Thermomechanical two-mode squeezing in an ultrahigh membrane resonator
Y. S. Patil, S. Chakram, L. Chang +1
We realize a nondegenerate parametric amplifier in an ultrahigh mechanical membrane resonator and demonstrate two-mode thermomechanical noise squeezing. Our measurements are ac…
The Afterglow of GRB 130427A from 1 to 10^16 GHz
D. A. Perley, S. B. Cenko, A. Corsi +31
We present multiwavelength observations of the afterglow of GRB 130427A, the brightest (in total fluence) gamma-ray burst of the past 29 years. Optical spectroscopy from Gemini-Nor…
Graphene quantum dots for valley-based quantum computing: A feasibility study
G. Y. Wu, N. -Y. Lue, L. Chang
At the center of quantum computing1 realization is the physical implementation of qubits - two-state quantum information units. The rise of graphene2 has opened a new door to the i…
Emergence of pion parton distributions
Z. -F. Cui, M. Ding, J. M. Morgado +7
Supposing only that there is an effective charge which defines an evolution scheme for parton distribution functions (DFs) that is all-orders exact, strict lower and upper bounds o…
Extending Field Limits in Nanoscale Magnetic Imaging with Metamaterial-inspired Magnetic Flux Concentrators
A. Barrera, E. Fourneau, T. Pirottin +14
Many nanoscale magnetic imaging techniques are constrained by the maximum magnetic field that can be applied during measurements, due to geometrical limitations or interactions wit…
Spectropolarimetry of Fraunhofer lines in local upper solar atmosphere
Z. Q. Qu, L. Chang, G. T. Dun +6
Spectropolarimetric results of Fraunhofer lines between 516.3nm and 532.6nm are presented in local upper solar chromosphere, transition zone and inner corona below a height of abou…
