Nontrivial quantized Berry phases for itinerant spin liquids
Isao Maruyama, Yasuhiro Hatsugai
Quantized Berry phases as local order parameters in t-J models are studied. A texture pattern of the local order parameters is topologically stable due to the quantization of non-A…

Levitation and percolation in quantum Hall systems with correlated disorder
Hui Song, Isao Maruyama, Yasuhiro Hatsugai
We investigate the integer quantum Hall system in a two dimensional lattice model with spatially correlated disorder by using the efficient method to calculate the Chern number pro…
