In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Ferromagnetic properties of hexaferrites induce magnetisation inside their crystal structure,
separating them into uniaxial and ferroxplana hexaferrites. Y-type is the first observed …

Collective excitations of bound electron-hole pairs—known as excitons—are ubiquitous in
condensed matter, emerging in systems as diverse as band semiconductors, molecular …

The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice
site. When it is doped with additional carriers, they are unstable to spin-fluctuation-mediated …

As the oldest known magnetic material, magnetite (Fe3O4) has fascinated mankind for
millennia. As the first oxide in which a relationship between electrical conductivity and …

We present a calculation of the recombination rate of the excited holon-doublon pairs based
on the<? format?> two-dimensional model relevant for undoped cuprates, which shows that …

The non-equilibrium approach to correlated electron systems is often based on the
paradigm that different degrees of freedom interact on different timescales. In this context …

We study the relaxation mechanism of a highly excited charge carrier propagating in the
antiferromagnetic background modeled by the tJ Hamiltonian on a square lattice. We show …

We use ultrafast optical spectroscopy to observe binding of charged single-particle
excitations (SE) in the magnetically frustrated Mott insulator Na 2 IrO 3. Above the …

Recent optical conductivity measurements reveal the presence of Hubbard excitons in
certain Mott insulators. In light of these results, it is important to revisit the dynamics of these …
