Ground state phase diagram of the repulsive fermionic Hubbard model on the square lattice from weak-coupling
Fedor Simkovic, Xuan-Wen Liu, Youjin Deng +1
We obtain a complete and exact in the weak-coupling limit () ground state phase diagram of the repulsive fermionic Hubbard model on the square lattice for filling…
Partial restoration of isospin symmetry for neutrinoless double beta decay in the deformed nuclear system of Nd
Dong-Liang Fang, Amand Faessler, Fedor Simkovic
In this work, we calculate the matrix elements of -decay of Nd with the deformed pn-QRPA method. We adopted the approach introduced by Rodin, Faessler [Phys. Rev. C84…
A search for double-electron capture in 74Se using coincidence/anticoincidence gamma-ray spectrometry
M. Jeskovsky, D. Frekers, A. Kovacik +6
Evaluation of single, coincidence and anticoincidence gamma-ray spectrometry methods has been carried out with the aim to search for double-electron capture in 74Se. This process i…
The light neutrino exchange mechanism of the -decay with left- and right-handed leptonic and hadronic currents revisited
Dusan Stefanik, Rastislav Dvornicky, Fedor Simkovic +1
The extension of Majorana neutrino mass mechanism of the neutrinoless double-beta decay () with the inclusion of right-handed leptonic and hadronic currents is revisited. Whi…
Structure of the two-neutrino double- decay matrix elements within perturbation theory
Dusan Stefanik, Fedor Simkovic, Amand Faessler
The two-neutrino double- Gamow-Teller and Fermi transitions are studied within an exactly solvable model, which allows a violation of both spin-isospin SU(4) and isospin SU(2) s…
Degeneracies of particle and nuclear physics uncertainties in neutrinoless double beta decay
E. Lisi, A. Rotunno, F. Simkovic
Theoretical estimates for the half life of neutrinoless double beta decay in candidate nuclei are affected by both particle and nuclear physics uncertainties, which may complicate…
