Continuous Tuning of the Charge-Phase Uncertainty in a Josephson Junction
Irena Padniuk, Xianzhe Zeng, Juan Carlos Cuevas +3
Quantum mechanics constrains conjugate observables from being simultaneously measurable with arbitrary precision. In a Josephson junction, these are the transferred electric charge…
Enhancing the Energy Resolution in Scanning Tunneling Microscopy: from dynamical Coulomb blockade to cavity quantum electrodynamics
Xianzhe Zeng, Janis Siebrecht, Haonan Huang +4
Scanning tunneling microscopy and spectroscopy have become indispensable tools for probing condensed matter at atomic length scales, yet achieving ultimate energy resolution remain…
Nanoscale electric-field imaging based on a quantum sensor and its charge-state control under ambient condition
Ke Bian, Wentian Zheng, Xianzhe Zeng +6
Nitrogen-vacancy (NV) centers in diamond can be used as quantum sensors to image the magnetic field with nanoscale resolution. However, nanoscale electric-field mapping has not bee…
Barkhausen effect in the first order structural phase transition in type-II Weyl semimetal MoTe2
Chuanwu Cao, Xin Liu, Xiao Ren +7
We report the first observation of the non-magnetic Barkhausen effect in van der Waals layered crystals, specifically, between the Td and 1T' phases in type-II Weyl semimetal MoTe2…
