Quantum Tapestries Within each of Nature's crystals is an exotic quantum world of electrons weaving to and fro. Each crystal has its own unique tapestry, as varied as the crystals themselves. In some crystals the electrons weave an orderly quilt. Within others the electrons are seemingly entwined in an entangled web of quantum motion. In thi stalk I will describe the ongoing efforts to disentangle even Nature's most intricate quantum embroidery. Cutting-edge quantum many-body simulations together with recent ideas from quantum information theory, such as entangelment entropy, are enabling a coherent picture to emerge.
