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 …

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

The detection and certification of entanglement and quantum correlations in materials is of
fundamental and far‐reaching importance, and has seen significant recent progress. It …

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

We explore the local quantum coherence and the local quantum uncertainty, based on
Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in …

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 …

Understanding quantum materials—solids in which interactions among constituent electrons
yield a great variety of novel emergent quantum phenomena—is a forefront challenge in …

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 …

Many-body entanglement in condensed matter systems can be diagnosed from equilibrium
response functions through the use of entanglement witnesses and operator-specific …

Isotropic XX models of one-dimensional spin-1/2 chains are investigated with the aim to
elucidate the formal structure and the physical properties that allow these systems to act as …
