Description |
Research over the last three decades shows that several low temperature phases of matter cannot be characterized within the paradigm of spontaneous symmetry breaking. Hence, a much wider structure of understanding and classifying phases is being currently pursued. Studies in frustrated magnets have provided examples of such unconventional phases and indicated plausible material candidates where such phases may be realized. These are systems of interacting spins, that fail to develop magnetic or other orders at low temperature and yet remain highly correlated. In this talk, I shall discuss such phases, dubbed as quantum spin liquids, and show that they have rich low energy properties that are very different from those of the ordered phases; recent developments in our understanding of quantum spin liquids; and, some experimental signatures in context of concrete material candidates. |
