Nature of order from random two-body interactions
Nature of order from random two-body interactions
We investigate the origin of order in the low-lying spectra of many-body systems with random two-body interactions. Our study based both on analytical as well as on numerical arguments shows that except for the most J-stretched states, the ground states in the higher J-sectors are more orderly and d...

520 | |a We investigate the origin of order in the low-lying spectra of many-body systems with random two-body interactions. Our study based both on analytical as well as on numerical arguments shows that except for the most J-stretched states, the ground states in the higher J-sectors are more orderly and develop larger energy gaps than the ones in the J = 0-sector. Due to different characteristic energy scales in different J-sectors the J = 0 ground states may predominate only when all the states are taken together. (C) 2001 Elsevier Science B.V.
