У оквиру семинара Центра за физику чврстог стања и нове материјале, у читаоници Института за физику „Др Драган Поповић“ у петак, 19. априла 2019. године, у 13:00 часова др Чедомир Петровић, Брукхејвен национала лабораторија, САД, одржаће предавање под насловом:
„Superconductivity and Magnetism in 2D Materials“
Сажетак:
Superconductivity and charge-density-wave (CDW) are traditionally
viewed as Fermi surface instabilities due to electron-phonon
coupling whereas arguments have been made both for their
cooperation and competition [1-4]. In this talk I will discuss
emergence of superconductivity in the absence of magnetism from the
standpoint of disorder in doped two-dimensional (2D) CDW conductors
ZrTe3 and 2H-TaSe2-xSx [5- 10]. In the second part of my
talk I will briefly discuss magnetic critical phenomena and effects
of size reduction in CrI3 and other 2D materials of current interest
[11-12].
