简介: |
A quantum spin liquid (QSL), featuring long-range spin entanglement, is a manifestation of
many-body problems. Such states host a zoo of exotic phenomena beyond Landau’s
paradigm, despite their simple microscopic constitutes. The past decade has witnessed a
great adventure in this field thanks to the discovery of several promising compounds. I will
start with introducing basic concepts followed by an exhibition of recent experimental and
theoretical breakthroughs. The limitations of past investigations will be addressed with an eye
towards stronger experimental evidence. Further developments of QSL physics require a
close collaboration between experimentalists and theorists. Successful harness of
unconventional properties in QSLs will be best achieved utilizing a combination of state-of-theart
measurement techniques.
报告人简介：
Dr. Tian-Heng Han (韩天亨) is a distinguished postdoctoral fellow at the University of Chicago and Argonne National Laboratory in Chicago, USA. He graduated from the Hong Kong University of Science and Technology in 2006 and received his Ph.D. in experimental condensed matter physics from MIT in 2012. His researches focus on the study of quantum magnets using a variety of techniques, such as single crystal growth, neutron and synchrotron x-ray scatterings, calorimetry and magnetometry. His observation of fractionalized spin excitations on a 2D frustrated magnet marks the best evidence so far of a quantum spin liquid state. |
