Towards Quantum-Dot Detectors as Barcodes for Dark Matter Interactions
Marek Matas, Andrea Gallo Rosso, Antonio Cammarata +6
Quantum dots are tunable semiconductor nanocrystals that can be produced at industrial scales. We present the first ab initio calculation of the scattering of dark matter on electr…
The Dark Photon: a 2026 Perspective
Andrea Caputo, Rouven Essig
We give a pedagogical overview of dark photons. We describe the theory and their importance in particle physics research, and discuss searches using laboratory, astrophysical, and…
Semi-Analytic Modeling of Dark Matter Subhalo Encounters with Thin Stellar Streams: Statistical Predictions for GD-1-like Streams in CDM
Duncan K. Adams, Aditya Parikh, Oren Slone +3
Stellar streams from disrupted globular clusters are dynamically cold structures that are sensitive to perturbations from dark matter subhalos, allowing them in principle to trace…
The Migdal effect in Semiconductors for the Effective Field Theory of Dark Matter Direct Detection
Kim V. Berghaus, Rouven Essig, Megan H. McDuffie
The Migdal effect in semiconductors, prompt ionization from a primary nuclear scattering event, can be described across all kinematic regimes using an effective field theory that e…
Astrophysical uncertainties challenge 21-cm forecasts: A primordial black hole case study
Dominic Agius, Rouven Essig, Daniele Gaggero +3
The 21-cm signal is a powerful probe of the early Universe's thermal history and could provide a unique avenue for constraining exotic physics. Previous studies have forecasted str…
Pushing the Limits of Atomic Dark Matter: First-Principles Recombination Rates and Cosmological Constraints
Jared Barron, Rouven Essig, Megan H. McDuffie +2
Minimal atomic dark matter with its distinctive cooling mechanisms offers an instructive framework for understanding the potential impact of dark matter on small-scale structure fo…
