Superconductivity in infinite-layer nickelates
The recent discovery of the superconductivity in the doped infinite layer nickelates RNiO 2
(R= La, Pr, Nd) is of great interest since the nickelates are isostructural to doped (Ca, Sr) …

Quantum critical points and the sign problem
The “sign problem”(SP) is a fundamental limitation to simulations of strongly correlated
matter. It is often argued that the SP is not intrinsic to the physics of particular Hamiltonians …

Nickelate superconductors—a renaissance of the one-band Hubbard model
The recently discovered nickelate superconductors appear, at first glance, to be even more
complicated multi-orbital systems than cuprates. To identify the simplest model describing …
