Heavy elements are intergalactic travelers

Computing Heavy Elements

Reliable calculations of the structure of heavy elements are crucial to address fundamental science questions such as the origin of the elements in the universe. Applications relevant for energy production, medicine, or national security also rely on theoretical predictions of basic properties of atomic nuclei. Heavy elements are best described within the nuclear density functional theory (DFT)...

Which elements of a finite group are non-vanishing?

‎Let $G$ be a finite group‎. ‎An element $gin G$ is called non-vanishing‎, ‎if for‎ ‎every irreducible complex character $chi$ of $G$‎, ‎$chi(g)neq 0$‎. ‎The bi-Cayley graph ${rm BCay}(G,T)$ of $G$ with respect to a subset $Tsubseteq G$‎, ‎is an undirected graph with‎ ‎vertex set $Gtimes{1,2}$ and edge set ${{(x,1),(tx,2)}mid xin G‎, ‎ tin T}$‎. ‎Let ${rm nv}(G)$ be the set‎ ‎of all non-vanishi...

Laser Spectroscopy of Heavy Elements at SHIPTRAP

The aim of this project is the investigation of atomic and nuclear properties of heavy elements with charge numbers Z 100 by laser spectroscopy. Any atomic spectroscopy, even with the most sensitive laser methods, is seriously hampered by the fact that no information on the atomic structure is available for these elements. To get acquainted with such a spectroscopy experiments were performed fo...

Lattice Results for Heavy Light Matrix Elements

Lattice results for heavy light matrix elements are reviewed and some of their implications are very briefly discussed [1]. Despite the fact that in most cases the lattice results for weak matrix elements at the moment have only a modest accuracy of about 20–30% they already have important phenomenological repercussions; e.g. for Vtd/Vts, xs/xd and B → K ∗γ. I. As samples of “new” projects, I b...
