Shift current and ballistic have been proposed to explain the bulk photovoltaic effect (BPVE), there experiments designed separate two mechanisms. These are based on assumption that under magnetic field, can a Hall while shift cannot, which is from some energy-scale arguments has never proven. A recent work [D. Hornung R. von Baltz, Phys. Rev. B 103, 195203 (2021)] using quantum transport forma...

Some properties of the non-commutative versions of the sine-Gordon model (NCSG) and the corresponding massive Thirring theories (NCMT) are studied. Our method relies on the NC extension of integrable models and the master Lagrangian approach to deal with dual theories. The master Lagrangians turn out to be the NC versions of the so-called affine Toda model coupled to matter fields (NCATM) assoc...

We study the effect of a parallel electric field on the adiabatic motion of electrons trapped in the Io flux tube and we derive the frequency drift rate of the S-bursts emitted at the gyrofrequency. The magnetic field model is a dipole and the cyclotron maser instability is the mechanism responsible for the emission. It appears that weak values of the electric field (a few μVm−1) may change dra...
