报告摘要：

Building quantum-mechanics based computation systems is one of the grand challenges of modern science and engineering.  Currently there is a major push for finding the most promising materials system that one can implement quantum mechanical algorithms.  An exciting candidate is a-RuCl3, first studied by the co-PI in 2014.  Since a-RuCl3 is a Mott insulator, direct electrical measurement is difficult.  Here we propose to develop a two-point ac magnetic susceptibility probe to couple to the entangled spin dynamics in the quantum spin liquid phase of a-RuCl3.  Given the known Kitaev parameters of the material, it is widely believed that this field-driven paramagnet is a new phase of matter, a quantum spin liquid.
