Balancing theory uncertainties in ab initio nuclear structure calculations: Many-body truncation versus finite basis size
L. Zurek, U. Vernik, P. Demol +3
First-principles calculations of atomic nuclei are necessarily incomplete as the Schrödinger equation is solved using approximate methods and due to the finite dimension of the emp…
High-precision ab initio calculations of nuclear binding energies: Tin isotopes from dripline to dripline
Urban Vernik, Pepijn Demol, Thomas Duguet +1
The location of the neutron drip line in tin isotopes has important consequences for our fundamental understanding of nuclear structure and nuclear forces as well as for astrophysi…
Ab initio calculations of nuclear charge radii across and beyond Sn: Putting chiral EFT nuclear interactions to the test
Pepijn Demol, Urban Vernik, Thomas Duguet +1
Charge radii are investigated along the Tin isotopic chain via ab initio Bogoliubov coupled cluster calculations at the singles and doubles level. In addition to the reproduction o…
Exploring quark mass dependent three-nucleon forces in medium-mass nuclei
Urban Vernik, Kai Hebeler, Achim Schwenk
Recently, new quark mass dependent three-nucleon (3N) forces have been identified, whose contributions in nuclear matter exceed expectations of Weinberg power-counting arguments. I…
Resonant phonon-magnon interactions in free-standing metal-ferromagnet multilayer structures
Urban Vernik, Alexey M. Lomonosov, Vladimir S. Vlasov +5
We analyze resonant magneto-elastic interactions between standing perpendicular spin wave modes (exchange magnons) and longitudinal acoustic phonon modes in free-standing hybrid me…
