipole moments, and corner states, is a paradigm of both higher-order to…
Symmetric Wannier states and tight-binding model for quantum spin Hall bands in AB-stacked MoTe/WSe
Xun-Jiang Luo, Minxuan Wang, Fengcheng Wu
Motivated by the observation of topological states in AB-stacked MoTe/WSe, we construct the symmetry-adapted Wannier states and tight-binding model for the quantum spin Hal…
Higher-order topological phases emerging from the Su-Schrieffer-Heeger stacking
Xun-Jiang Luo, Xiao-Hong Pan, Chao-Xing Liu +1
In this work, we develop a systematical approach of constructing and classifying the model Hamiltonians for two-dimensional (2D) higher-order topological phase with corner zero ene…
Braiding higher-order Majorana corner states through their spin degree of freedom
Xiao-Hong Pan, Xun-Jiang Luo, Jin-Hua Gao +1
In this work, we study the spin texture of a class of higher-order topological superconductors (HOTSC) and show how it can be used to detect and braid Majorana corner modes (MCMs).…
Controllable Majorana vortex states in iron-based superconducting nanowires
Chuang Li, Xun-Jiang Luo, Li Chen +3
There has been experimental evidence for the Majorana zero modes (MZMs) in solid state systems, which are building blocks for potential topological quantum computing. It is importa…
Higher-order topological superconductors based on weak topological insulators
Xun-Jiang Luo, Xiao-Hong Pan, Xin Liu
High-order topological phases host robust boundary states at the boundary of the boundary, which can be interpreted from their boundary topology. In this work, considering the inte…
Braiding Majorana zero modes in spin space: from worldline to worldribbon
Xun-Jiang Luo, Ying-Ping He, Ting Fung Jeffrey Poon +2
We propose a scheme to braid Majorana zero modes (MZMs) through steering the spin degree of freedom, without moving, measuring, or more generically fusing the modes. For a spinful…
