DOI: 10.1103/physrevb.104.035128
Abstract: We show by advanced electronic structure calculations that ${\mathrm{NbO}}_{2}$ essentially is a Peierls-type material. After simulating the rutile as well as the body-centered tetragonal phase with the Bethe-Salpeter equation, we are able to reproduce the… read more here.

DOI: 10.1103/physrevb.98.100403
Abstract: The magnetic insulator $\ensuremath{\alpha}\ensuremath{-}{\mathrm{RuCl}}_{3}$ is a promising candidate to realize Kitaev interactions on a quasi-two-dimensional honeycomb lattice. We perform extensive susceptibility measurements on single crystals of $\ensuremath{\alpha}\ensuremath{-}{\mathrm{RuCl}}_{3}$, including angle dependence of the in-plane longitudinal and… read more here.

DOI: 10.1103/physrevc.103.055805
Abstract: At temperatures below 0.1 GK, the $^{19}\mathrm{F}(p,\ensuremath{\gamma})^{20}\mathrm{Ne}$ reaction is the only breakout path out of the CNO cycle. Experimental studies of this reaction are challenging from a technical perspective due to copious $\ensuremath{\gamma}$-ray background from… read more here.
