Measurement of the bulk radioactive contamination of detector-grade silicon with DAMIC at SNOLAB

We present measurements of bulk radiocontaminants in the high-resistivity silicon CCDs from the DAMIC experiment at SNOLAB. We utilize the exquisite spatial resolution of CCDs to discriminate between

Cosmogenic activation of silicon

The production of $^{3}\mathrm{H}$, $^{7}\mathrm{Be}$, and $^{22}\mathrm{Na}$ by interactions of cosmic-ray particles with silicon can produce radioactive backgrounds in detectors used to search for

Impact of ionizing radiation on superconducting qubit coherence

TLDR
Evidence is provided that ionizing radiation from environmental radioactive materials and cosmic rays contributes to an elevated quasiparticle density, which it is predicted would ultimately limit the coherence times of superconducting qubits of the type measured here to milliseconds.

Flat-band superconductivity for tight-binding electrons on a square-octagon lattice

The discovery of superconductivity in twisted bilayer graphene has triggered a resurgence of interest in flat-band superconductivity. Here, we investigate the square-octagon lattice, which also
