Soft x-rays induce femtosecond solid-to-solid phase transition
Franz Tavella, Hauke Höppner, Victor Tkachenko +12
Soft x-rays were applied to induce graphitization of diamond through a non-thermal solid-to-solid phase transition. This process was observed within poly-crystalline diamond with a…
Nuclear excitation by two-photon electron transition
A. V. Volotka, A. Surzhykov, S. Trotsenko +3
A new mechanism of nuclear excitation via two-photon electron transitions (NETP) is proposed and studied theoretically. As a generic example, detailed calculations are performed fo…
An Addendum to the Heisenberg-Euler effective action beyond one loop
Holger Gies, Felix Karbstein
We study the effective interactions of external electromagnetic fields induced by fluctuations of virtual particles in the vacuum of quantum electrodynamics. Our main focus is on t…
Nonabelian Higgs models: paving the way for asymptotic freedom
Holger Gies, Luca Zambelli
Asymptotically free renormalization group trajectories can be constructed in nonabelian Higgs models with the aid of generalized boundary conditions imposed on the renormalized act…
Multiconfiguration calculations of electronic isotope shift factors in Al I
Livio Filippin, Randolf Beerwerth, Jörgen Ekman +3
The present work reports results from systematic multiconfiguration Dirac-Hartree-Fock calculations of electronic isotope shift factors for a set of transitions between low-lying s…
Entropy spectrum of charged BTZ black holes in massive gravity's rainbow
B. Eslam Panah, S. Panahiyan, S. H. Hendi
Regarding the significant interests in massive gravity and combining it with gravity's rainbow and also BTZ black holes, we apply the formalism introduced by Jiang and Han in order…
