Membru corespondent Ion Geru este un savant cu renume \u00een domeniul fizicii st\u0103rii condensate \u015fi a proceselor de rezonan\u0163\u0103 magnetic\u0103, fondator de direc\u0163ii \u015ftiin\u0163ifice noi: \u201cDespic\u0103ri gigantice de spin \u00een semiconductori semimagnetici\u201d \u015fi \u201cSpectroscopia de micro- \u015fi radiounde a excitonilor \u00een semiconductori\u201d. Domeniile sale de cercetare \u0163in de teoria simetriei, spectroscopia de micro- \u015fi radiounde a corpului solid, studiul propriet\u0103\u0163ilor electrice \u015fi magnetice ale supraconductorilor cu temperaturi critice \u00eenalte, spectroscopia optic\u0103 a fullerenelor, cercetarea magneticilor moleculari.<\/p>\n

Printre rezultatele \u015ftiin\u0163ifice fundamentale ob\u0163inute se eviden\u0163iaz\u0103: prezicerea rezonan\u0163ei duble electron-nucleare magneto-acustice \u00een medii condensate \u015fi a rezonan\u0163ei duble radio-optice a excitonilor, confirmate ulterior experimental; identificarea existen\u0163ei numai a 4 grupuri de simetrie magnetic\u0103 \u00een patru culori pentru sisteme cu degenerare Kramers a nivelelor energetice (\u00een locul celor 58 grupuri \u00een dou\u0103 culori utilizate tradi\u0163ional); elaborarea metodei de modificare dirijat\u0103 a tipului de ordonare magnetic\u0103 \u00een clusteri dimerici; eviden\u0163ierea unui tip nou de degenerare a nivelelor \u015fi benzilor de cvasienergie, condi\u0163ionat\u0103 de necomutarea operatorului revers\u0103rii timpului cu operatorii de translare \u00een timp.<\/p>\n

Este autor a concep\u0163iei \u015ftiin\u0163ifice noi \u201creversarea par\u0163ial\u0103 a timpului\u201d, confirmat\u0103 prin date experimentale. Pe baza teoriei grupurilor a demonstrat c\u0103 datorit\u0103 existen\u0163ei simetriei \u00een raport cu reversarea timpului are loc interzicerea anumitor direc\u0163ii de orientare \u00een spa\u0163iu a momentelor magnetice ale ionilor paramagnetici din clusteri cu degenerare Kramers a nivelelor energetice. Aceast\u0103 selec\u0163ie a direc\u0163iilor posibile de orientare \u00een spa\u0163iu a momentelor magnetice poate fi considerat\u0103 ca rezultat al unei corela\u0163ii anterior necunoscute dintre propriet\u0103\u0163ile operatorului revers\u0103rii timpului \u015fi structura grupurilor de simetrie magnetic\u0103 \u00een patru culori. O alt\u0103 consecin\u0163\u0103 a simetriei inversiei temporare este stabilitatea popula\u0163iilor nivelelor de spin a sistemelor cuantice cu degenerare Kramers \u00een raport cu distorsiunile structurale.<\/p>\n
