[institut] Center for Solid State Physics and New Materials Seminar - Friday, April 19th 2019 at 13:00 h

[Nenad Lazarevic]

Поштоване колегинице и колеге,

Са задовољством вас позивам на семинар Центра за физику чврстог стања и 
нове материјале под насловом:

"Superconductivity and Magnetism in 2D Materials"

који ће одржати др Чедомир Петровић, Брукхејвен национала лабораторија, 
САД.  Семинар ће се одржати у читаоници Института за физику „Др Драган 
Поповић“ у петак, 19. априла 2019. године, са почетком у 13:00 часова.

Срдачан поздрав,
Ненад Лазаревић

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].
