Long-range exciton transport and slow annihilation in two-dimensional hybrid perovskites
Nature Communications, 2020 Two-dimensional hybrid organic-inorganic perovskites with strongly bound excitons and tunable structures are desirable for optoelectronic applications. Exciton transport and annihilation are two key processes in determining device efficiencies; however ...

Simplified models of dark matter with a long-lived co-annihilation partner [PDF]
Journal of High Energy Physics, 2017 We introduce a new set of simplified models to address the effects of 3-point interactions between the dark matter particle, its dark co-annihilation partner, and the Standard Model degree of freedom, which we take to be the tau lepton. The contributions

Search for Dark Matter Annihilation Signals in the H.E.S.S. Inner Galaxy Survey. [PDF]
Physical Review Letters, 2022 The central region of the Milky Way is one of the foremost locations to look for dark matter (DM) signatures. We report the first results on a search for DM particle annihilation signals using new observations from an unprecedented γ-ray survey of the ...

Celestial-body focused dark matter annihilation throughout the Galaxy [PDF]
Physical Review D, 2021 Indirect detection experiments typically measure the flux of annihilating dark matter (DM) particles propagating freely through galactic halos. We consider a new scenario where celestial bodies “focus” DM annihilation events, increasing the efficiency of

Testing CPT symmetry in ortho-positronium decays with positronium annihilation tomography [PDF]
Nature Communications, 2021 Charged lepton system symmetry under combined charge, parity, and time-reversal transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic limits, discrepancies in predictions for the electron–positron bound state (positronium
