DESCRIPTION:Title: Axion DM detection using shift currentabstract: In this
  talk\, I will show the possibility of searching for axions using the shif
 t current. The shift current is a photon-induced current which arises in m
 aterials with broken spatial inversion symmetry. It can be utilized to det
 ect axion-induced photons. My talk will consist of an introduction of the 
 shift current\, a strategy for axion detection using shift current\, and t
 he expected sensitivity. This talk is based on our recent work arXiv:2505.

DESCRIPTION:Title: Leptogenesis from magnetic helicity of gauged U(1)_{B
 −L}Abstract: If the B−L symmetry is gauged with the addition of rig
 ht-handed neutrinos\, the standard model B−L current is anomalous with
  respect to the B−L gauge field itself. Then\, the anomaly relation im
 plies that the magnetic helicity of the B−L gauge field is related to 
 the standard model B−L charges\, although the whole universe is B−L
  neutral with right-handed neutrinos. Based on this\, we propose a new le
 ptogenesis scenario with the gauged B−L symmetry as follows. First\, t
 he magnetic helicity of the B−L gauge field is generated\, e.g.\, by t
 he axion inflation\, together with the standard model and right-handed neu
 trino B−L charges\, with the net B−L charge kept zero. The B−L
  charges in the standard model and right-handed neutrino sectors are then
  subject to washout effects from the interactions between them. After the 
 washout effects decouple\, the B−L gauge symmetry is Higgsed and the m
 agnetic helicity of the B−L gauge field decays and generates B−L c
 harges in the both sector\; thanks to the washout effects\, we obtain a no
 n-zero B−L asymmetry. We show that the baryon asymmetry of the univers
 e can be generated in this scenario\, discussing the decay of the magnetic
  helicity of the B−L gauge field and the interactions between the righ
 t-handed neutrinos and the standard model particles.
