Presymplectic BV-AKSZ for $N=1$, $D=4$ Supergravity
We elaborate on the presymplectic BV-AKSZ approach to supersymmetric systems. In particular, we construct such a formulation for the $N=1$, $D=4$ supergravity by taking as a target space the Chevalley-Eilenberg complex of the super-Poincaré algebra which, as we demonstrate, admits an invariant presymplectic structure of degree $3$. This data encodes a full-scale Batalin-Vilkovisky formulation of the system, including a concise form of the BV master action. The important feature of (presymplect…

Unraveled origin of the multi-directional and super wide optical-response found on metal/n-Si
The optical responses for UV to NIR and muti-directional photo current have been found on Au (metal) on n-Si device. The unique phenomena have been unresolved since the first sample fabricated in 2007. The self organized sub-micron metal with various crystal faces was supposed to activate as an optical wave guide into Si surface. This, however, is insufficient to explain the unique features above. Thus, for more deep analysis, returning to consider the Si-band structure, indirect/direct transit…
