Zero-range effective field theory for resonant wino dark matter. Part III. Annihilation effects
Journal of High Energy Physics, 2018 Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective field theory (ZREFT) in which the winos interact nonperturbatively ...

Advanced Materials Interfaces, EarlyView.Unexpected results show that the singlet‐oxygen based antifungal activity of porphyrin‐based Metal‐Organic Frameworks is far below expectations while the standalone ligand is more efficient. We attribute these behaviours to inefficient exciton migration and gas diffusion leading to low singlet oxgyen concentrations at and beyond the MOF‐gas interface ...

Sommerfeld enhancement of resonant dark matter annihilation
Physics Letters B, 2023 The dark matter annihilation cross section can be amplified by orders of magnitude if the annihilation occurs into a narrow resonance, or if the dark-matter particles experience a long-range force before annihilation (Sommerfeld effect).

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...

Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging
Advanced Optical Materials, EarlyView.By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

The Gaze as constituent and annihilator [PDF]
Journal of Aesthetics & Culture, 2012 This article aims to join the contemporary effort to promote a psychoanalytic renaissance within cinema studies, post Post-Theory. In trying to shake off the burden of the 1970s film theory’s distortion of the Lacanian Gaze, rejuvenating it with the strength of the Real and fusing it with Freudian thoughts on the uncanny, hopefully this new dawn can be
