NONSPONTANEOUS NEMATIC INDUCTION AND OTHER FIELD EFFECTS IN MODEL MESOGENS.

We investigate the effect of an external field on transitions and structural organization in systems of Gay-Berne (GB) particles devoid of a nematic phase in zero field. We consider GB particles both without and with a transverse dipole and observe the induction of nonspontaneous nematic and other modifications of the orientational and positional order.
