报告摘要:The kagome lattice is an exceptional platform for exploring novel many-body states, owing to its distinctive lattice and electron structures. Motivated by very recent experimental observations of the 1/9-magnetization plateaus in YCu3(OH)6+xBr3−x and YCu3(OD)6+xBr3−x, our study delves into the magnetic-field-induced phase transitions in the nearest-neighbor antiferromagnetic Heisenberg model on the kagome lattice using the variational Monte Carlo technique.
