Magnetic field tuning of an excitonic insulator between the weak and strong coupling regimes in quantum limit graphite
The excitonic insulator phase has long been predicted to form in proximity to a band gap opening in the underlying band structure. The character of the pairing is conjectured to crossover from weak (BCS-like) to strong coupling (BEC-like) as the underlying band structure is tuned from the metallic t...
