Tip-Tuned Renormalization-Group Spectroscopy Unmasks a False-positive Topological Superconducting Vortex
Zhenhua Zhu, Qun Zhu, Yong-Wei Wang +6
Clean, nonsplit vortex zero-bias peaks (ZBPs) can be misinterpreted as Majorana zero modes (MZMs), making static scanning tunneling microscopy intrinsically ambiguous. Here we use…
Charge Density Wave Driven Topological Phase Transition in Vortices
Zhenhua Zhu, Ziqiang Wang, Dong E. Liu
The interplay between charge density waves (CDWs) and superconductivity is a central theme in quantum materials, yet how CDW phase textures govern vortex topology remains poorly un…
Topological surface states revealed by the Zeeman effect in superconducting UTe2
Zhen Zhu, Hans Christiansen, Yudi Huang +11
Intrinsic topological superconductors with protected boundary modes obeying non-Abelian statistics constitute a vanishingly small class of quantum materials. A defining spectroscop…
Intertwined Charge Stripes and Majorana Zero Modes in An Iron-Based Superconductor
Yu Liu, Li-Xuan Wei, Qiang-Jun Cheng +12
In type-II superconductors, magnetic fields modulate the amplitude and phase of the superconducting order parameter, forming quantized vortices where superconductivity is locally s…
Detecting entanglement with transport measurement in weakly interacting and fluctuating systems
Zhenhua Zhu, Gu Zhang, Dong E. Liu
Measuring entanglement entropy in interacting, multipartite systems remains a significant experimental challenge. We address this challenge by developing a protocol to measure von…
