Уважаемые коллеги!
На заседании Ученого совета ИТФ в пятницу 12.09 будут заслушаны 2 доклада:

URhGe - Altermagnetic Ferromagnet
It is well known that the anomalous Hall effect in ferromagnetic and strongly paramagnetic metals in addition to electron skew scattering on impurities is determined by internal mechanism linked to the Berry curvature, a quantum-mechanical property of the electron states of a perfect crystal. Experimentally, however, it has been established that the Berry curvature does not play any role in the Hall resistance of the ferromagnet URhGe. URhGe is so called altermagnetic ferromagnet which crystal symmetry includes operation of time inversion only in combination with rotations and reflections. The explanation for strictly zero Berry curvature of electronic states in this material lies in the non-symmorphic symmetry of its crystal lattice.

Phase Diagram of UTe${}_2$
The pressure-temperature phase diagram of superconducting UTe${}_2$ with three lines of the second- order phase transitions cannot be explained in terms of successive transitions to superconducting states with a decrease in symmetry. The problem is solved using a two-band description of the superconducting state of UTe${}_2$.

При числе желающих не менее 5 будет организован автобус.
Для записи на автобус из Москвы в Черноголовку необходимо до 17:00 четверга отправить письмо на адрес электронной почты bus@itp.ac.ru
После этого записавшимся до 20:00 поступит подтверждение об отправке или неотправке автобуса в зависимости от числа записавшихся.
Запись на обратный автобус - на Ученом совете.
