The Jacobi curve of an extremal of optimal control problem is a curve in a Lagrangian Grassmannian defined up to a symplectic transformation and containing all information about the solutions of the Jacobi equations along ...

We present an ab initio study of the static Jahn-Teller (JT) effect in the magnesium phthalocyanine anion (MgPc-). The neutral MgPc has D-4h symmetry with a doubly degenerate e(g) affinity level and 14 B-1g plus 14 B-2g ...

We analyze the modular properties of the effective CFT description for Jain plateaux corresponding to the fillings nu=m/(2pm+1). We construct its characters for the twisted and the untwisted sector and the diagonal partition ...

We propose an experiment that would demonstrate the dc and ac Josephson effects in two weakly linked Bose-Einstein condensates. We consider a time-dependent barrier, moving adiabatically across the trapping potential. The ...

We discuss a minimal extension to the standard model in which there are two Higgs bosons and, in addition to the usual fermion content, two fermion doublets and one fermion singlet. The little hierachy problem is solved ...

While excitotoxicity is a major contributor to the pathophysiology of acute spinal injury, its time course and the extent of cell damage in relation to locomotor network activity remain unclear. We used two in vitro models, ...
