Electromagnetic Duality and the Electric Memory Effect
Yuta Hamada, Min-Seok Seo, Gary Shiu
We study large gauge transformations for soft photons in quantum electrodynamics which, together with the helicity operator, form an ISO(2) algebra. We show that the two non-compac…
SIMP dark matter and its cosmic abundances
Soo-Min Choi, Hyun Min Lee, Min-Seok Seo
We give a review on the thermal average of the annihilation cross-sections for and general higher-order processes. Thermal average of higher order annihilations hi…
Consistency relations in multi-field inflation
Jinn-Ouk Gong, Min-Seok Seo
We study the consequences of spatial coordinate transformation in multi-field inflation. Among the spontaneously broken de Sitter isometries, only dilatation in the comoving gauge…
Large gauge transformation and little group for soft photons
Yuta Hamada, Min-Seok Seo, Gary Shiu
Recently, large gauge transformation (LGT), the residual gauge symmetry after gauge fixing that survives at null infinity, has drawn much attention concerning soft theorems and the…
Cosmic abundances of SIMP dark matter
Soo-Min Choi, Hyun Min Lee, Min-Seok Seo
Thermal production of light dark matter with sub-GeV scale mass can be attributed to self-annihilation processes. We consider the thermal average for annihilation…
Memory in de Sitter space and BMS-like supertranslations
Yuta Hamada, Min-Seok Seo, Gary Shiu
It is well known that the memory effect in flat spacetime is parametrized by the BMS supertranslation. We investigate the relation between the memory effect and diffeomorphism in d…
