Equilibrium and eruption of solar coronal magnetic structures
, 2014 In this thesis magnetostatic and thermal equilibria of several coronal magnetic structures are considered. A model is set up for the eruption of a prominence (modelled as a twisted flux tube) magnetically coupled to a coronal mass ejection (an ...

Simulating the in situ condensation process of solar prominences [PDF]
, 2017 Prominences in the solar corona are a hundredfold cooler and denser than their surroundings, with a total mass of 1013 up to 1015 g. Here, we report on the first comprehensive simulations of three-dimensional, thermally and gravitationally stratified ...

Development and application of a global magnetic field evolution model for the solar corona
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites
Advanced Optical Materials, EarlyView.Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

DISCRETE-ALFVEN WAVES IN SOLAR LOOP PROMINENCES
, 2015 It is shown that a discrete Alfven wave can explain the natural oscillations of solar loop prominences by considering the existence of a current flow. Discrete Alfven waves are a new class of Alfven waves which is described by the inclusion of the finite

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Advanced Optical Materials, EarlyView.This work studies the effect of halide alloying in Cs3Bi2(Br1−xIx)9 (0 ≤ x ≤ 1) semiconductors. The x = 0.6 shows the smallest bandgap, lowest exciton binding energy, and longest charge carrier lifetimes, showing promising properties for optoelectronic and photocatalytic applications.
