Intrinsic translational symmetry-breaking charge stripes in underdoped iron pnictides
Qiang-Jun Cheng, Cong-Cong Lou, Yong-Wei Wang +4
Despite being well established in cuprates, an intrinsic translational symmetry-breaking charge order has not been clearly identified in iron-based superconductors. Using spectrosc…
Topological Semimetal Transport Modulated by Interstitial Fe in Ba(FeCo)_2$ Superconductors
Ze-Xian Deng, Qiang-Jun Cheng, Jing Jiang +14
Topological semimetals are renowned for exhibiting large, unsaturated magnetoresistance arising from ultrahigh carrier mobility and electron-hole compensation. However, such behavi…
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…
Atomic-scale imaging of electronic nematicity in ferropnictides
Qiang-Jun Cheng, Yong-Wei Wang, Ming-Qiang Ren +5
Electronic nematicity, a correlated state characterized by broken rotational symmetry, has been recognized as a ubiquitous feature intertwined with unconventional electron pairing…
Full-Gap Superconductivity in BaAs/Ferropnictide Heterostructures
Ming-Qiang Ren, Qiang-Jun Cheng, Hui-Hui He +10
Interfacial interactions often promote the emergence of unusual phenomena in two-dimensional systems, including high-temperature superconductivity. Here, we report the observation…
