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 to the insulating side of the gap opening. Here we report the high-magnetic field phase diagram of graphite to exhibit just such a crossover. By way of comprehensive angle-resolved magnetoresistance measurements, we demonstrate that the underlying band gap opening occurs inside the magnetic field-induced phase, paving the way for a systematic study of the BCS-BEC-like crossover by means of conventional condensed matter probes.","lang":"eng"}],"publication_status":"published","publication":"Scientific Reports","_id":"7066","author":[{"last_name":"Zhu","full_name":"Zhu, Z.","first_name":"Z."},{"first_name":"R.
