Proton propagation in nuclei studied in the A dependence of the (e,e’p) reaction in the quasifree region
The A dependence of the (e,e’p) reaction in the quasifree region has been measured at an average Q2 of 0.33 (GeV/c)2 for targets of 12C, 27Al, 58Ni, and 181Ta. The outgoing proton kinetic energy was 180±30 MeV. By comparing ...
Measurement of 16O(γ,n)15O at medium energies
Exclusive differential cross sections for the 16O(γ,n)15O process have been measured for Eγ=150, 200, and 250 MeV and θL=49°, 59°, and 88°. This measurement is the first of its type to be reported for the energy region ...
Pulling Algorithm and Simulation
These files contain a script that produces the control parameters for motors necessary to fabricate an optical nanofiber with a user defined taper geometry. It also provides a simulation of the step-by-step geometry of the pull.
gfncalc Correlation function calculator
gfncalc is a C++ program that calculates second order normalized correlation functions from raw photon arrival times. It can read trigger pulses from another device to implement filtering. It features a simple command-line ...
False Vacuum at the Heart of Black Holes
It is proposed that the evaporation of black holes via Hawking radiation may conclude at densities and temperatures no higher than those invoked during the inflationary stage of common cosmological models, thus avoiding ...
Infinite Red-Shifts in General Relativity
(Cornell University Press, 1967)
The Oppenheimer-Snyder description of continued gravitational collapse is reformulated as a matching together of two familiar solutions of the Einstein gravitational equations. From one solution, the Friedmann cosmology ...
John A Wheeler and the recertification of GR as true physics
The physics life of John Archibald Wheeler is surveyed; the main emphasis is on the years 1953--1976 in Princeton where his activity primarily centered on Einstein's theory of gravitation, general relativity.
Magic Matter, the Computational Æther, and the Miner’s Canary
Several viewpoints are proposed with the aim of promoting further approaches to the numerical integration of Einstein's equations, especially its support of attempts to detect astrophysically significant gravitational ...
Fast Prediction and Evaluation of Gravitational Waveforms Using Surrogate Models
(American Physical Society, 2014-07-14)
We propose a solution to the problem of quickly and accurately predicting gravitational waveforms within any given physical model. The method is relevant for both real-time applications and more traditional scenarios where ...
Realization and Modeling of Metamaterials Made of rf Superconducting Quantum-Interference Devices
(American Physical Society, 2013-12-18)
We have prepared meta-atoms based on radio-frequency superconducting quantum-interference devices (rf SQUIDs) and examined their tunability with dc magnetic field, rf current, and temperature. rf SQUIDs are superconducting ...
