We present the RF Quantum Upconverter (RQU) and describe its application to quantum metrology of electromagnetic modes between dc very high frequency band (VHF) (<a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mrow><a:mo>≲</a:mo><a:mn>300</a:mn></a:mrow></a:math> MHz). The RQU uses a Josephson interferometer made up superconducting loops junctions implement parametric interaction low-frequency mode (between VHF) in microwave C Band (<b:math...
We propose a method using solid state detectors with directional sensitivity to dark matter interactions detect low-mass weakly interacting massive particles (WIMPs) originating from galactic sources. In spite of large body literature for high-mass WIMP sensitivity, no available technique exists cover WIMPs in the mass range $<1\text{ }\text{ }\mathrm{GeV}/{c}^{2}$. argue that single-electron-resolution semiconductor allow once properly calibrated. examine commonly used material response...
The proposed Mitchell Institute Neutrino Experiment at Reactor (MINER) experiment the Nuclear Science Center Texas A&M University will search for coherent elastic neutrino-nucleus scattering within close proximity (about 2 meters) of a 1 MW TRIGA nuclear reactor core using low threshold, cryogenic germanium and silicon detectors. Given Standard Model cross section process experimental to reactor, as many 5 20 events/kg/day are expected. We discuss status preliminary measurements characterize...
We propose to use the defect creation energy loss in commonly used high physics solid state detectors as a tool statistically identify dark matter signal from background. simulate process of using density functional theory and molecular dynamics methods calculate corresponding expected spectra. show that phonon-mediated detectors, due convolved with interaction results significant change spectra for common detector materials. With recent progress towards $\sim$10 eV threshold low-mass...
We describe the RF Quantum Upconverter (RQU) and its application to quantum metrology of electromagnetic modes between dc Very High Frequency band (VHF) ($\lesssim$300MHz). The RQU uses a Josephson interferometer made up superconducting loops junctions implement parametric interaction low-frequency mode (between VHF) in microwave C Band ($\sim$ 5GHz), analogous radiation pressure mechanical cavity optomechanics. can operate as quantum-limited op-amp, or use protocols from optomechanics...
The purpose of this experiment is to observe the oblique propagation electrons through germanium by exciting a point source charge carriers with focused laser pulse on one face crystal. After are drifted crystal uniform electric field, pattern density arriving opposite mapped and used reconstruct trajectories electrons. These measurements will verify in detail Monte Carlo analysis utilized Cryogenic Dark Matter Search model transport high-purity detectors, including both electron...
