DOI: 10.1093/mnras/staa581
Abstract: Magnetic fields are believed to be generated in the cores of massive main sequence stars, and these may survive on to later stages of evolution. Observations of depressed dipole modes in red giant stars have… read more here.

DOI: 10.1103/physrevb.99.121111
Abstract: We study the semi-classical theory of wave packet dynamics in crystalline solids extended to include the effects of a non-uniform electric field. In particular, we derive a correction to the semi-classical equations of motion (EOMs)… read more here.

DOI: 10.1103/physrevlett.128.083001
Abstract: Photoelectron interferometry with femtosecond and attosecond light pulses is a powerful probe of the fast electron wave-packet dynamics, albeit it has practical limitations on the energy resolution. We show that one can simultaneously obtain both… read more here.
