Cosmic Inflation provides a window into the highest energy scales realized in the history of our universe. Higgs Inflation, wherein the Standard Model Higgs or a variant is identified as the inflaton, provides a minimal framework for incorporating cosmic inflation into the Standard Model. In this talk I will revisit particle production in Higgs Inflation, and present new idiosyncratic aspects...
Experiments with liquid argon are being developed for direct detection of dark matter into the neutrino fog, for mass scales from 0.5 GeV/c$^2$ to >1000 TeV/c$^2$. This builds on the work of the DEAP-3600 detector, currently running at SNOLAB, as well as on the DarkSide-20k detector, under assembly at the LNGS underground laboratory in Italy. Recent results from the analysis of DEAP-3600 data...
The SuperCDMS-HVeV (High-Voltage with eV resolution) program is an R&D project focused on developing detectors with low energy resolution to search for low-mass dark matter (≲ 1 GeV/c2), study charge-transport in cryogenically cooled crystals, and probe unclassified backgrounds at low energy. The program utilizes gram-scale silicon detectors instrumented with TES (transition-edge sensor)-based...
The next-generation SuperCDMS experiment at the SNOLAB underground laboratory is designed to probe dark matter particles with masses below 10 GeV/c² using highly sensitive silicon and germanium cryogenic detectors. Before the experiment undergoes commissioning, it is essential to test these detectors in an environment with similar conditions to assess their performance, optimize operational...
Quantum technologies based on solid-state devices attract a growing interest in both academic and industrial research, which is why understanding their performance limitations and finding effective mitigation strategies is a key priority. Even though quantum coherence times of superconducting circuits have increased from nanoseconds to tens and hundreds of microseconds, further improvements...
