Nonadiabatic transition at a band-touching point
Low-energy Hamiltonians with a linear crossing in their energy dispersion (dubbed Dirac Hamiltonians) have recently been the subject of intense investigations. The linear dispersion is often the result of an approximation in the energy dispersion at the band-touching point in which higher order term...
