Kitaev model on a quantum computer using VQE with Majorana fermions.
Quantum-spin liquids are exotic phases characterized by the absence of magnetic ordering even at the lowest temperatures and by the occurrence of fractionalized spin excitations. Among those, Kitaev spin liquids are most fascinating as they belong to the rare class of model systems, that can be solved analytically by decomposing localized spins. Electron-phonon coupling affects the properties of two-dimensional 2D materials significantly, leading to a series of novel phenomena. Inelastic light scattering provides a powerful experimental tool to explore electron-phonon interaction in 2D materials. This review gives an overview of the basic theory and experimental advances of electron-phonon coupling in 2D materials detected by Raman.

A quantum spin liquid QSL is a unique type of spin liquid where strong quantum fluctuations prevent spins from ordering, which thus remain in a disordered liquid-like state even near absolute 0 1, 2.Previous studies have shown that QSL states tend to emerge in low-spin geometrically frustrated systems, in which the interactions among the limited magnetic degrees of freedom are restricted.

Concept and realization of Kitaev quantum spin liquids.
Nearly two decades ago, Alexei Kitaev proposed a model for spin- particles with bond-directional interactions on a two-dimensional honeycomb lattice which had the potential to host a quantum spin-liquid ground state. This work initiated numerous investigations to design and synthesize materials that would physically realize the Kitaev Hamiltonian. Due to the combination of a substantial spin-orbit coupling and correlation effects, iridium oxides hold a prominent place in the search for novel quantum states of matter, including, e.g., Kitaev spin liquids and topological Weyl states. We establish the promise of the very recently synthesized hyper-honeycomb iridate -Li2IrO3 in this regard.

Three-dimensional Kitaev models -- generalizations of the well known exactly solvable Kitaev honeycomb model -- exhibit a rich variety of quantum spin liquid phases. Their fractionalized excitations are Majorana fermions that may form topological band structures. These can be enriched by lattice symmetries, as shown in the present work. In particular, the authors propose two new instances of.

Kitaev#x27;s honeycomb lattice spin model is a remarkable exactly solvable model, which has a particular type of spin liquid Kitaev spin liquid as the ground state.
