Counting topological interface modes using simplicial characteristic classes
N. Bohlsen, I. Y. Dodin, H. Qin
A computational approach for predicting the number of topological interface modes (TIMs) in hermitian systems using the spectral flow - monopole (SFM) correspondence is presented.…

On Minimizing Phase Space Energies
Michael Updike, Nicholas Bohlsen, Hong Qin +1
A primary technical challenge for harnessing fusion energy is to control and extract energy from a non-thermal distribution of charged particles. The fact that phase space evolves…

Gromov ground state in phase space engineering for fusion energy
Hong Qin, Elijah J. Kolmes, Michael Updike +2
Phase space engineering by RF waves plays important roles in both thermal D-T fusion and non-thermal advanced fuel fusion. But not all phase space manipulation is allowed, certain…
