Quantum Logic Enhanced Sensing in Solid-State Spin Ensembles
Nithya Arunkumar, Kevin S. Olsson, Jner Tzern Oon +7
We demonstrate quantum logic enhanced sensitivity for a macroscopic ensemble of solid-state, hybrid two-qubit sensors. We achieve a factor of 30 improvement in signal-to-noise rati…
Massive thermal fluctuation of massless graphene electrons
Hosang Yoon, Donhee Ham
Whereas thermal current noise in typical conductors is proportional to temperature , in graphene exhibits a nonlinear dependence…
Measurement of Collective Dynamical Mass of Dirac Fermions in Graphene
Hosang Yoon, Carlos Forsythe, Lei Wang +6
Individual electrons in graphene behave as massless quasiparticles. In surprising twist, it is inferred from plasmonic investigations that collectively excited graphene electrons m…
Two-Path Solid-State Interferometry Using Ultra-Subwavelength 2D Plasmonic Waves
Kitty Y. M. Yeung, Hosang Yoon, William Andress +3
We report an on-chip solid-state Mach-Zehnder interferometer operating on two-dimensional (2D) plasmonic waves at microwave frequencies. Two plasmonic paths are defined with GaAs/A…
Phase Diffusion and Lamb-Shift-Like Spectrum Shift in Classical Oscillators
Xiaofeng Li, Wenjiang Zhu, Donhee Ham
The phase diffusion in a self-sustained oscillator, which produces oscillator's spectral linewidth, is inherently governed by a nonlinear Langevin equation. Over past 40 years, the…
Integrated Cell Manipulation Systems
Hakho Lee, Yong Liu, Donhee Ham +1
A new type of microfluidic system for biological cell manipulation, a CMOS/microfluidic hybrid, is demonstrated. The hybrid system starts with a custom-designed CMOS (complementary…
