Evolution of quantum criticality in underdoped cuprates
Changshuai Lan, Chengyu Yan, Yihang Li +7
Quantum criticality, with both static and dynamic information of the system intrinsically encoded in characteristic length scales, serves as one of the most sensitive and universal…
Vortex-driven periodic and aperiodic magnetoresistance oscillations in cuprates
Changshuai Lan, Chuanwen Zhao, Xin Yi +5
The study of the interaction between superconductivity and charge ordering is helpful to resolve the pairing mechanism in high-temperature superconductors. Recently, several resist…
Interference Effects in a Tunable Quantum Point Contact Integrated with an Electronic Cavity
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
We show experimentally how quantum interference can be produced using an integrated quantum system comprising an arch-shaped short quantum wire (or quantum point contact, QPC) of 1…
Incipient singlet-triplet states in a hybrid mesoscopic system
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
In the present work we provide an easily accessible way to achieve the singlet-triplet Kondo effect in a hybrid system consisting of a quantum point contact (QPC) coupled to an ele…
A Symmetric Superconducting Dome Hosts Non-Fermi Liquid Behavior at Optimal Doping in MoS2
Qiao Chen, Chengyu Yan, Dino Novko +9
The similarities between the phase diagrams of ionic liquid-gated transition metal dichalcogenides (TMDCs) and high-temperature superconductors have garnered considerable interest…
Dual-mode superconducting diode effect enabled by in-plane and out-of-plane magnetic field
Chengyu Yan, Huai Guan, Zhenyu Zhang +6
The discovery of the superconducting diode effect (SDE) has been cherished as a milestone in developing superconducting electronics. Tremendous efforts are being dedicated to reali…
