Fukushima plutonium effect and blow-up regimes in neutron-multiplying media

open access: yes, 2013
It is shown that the capture and fission cross-sections of 238U and 239Pu increase with temperature within 1000-3000 K range, in contrast to those of 235U, that under certain conditions may lead to the so-called blow-up modes, stimulating the anomalous ...

5d Higgs Branch Localization, Seiberg-Witten Equations and Contact Geometry

open access: yes, 2015
In this paper we apply the idea of Higgs branch localization to 5d supersymmetric theories of vector multiplet and hypermultiplets, obtained as the rigid limit of $\mathcal{N} = 1$ supergravity with all auxiliary fields.
