Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

The Heisenberg triangular-lattice quantum spin liquid and its phase transitions to nearby
magnetic orders have received much theoretical attention, but clear experimental …

We consider multipartite states of qubits and prove that their bipartite quantum
entanglement, as quantified by the concurrence, satisfies a monogamy inequality …

We demonstrate how quantum entanglement can be directly witnessed in the quasi-1D
Heisenberg antiferromagnet KCuF 3. We apply three entanglement witnesses—one tangle …

By means of the time dependent density matrix renormalization group algorithm we study
the zero-temperature dynamics of the Von Neumann entropy of a block of spins in a …

The lack of methods to experimentally detect and quantify entanglement in quantum matter
impedes our ability to identify materials hosting highly entangled phases, such as quantum …

We consider systems of interacting spins and study the entanglement that can be localized,
on average, between two separated spins by performing local measurements on the …

Entanglement not only plays a crucial role in quantum technologies, but is key to our
understanding of quantum correlations in many-body systems. However, in an experiment …

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 …
