Phase Drift Monitoring for Tone Tracking Readout of Superconducting Microwave Resonators

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Max Silva-Feaver, Zeeshan Ahmed, Kam Arnold, Josef C. Frisch, John Groh | Summary: A number of modern millimeter, sub-millimeter, and far-infrared detectors are read out using superconducting microwave (1-10GHz) resonators. The main detector technologies are Transition Edge Sensors, read out using Microwave SQUID Multiplexers ($mu$mux) and Microwave […]

A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

Posted by dbos Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker, Clarence L. Chang, Yen-Yung Chang | Summary: The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called “quasiparticle poisoning". Both superconducting qubits and low […]

Production of brain-derived neurotrophic factor gates plasticity in developing visual cortex

Posted by klaurent UCSF

Kavli Affiliate: Michael Stryker | Authors: Megumi Kaneko and Michael P Stryker | Summary: Abstract We have previously shown that recovery of visual responses to a deprived eye during the critical period in mouse primary visual cortex (V1) requires both export of mRNA encoding brain derived neurotrophic factor (BDNF) to the dendrites of cortical cells […]

Thermal Testing for Cryogenic CMB Instrument Optical Design

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: D. C. Goldfinger, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: Observations of the Cosmic Microwave Background rely on cryogenic instrumentation with cold detectors, readout, and optics providing the low noise performance and instrumental stability required to make more sensitive measurements. It is […]

Modeling Dust Production, Growth, and Destruction in Reionization-Era Galaxies with the CROC Simulations: Methods and Parameter Exploration

Posted by klaurent Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Clarke J. Esmerian, Nickolay Y. Gnedin, , , | Summary: We introduce a model for the explicit evolution of interstellar dust in a cosmological galaxy formation simulation. We post-process a simulation from the Cosmic Reionization on Computers project (CROC, Gnedin 2014), integrating an ordinary differential equation […]

Exploring $boldsymbol{2+2}$ Answers to $boldsymbol{3+1}$ Questions

Posted by klaurent Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Jonathan J. Heckman, Austin Joyce, Jeremy Sakstein, Mark Trodden, | Summary: We explore potential uses of physics formulated in Kleinian (i.e., $2+2$) signature spacetimes as a tool for understanding properties of physics in Lorentzian (i.e., $3+1$) signature. Much as Euclidean (i.e., $4+0$) signature quantities can be used […]
