Direct Evidence of Unconventional Superconductivity in Doped Kagome system RVSb
Avior Almoalem, Yuqing Xing, Iksu Jang +7
The superconducting pairing symmetry of kagome metals remains a central unresolved question largely because phase-sensitive experiments capable of distinguishing between different…
Discovery of an odd-parity f-wave charge order in a kagome metal
Jiangchang Zheng, Caiyun Chen, Ruiqin Fu +13
The spontaneous breaking of symmetries is a cornerstone of physics, defining the phases of matter from the cosmological scale to the quantum realm. In condensed matter, electronic…
Interplay of competing bond-order and loop-current fluctuations as a possible mechanism for superconductivity in kagome metals
Asimpunya Mitra, Daniel J. Schultz, Yong Baek Kim
The pairing symmetry and underlying mechanism for superconducting state of AVSb (A=K, Rb, Cs) kagome metal has been a topic of intense investigation. In this work, we c…
Superconductivity in kagome metals due to soft loop-current fluctuations
Daniel J. Schultz, Grgur Palle, Asimpunya Mitra +3
We demonstrate that soft fluctuations of translation symmetry-breaking loop currents provide a mechanism for unconventional superconductivity in kagome metals that naturally addres…
Local spectroscopy of loop current order with individual magnetic atoms
Jiangchang Zheng, Caiyun Chen, Xu Zhang +16
Hidden ordered states--characterized by order parameters that elude conventional probes--pose a fundamental challenge for their identification in quantum materials. Recent experime…
Quantum Spin Liquids in Weak Mott Insulators with a Spin-Orbit Coupling
