Recent numerical simulations find a possible chiral spin-liquid state in the intermediate coupling regime of the triangular lattice Hubbard model. Here we provide a simple picture for its origin in terms of a bosonic resonating valence bond (RVB) des

Although it is well accepted that the spin-$1/2$ triangular lattice Heisenberg antiferromagnet (TLHAF) has a long-range ordered ground state, a thorough understanding of its spin dynamics is still missing. While the linear spin wave theory (LSWT) pre

We examine applicability of the valence bond basis correlator product state ansatz, equivalent to the restricted Boltzmann machine quantum artificial neural network ansatz, and variational Monte Carlo method for direct optimization of excited energy

We investigate the phenomenon of high-temperature superconductivity within a strong coupling perspective. The occurence is traced to a quantum critical point that is in the phase diagram of the plaquette's t; t0-Hubbard model. We develop a bottom-up

We present the results of a high-resolution low-temperature synchrotron structural study of the nitrogen-containing analogue of cupric oxide, copper carbodiimide (CuNCN). The material clearly manifests a surprising nonmonotonous behavior of the a lat

Density functional theory calculations in different cluster models, the largest one K38(C60)23 with 1,418 atoms, combined with the resonating valence-bond theory show that superconductivity in K3C60 involves interaction of C60 with K+, K0, and K− i

Discovery of high T c superconductivity in La2−x Ba x CuO4 by Bednorz and Muller in 1986 was a breakthrough in the 75-year long search for new superconductors. Since then new high T c superconductors, not involving copper, have also been discovered

Resonating valence bond theory combined with DFT calculations permit to build a simple model for the dissociation of H 2 on palladium surface. Based on analysis of the electron transfer and total energy for different geometries of the Pd 2 –H 2 and

Superconductivity in an uncompensated boron doped diamond, a very recent observation, is strikingly close to an earlier observation of Anderson-Mott insulator to metal transition, prompting us to suggest an electron correlation driven superconductivi
