Chiral Spin Liquid in Rydberg Atom Arrays
Yu-Feng Mao, Shicheng Ma, Yong Xu
Despite long-standing theoretical interest, the chiral spin liquid, a topologically ordered phase, has yet to be observed experimentally. Here we surprisingly find its emergence in…

Left-left-right-right magnetic order in spin-1/2 Kitaev-Heisenberg chain
Wang Yang, Chao Xu, Shicheng Ma +2
In this work, we perform a combination of analytical and numerical studies on the phase diagram of the spin-1/2 Kitaev-Heisenberg chain in the region of negative Kitaev and positiv…
