Geometrical frustration in strongly correlated systems can give rise to a plethora of novel
ordered states and intriguing magnetic phases, such as quantum spin liquids,–. Promising …

Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly
correlated materials such as cuprates originate from Coulomb exchange interactions. The …

The emergence of quasiparticles in quantum many-body systems underlies the rich
phenomenology in many strongly interacting materials. In the context of doped Mott …

Quantum interference can deeply alter the nature of many-body phases of matter. In the
case of the Hubbard model, Nagaoka proved that introducing a single itinerant charge can …

The emergence of moiré materials with flat bands provides a platform to systematically
investigate and precisely control the correlated electronic phases. Here we report on a rich …

We investigate fermionic Mott insulators in a geometrically frustrated triangular lattice, a
paradigm model system for studying spin liquids and spontaneous time-reversal symmetry …

We introduce density imbalanced electron-hole bilayers at a commensurate 2: 1 density
ratio as a platform for realizing novel phases of electrons, excitons, and trions. Through the …

We uncover a superconducting state with partial spin polarization induced by a magnetic
field. This state, which we call “magnonic superconductor,” lacks a conventional pairing …
