Monodromy defects are constructed in massive Type IIA settings
This research indicates that solutions in massive Type IIA supergravity can be used to study co-dimension 2 monodromy defects in six-dimensional and five-dimensional conformal field theories, and that their defect entanglement entropy may be related to the defect's free energy and conformal weight.

Kerr-de Sitter black holes show stronger repetitive Penrose energy performance
This research indicates that Kerr-de Sitter black holes can yield higher energy return on investment and single-extraction energy capability than Kerr black holes, with the outcome depending on the cosmological parameter and decay radius.

Uncertain neutron-capture data affect r-process abundance estimates
This research indicates that uncertainties in s-process isotopic abundances, driven by neutron-capture cross-section data, make some r-process residuals significantly uncertain and identify isotopes that should be prioritized for new measurements.
