Abstract of the talk

Transition metal phthalocyanine (TM-Pc) grafted to two-dimensional materials
constitute promising platforms for densely packed single-molecule magnets
(SMMs).
Here, I will provide a background in this field as well as I will share
the main
results of our recent theoretical first-principles calculations.

For example, our ab initio calculations in the framework of the density
functional
theory indicate that (Fe-PC) could be covalently adsorbed to graphene layer.
Further, using the combination of group theory, ligand field splitting,
and the
calculated eigenvalue spectrum, we resolved the electronic structure and
predict the
spin states of both isolated FePc and FePc-graphene hybrid systems. The
studies
mediate a successful synthesis of densely packed FePc molecules on
graphene and may
open up a new avenue in designing scalable 2D material–SMM hybrid systems for
spintronics applications.

Abstract of the talk

The problem of the propagation of the single hole introduced into the
antiferromagnetic ground state is one of the most studied in the
“cuprate physics”, for it can be solved in a relatively controlled
manner. Nevertheless, the possibility of simulating hole-doped
antiferromagnets in the cold atom experiments [1], have recently
triggered a renewed interest into this problem. In this talk, after a
brief introduction, I plan to give an overview of some of our most recent
studies which try to understand the propagation of the single hole in the
antiferromagnet using the magnon language, with a special attention paid
to the interaction between the magnons [2-3].

Streszczenie wykładu Abstract of the talk

Omówię wyniki teoretyczne i ich porównanie ilościowe dla nadprzewodników
wysokotemperaturowych z miedzią, w oparciu o nasze podejście wariacyjne do
modelu t-J-U (systematyczne wyjście poza teorię pola średniego). Materiał
stanowi treść obszernego artykułu przeglądowego przygotowanego dla Physics
Reports. Spróbuję przekonać słuchaczy, że podejście oparte o silne
korelacje między-elektronowe stanowi podstawę do pełnej ilościowej teorii
tego nadprzewodnictwa, pod warunkiem uwzględnienia fluktuacji kwantowych
(paramagnonów i plazmonów). Prace wykonane ze
współpracownikami: M. Fidrysiakiem, M. Zegrodnikiem oraz A. Biborskim,
finansowane z pomocą
grantu NCN OPUS (2019-21).

I will discuss theoretical results and their quantitative comparison with
experiments for cuprate high temperature superconductors. We use
variation approach to the t-J-U model (going beyond the mean field
theory). The material presented in the talk is the content of a
comprehensive review article for Physics Reports. I will try to convince
the audience that the approach build on strong inter-electron correlations
provides the basis for the full quantitative theory of this
superconductivity provided
that we take into account quantum fluctuations (paramagnons and plasmons).
Work has been done with co-workers: M. Fidrysiak, M. Zegrodnik and A.
Biborski, it was financed with help of NCN OPUS grant (2019-21).

Streszczenie wykładu Abstract of the talk

Dynamical heterogeneity is a spatiotemporal fluctuation in the local atomic
dynamical behavior and it is known to control phase transitions in
amorphous solids
as well as diffusion and viscosity near biological interfaces. Here we
show that
this concept can be used to unravel dynamical motifs governing not only
the glassy
relaxations of molecular solids but also the ionic diffusion process in
number of
crystalline solid electrolytes. We employ ab initio molecular dynamics (AIMD)
simulations together with case-tailored data-analysis tools to shed light
on: oxide
ion trapping in yttrium and niobium doped δ-Bi2O3, the collective nature
of ionic
diffusion in δ-Bi2O3, the cooperative and heterogeneous changes in
hydrogen-bond
dynamics controlling α- and β-relaxation processes in glassy polyols, and
the rapid
ionic conductivity change of perovskite Na0.5Bi0.5TiO3 associated with
change in
Na/Bi ratio.

In the ordinary picture of superconductivity, electrons with spin s = 1/2
form Cooper pairs whose spin structure is singlet (S = 0) or triplet (S =
1). However, when the electronic structure near the Fermi level is
characterized by fermions with angular momentum j = 3/2, e.g., due to
strong spin-orbit interaction, novel pairing states such as even-parity
quintet (J = 2) and odd-parity septet (J = 3) are allowed. Prime
candidates for such exotic pairing are half-Heusler compounds, which
exhibit unconventional superconducting properties [1-4]. Recently, we have
shown that superconductivity in the non-centrosymmetric bismuthide LuPdBi
can be described by a mixture of isotropic even-parity singlet and
anisotropic odd-parity septet pairing, whose ratio can be tuned by
electron irradiation [5]. By means of magnetotransport and penetration
depth measurements, we found that carrier concentrations and impurity
scattering both increase with irradiation, resulting in a nonmonotonic
change of the superconducting gap structure. Our findings shed new light
on our fundamental understanding of unconventional superconducting states
in topological materials.

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.
