On a large class of lattices (such as the sawtooth chain, the kagome and the pyrochlore
lattices), the quantum Heisenberg and the repulsive Hubbard models may host a completely …

One novel arena for designing superconductors with high TC is the flat band system. A basic
idea is that flat bands, arising from quantum mechanical interference, give unique …

The natural mineral azurite Cu 3 (CO 3) 2 (OH) 2 is a frustrated magnet displaying unusual
and controversially discussed magnetic behavior. Motivated by the lack of a unified …

To explore whether a flat-band system can accommodate superconductivity, we consider
repulsively interacting fermions on the diamond chain, a simplest possible quasi-one …

Ground-state and finite-temperature properties of the mixed spin-and spin-S Ising–
Heisenberg diamond chains are examined within an exact analytical approach based on the …

The quantum teleportation plays an important role in quantum information process, in this
sense, the quantum entanglement properties involving an infinite chain structure is quite …

We present a specific heat and inelastic neutron scattering study in magnetic fields up into
the 1/3 magnetization plateau phase of the diamond chain compound azurite Cu 3 (CO 3) 2 …

Most quantum entanglement investigations are focused on two qubits or some finite (small)
chain structure, since the infinite chain structure is a considerably cumbersome task …

We study a three-leg spin-1/2 ladder with geometrically frustrated interleg interactions. We
call this model an anisotropic triangular-strip (ATS) model. We numerically and field …

The entanglement quantum properties of a spin-1/2 Ising–Heisenberg model on a
symmetrical diamond chain were analyzed. Due to the separable nature of the Ising-type …
