This review provides a perspective on recent developments and their implications for our
understanding of novel quantum phenomena in the physics of two-dimensional organic …

In 1991 the layered organic compound κ-(BEDT-TTF) 2 Cu 2 (CN) 3 with a triangular lattice
was synthesized for the first time. Although, originally, the focus was on the superconducting …

Quantum fluctuations can inhibit long-range ordering in frustrated magnets and potentially
lead to quantum spin liquid (QSL) phases. A prime example are gapless QSLs with …

The interplay between spin frustration and charge fluctuation gives rise to an exotic quantum
state in the intermediate-interaction regime of the half-filled triangular-lattice Hubbard model …

We have grown single crystals of PrMgAl 11 O 19, an ideal triangular-lattice antiferromagnet,
and performed magnetic susceptibility, specific heat, and thermal conductivity …

Doubts have been raised on the representation of chiral spin liquids exhibiting topological
order in terms of projected entangled pair states (PEPSs). Here, starting from a simple spin …

The pairing of interacting fermions leading to superfluidity has two limiting regimes: the
Bardeen-Cooper-Schrieffer (BCS) scheme for weakly interacting degenerate fermions and …

Spectral probes, such as neutron scattering, are crucial for characterizing excitations in
quantum many-body systems and the properties of quantum materials. Among the most …

In a recent study [Phys. Rev. X 10, 021042 (2020) 10.1103/PhysRevX. 10.021042], we
showed using large-scale density matrix renormalization group (DMRG) simulations on …

It is predicted that strongly interacting spins on a frustrated lattice may lead to a quantum
disordered ground state or even form a quantum spin liquid with exotic low-energy …
