Localization of cold atom within half-wavelength domain
Shun-Cai Zhao, Xin Li, Ping Yang
Simulating the cold atom with a three-level quantum system interacting with two orthogonal standing-wave fields, the localization within half-wavelength domain in the x-y…
Dual peaks evoluting into single-peak for sub-wavelength 2-D atom localization in a V-type atomic system
Shun-Cai Zhao, Xin Li, Ping Yang
The atom localization of a V-type atomic system is discussed by the detunings associated with the probe and the two orthogonal standing-wave fields, and by the spontaneously genera…
Topmetal-M: a novel pixel sensor for compact tracking applications
Weiping Ren, Wei Zhou, Bihui You +22
The Topmetal-M is a large area pixel sensor (18 mm * 23 mm) prototype fabricated in a new 130 nm high-resistivity CMOS process in 2019. It contains 400 rows * 512 columns square pi…
Probing the Tavis-Cummings level splitting with intermediate-scale superconducting circuits
Ping Yang, Jan David Brehm, Juha Leppäkangas +7
We demonstrate the local control of up to eight two-level systems interacting strongly with a microwave cavity. Following calibration, the frequency of each individual two-level sy…
Resonance inversion in a superconducting cavity coupled to artificial atoms and a microwave background
Juha Leppäkangas, Jan David Brehm, Ping Yang +4
We demonstrate how heating of an environment can invert the line shape of a driven cavity. We consider a superconducting coplanar cavity coupled to multiple artificial atoms. The m…

Adiabatic approximation in the ultrastrong-coupling regime of a system consisting of an oscillator and two qubits
Ping Yang, Zhi-Ming Zhang
We present a system composed of two flux qubits and a transmission-line resonator. Instead of using the rotating wave approximation (RWA), we analyse the system by the adiabatical…
