Holographic ferromagnetism model with the Maxwell field strength corrections / Zhang, Cheng-Yuan ; Wu, Ya-Bo ; Qi, Ting
In the probe limit, we investigate the effect of the quartic field strength correction to the usual Maxwell field on the holographic paramagnetism/ferromagnetism phase transition in the background of a 4-dimensional Schwarzschild-AdS black hole spacetime. [...]

The pion-nucleon σ term from pionic atoms / Friedman, E. ; Gal, A.
Earlier work suggested that the in-medium πN threshold isovector amplitude b1(ρ) gets renormalized in pionic atoms by ∼30% away from its ρ=0 free-space value, relating such renormalization to the leading low-density decrease of the in-medium quark condensate and the pion decay constant fπ in terms of the pion-nucleon σ term σπN .

Proton decay of 108 I and its significance for the termination of the astrophysical rp -process / Auranen, K. ; Seweryniak, D. ; Albers, M. ; Ayangeakaa, A.D. ; et al
Employing the Argonne Fragment Mass Analyzer and the implantation-decay-decay correlation technique, a weak 0.50(21)% proton decay branch was identified in 108 I for the first time. [...]
