Spinovaya Zhidkost' I Kvantovye Effekty V Antiferromagnetikakh

V monografii kvantovym metodom Monte-Karlo issleduetsya vliyanie kvantovykh effektov v nizkomernykh spinovykh sistemakh s S=1/2 , vzaimodeystvuyushchikh s opticheskimi i akusticheskimi modami kolebaniy, na magnitnye sostoyaniya, spektr spinovykh i fononnykh vozbuzhdeniy. Rassmatrivayutsya fazovye perekhody mezhdu singletnymi sostoyaniyami so shchel'yu v spektre spinovykh vozbuzhdeniy. Vychislyayutsya magnitnye kharakteristiki anizotropnogo frustrirovannogo dvumernogo antiferromagnetika, opredelyaetsya oblast' parametrov sushchestvovaniya kvantovoy spinovoy zhidkosti. Naydeny kvantovye ostsillyatsii magnitostriktsii v dvumernom antiferromagnetike so spin-fononnym vzaimodeystviem v magnitnom pole. V ramkakh etikh modeley ob"yasnyayutsya magnitnye svoystva singletnykh magnetikov CuGeO3, Sr2CuO3. Dannaya monografiya budet polezna magistrantam, aspirantam, nauchnym rabotnikam i professorsko-prepodavatel'skomu sostavu.
