Motivated by the recently discovered high-T c nickelate superconductor La 3 Ni 2 O 7, we
investigate the S±-wave superconductivity (SC) in a two-dimensional Hubbard model on a …

Motivated by the recently discovered high $ T_c $ nickelate superconductor $\mathrm
{La_3Ni_2O_7} $, we investigate superconductivity in a two dimensional Hubbard model on …

Numerical approaches to the correlated electron problem have achieved considerable
success, yet are still constrained by several bottlenecks, including high order polynomial or …

Heavy-fermion superconductors exhibit unusual properties such as low transition
temperatures, large specific heat jumps, and normal states with universal two-fluid …

In quantum materials, electrons that have strong correlations tend to localize, leading to
quantum spins as the building blocks for low-energy physics. When strongly correlated …

Layered organic superconductors of the BEDT family are model systems for understanding
the interplay of the Mott transition with superconductivity, magnetic order, and frustration …

Kondo systems ranging from the single Kondo impurity to heavy fermion materials present
us with a plethora of unconventional properties whose theoretical understanding is still one …

We propose mechanism for pressure-induced transitions between ferromagnetic and
antiferromagnetic phases that relies on a competition between characteristic energy scales …

Superconductivity in heavy-fermion systems has an unconventional nature and is
considered to originate from the universal features of the electronic structure. Here, the …

We discuss a mechanism of real-space spin-triplet pairing, which is an alternative to the one
due to quantum paramagnon excitations, and demonstrate its applicability to UGe 2. Both …
