Entanglement and correlation in two-nucleon systems
A T Kruppa, J Kovács, P Salamon +1
We examine the mode entanglement and correlation of two fermionic particles. We study the one- and two-mode entropy and a global characteristic, the one-body entanglement entropy.…
Description of two-electron atoms with correct cusp conditions
A. T. Kruppa, J. Kovács, I. Hornyak
New sets of functions with arbitrary large finite cardinality are constructed for two-electron atoms. Functions from these sets exactly satisfy the Kato's cusp conditions. The new…
12C/13C isotopic ratios in red-giant stars of the open cluster NGC 6791
László Szigeti, Szabolcs Mészáros, Verne V. Smith +10
Carbon isotope ratios, along with carbon and nitrogen abundances, are derived in a sample of 11 red-giant members of one of the most metal-rich clusters in the Milky Way, NGC 6791.…
Diphoton excess and VV-scattering
G. Cynolter, J . Kovács, E. Lendvai
We consider minimal effective interactions of the 750 GeV mass resonance observed recently by ATLAS and CMS. Assuming a new scalar and gauge invariant effective interactions leads…
Investigating magnetic activity in very stable stellar magnetic fields: long-term photometric and spectroscopic study of the fully convective M4 dwarf V374 Peg
K. Vida, L. Kriskovics, K. Oláh +8
The ultrafast-rotating () fully convective single M4 dwarf V374 Peg is a well-known laboratory for studying intense stellar activity in a stable magnet…
