Determination of a Wave Function Functional [PDF]

open access: yesPhysical Review Letters, 2004
In this paper we propose the idea of expanding the space of variations in standard variational calculations for the energy by considering the wave function $ψ$ to be a functional of a set of functions $χ: ψ= ψ[χ]$, rather than a function. In this manner a greater flexibility to the structure of the wave function is achieved.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...
