Paleomagnetic signatures of core-mantle interactions inferred from top-heavy thermochemical geodynamo simulations
Souvik Naskar, Jonathan E. Mound, Christopher J. Davies +3
The time-averaged geomagnetic field provides crucial insights into deep Earth dynamics and thermal core-mantle interactions. Paleomagnetic observations and numerical dynamo simulat…

Geomagnetic signatures of the slurry F-layer inferred from dynamo simulations
Ludovic Huguet, Thomas Frasson, Souvik Naskar +5
Seismic observations indicate that the lowermost portion of Earth's liquid core is density stratified. The existence of this so-called F-layer challenges classical theories of core…

Accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos
Andrew T. Clarke, Christopher J. Davies, Souvik Naskar +1
Polarity reversals are a key feature of Earth's magnetic field, yet the processes governing them are still poorly understood. Dipole reversals have been found in many numerical dyn…
