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 …

The nature of the randomness-induced quantum spin liquid state, the random-singlet state,
is investigated in two dimensions (2D) by means of the exact-diagonalization and the Hams …

Strongly enhanced quantum fluctuations often lead to a rich variety of quantum-disordered
states. Develo** approaches to enhance quantum fluctuations may open paths to realize …

Thermodynamic properties of the proton-mediated single component dimer-Mott insulator of
κ-H 3 (Cat-EDT-TTF) 2, which has a two-dimensional triangle lattice structure of S= 1/2 …

κ-H3 (Cat-EDT-TTF) 2 (H-TTF) is a hydrogen-bonded π-electron system which was found to
reveal C2/c symmetry at 50–293 K, while its isotopologue, κ-D3 (Cat-EDT-TTF) 2 (D-TTF) …

Spin-liquid behavior was recently suggested experimentally in the moderately one-
dimensional organic compound κ-H 3 (Cat-EDT-TTF) 2. This compound can be modeled by …

A purely organic material, κ-D3 (Cat-EDT-TTF) 2, undergoes a peculiar charge ordering
transition triggered by deuterium localization in hydrogen bonds between two-dimensional …

We present a new method to obtain a model Hamiltonian from first-principles calculations.
The effective interaction contained in the model is determined on the basis of random phase …

We theoretically investigated a significant contraction of the hydrogen-bonding O⋯ O
distance upon H/D substitution in our recently developed purely organic crystals, κ-H 3 (Cat …

We study the electronic and structural properties of the low-temperature ordered phase of
hydrogen-bonded molecular conductors, κ-D 3 (Cat-EDT-TTF) 2 and its selenium …
