Beyond characteristic equations: A unified one-dimensional non-Bloch band theory via wavefunction data
Haoshu Li
Non-Hermitian systems play a central role in nonequilibrium physics, where determining the energy spectrum under open boundary conditions is a fundamental problem. Non-Bloch band t…
Magic of nonlocal geometric force: lighting up optical transition and transporting angular momentum by chiral phonons
Hao Chen, Haoshu Li, Lifa Zhang +1
We investigate the impact of the nonlocal geometric force -- arising from the molecular Berry curvature -- on the lattice dynamics of magnetic materials with broken time-reversal s…
Ultrafast switching of photoinduced phonon chirality in the antiferrochiral BPO crystal
Hao Chen, Hanyu Wang, Tingting Wang +4
In crystalline systems, chiral crystals cannot interconvert to their enantiomorph post-synthesis without undergoing melting-recrystallization processes. However, recent work indica…
Multifold Majorana corner modes arising from multiple pairs of helical edge states
Zhiwei Yin, Haoshu Li, Zhongbo Yan +1
Quantum spin Hall insulators with a pair of helical edge states and proximity-induced superconductivity have been shown to support second-order topological superconductors with Maj…
