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…
Altermagnetism and its induced higher-order topology on the Lieb lattice
Xingmin Huo, Xingchuan Zhu, Chang-An Li +4
Altermagnetism (AM) has brought renewed attention to the Lieb lattice. Here, we broaden the scope of altermagnetic models on the Lieb lattice by using a general scheme based on spi…
Exceptional Andreev spectrum and supercurrent in p-wave non-Hermitian Josephson junctions
Chang-An Li, Björn Trauzettel
We investigate the spectrum of Andreev bound states and supercurrent in a -wave non-Hermitian Josephson junction (NHJJ) in one dimension. The studied NHJJ is composed of two top…
Marginal Metals and Kosterlitz-Thouless Type Phase Transition in Disordered Altermagnets
Chang-An Li, Bo Fu, Huaiming Guo +2
Altermagnetism, a recently discovered magnetic phase characterized by spin-split bands without net magnetization, has emerged as promising platform for novel physics and potential…
Non-Hermitian Quantum Fractals
Junsong Sun, Chang-An Li, Qingyang Guo +5
The first quantum fractal discovered in physics is the Hofstadter butterfly. It stems from large external magnetic fields. We discover instead a new class of non-Hermitian quantum…
