Szanowni Państwo,
uprzejmie zawiadamiam, że we wtorek 16 listopada 2021
o godzinie 14:00 na seminarium w formie zdalnej,
za pośrednictwem platformy Zoom,
Dr Jacek Herbrych
Katedra Fizyki Teoretycznej
Wydział Podstawowych Problemów Techniki
Politechnika Wrocławska
wygłosi referat p.t.:
Niskowymiarowe orbitalnie-selektywne izolatory Motta - właściwości
magnetyczne i elektryczne
Streszczenie referatu i instrukcję połączenia się z transmisją seminarium
znajdą państwo poniżej.
Przypominam następujące ważne informacje:
* Seminarium ma unikalny identyfikator spotkania Zoom i hasło, które
wszyscy uczestnicy otrzymają w zawiadomieniu.
* Mikrofon i kamera wideo uczestnika są domyślnie wyciszone/wyłączone. W
razie potrzeby można samemu wyłączyć wyciszenie.
* Można zadawać pytania, wirtualnie podnosząc rękę, po czym gospodarz
sesji włączy mikrofon, lub po referacie. Po zadaniu pytania proszę
pamiętać o ponownym wyciszeniu dźwięku.
* Proszę okazać prelegentowi taki sam szacunek jak zwykle osobiście,
włączając w to punktualność na seminarium.
* Zostaniecie państwo poinformowani na początku spotkania, jeśli
seminarium jest nagrywane.

Streszczenie wykładu Abstract of the talk
Motivated by increasing experimental evidence of the exotic magnetism in
low-dimensional iron-based materials, I will discuss the magnetic and
electronic
states of the multiorbital Hubbard chains and ladders. Iron-based
superconductors
display various phases originating in the competition between electronic,
orbital,
and spin degrees of freedom. Prominent among these novel effects is the
orbital-selective Mott phase (OSMP), where interactions acting on a
multiorbital
Fermi surface cause the selective localization of electrons on one (or
more) of the
orbitals. As a consequence, the system is in a mixed state with coexisting
metallic
and Mott-insulating bands. In my talk, I will show that the magnetic ordering
associated with the low-dimensional OSMP combines phenomena known from
cuprates with
those found in manganites. I will discuss the block magnetism (ordering
similar to
the stripes found in cuprates), the chiral magnetism without frustration, the
phase-separation-like phase akin to the manganites, and the novel quantum
spin flux
phase. Furthermore, since the system is in the overall metallic state, I
will also
discuss the electric properties of the OMSP.
