Mode-locking instability and multiple soliton formation in GaN polariton waveguide cavities
O. Bahrova, V. Develay, H. Souissi +10
We study the emergence of multi-soliton regimes in 1D ridge polariton waveguides of two different lengths. We show that by varying the position of the gain, which in out-of-equilib…

Dirac points annihilation and its obstruction characterized by Euler number and quaternionic charges in kagome lattice
M. Finck, D. Solnyshkov, J. Dubois +1
We investigate the topological phenomenon of Dirac point annihilation and its obstruction in three-band, real symmetric Hamiltonians with time-reversal symmetry, and their relation…
