The heavy fermion (HF) state of d-electron systems is of great current interest since it
exhibits various exotic phases and phenomena that are reminiscent of the Kondo effect in f …

CaPd 2 Ge 2 which crystallizes in ThCr 2 Si 2-type body-centered tetragonal structure
exhibits superconductivity below the critical temperature T c= 1.69 K. We have investigated …

Recently, the emergence of van Hove singularity, flat band, and Dirac cone in kagome
materials has attracted tremendous interest as they are closely related to the …

Topological superconductors support Majorana modes, which are quasiparticles that are
their own antiparticles and obey non-Abelian statistics in which successive exchanges of …

The correlated multiorbital multiband electronic structures of iron-based superconductors
harbor an abundance of exotic electronic states, such as spin density waves …

We report heavy electron behavior in unconventional superconductor YFe $ _2 $ Ge $ _2
$($ T_C\,{=}\, 1.2$ K). We directly observe very heavy bands ($ m_\mathrm {eff}\sim 25 m_e …

We report results of a detailed theoretical study of the effect of Coulomb correlations on the
structural, electronic, and magnetic properties of the non-pnictide iron-based …

We performed density functional theory (DFT) calculations for UTe2 using the full electron,
linearised augmented plane-wave package Wien2K. 1 Electronic structures were converged …

ВЛИЯНИЕ КОРРЕЛЯЦИОННЫХ ЭФФЕКТОВ НА РЕШЕТОЧНЫЕ, СПЕКТРАЛЬНЫЕ И
МАГНИТНЫЕ СВОЙСТВА СВЕРХПРОВОДНИКА НА ОСНОВЕ ЖЕЛЕЗА YFe2Ge2 Page 134 …

Whereas fine-tuning to a quantum critical point leads to long-lived excitations in tightly
defined regions of parameter space, narrow bands may more generally be caused by built …
