Dark Matter May Lurk at Low-Energy Frontiers

In an article submitted to Physical Review D, CPC members Noah Kurinsky and Gordan Krnjaic collaborate with Dan Baxter (KICP) and Yoni Kahn (UIUC) to present a novel interpretation of excess events observed at various low-threshold dark matter searches. They found that the anomalous results across various detectors operating in dramatically different experimental conditions could be reconciled if these events arise from dark matter interactions inside these detectors that excite collective charge oscillations (“plasmons”), known to exist in semiconductor devices. This research was profiled in Scientific American.
