The field of direct dark matter detection has recently entered the so-called neutrino fog, meaning that the most sensitive experiments are now detecting significant nuclear event rates caused by coherent scattering of solar neutrinos. Because the nuclear recoil directions for dark matter and neutrinos differ, new types of detectors capable of measuring these directions would have a powerful...
Current detection methods for Weakly Interacting Massive Particle (WIMP) dark matter are approaching the so-called "neutrino fog," where irreducible background from solar neutrinos will obscure dark matter signals. To overcome this challenge, directional discrimination of events is critical. We propose developing a diamond-based particle detector that utilizes embedded quantum sensors to...
The XENONnT detector, located at Laboratori Nazionali del Gran Sasso, in Italy, utilizes 5.9 tonnes of instrumented liquid xenon in the direct search for weakly-interacting massive particle (WIMP) dark matter. Having achieved unprecedented levels of target purity, it is sensitive to a plethora of signals beyond WIMPs. This talk will present an overview of the experiment and its perfomance in...
If dark matter is ultralight, the number density of dark matter is very high and the techniques of zero-temperature field theory are no longer valid. The dark matter number density modifies the vacuum giving it a non-negligible particle occupation number. For fermionic dark matter, this occupation number can be no larger than one. However, in the case of bosons the occupation number is...
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first tonne-scale experiment using cryogenic calorimeters. The detector is located underground at the Laboratori Nazionali del Gran Sasso in Italy and consists of 988 TeO2 crystals operated in a dilution refrigerator at a base temperature of about 10 mK. Thanks to the large exposure, sharp energy resolution, segmented...
