Autor: Liu, Dong-Xu, Xu, Wei, Zhang, Xue-Feng

Publikováno v: Published in Chin. Phys. B 33, 037509 (2024)

In the quantum Monte Carlo (QMC) method, the Pseudo-Random Number Generator (PRNG) plays a crucial role in determining the computation time. However, the hidden structure of the PRNG may lead to serious issues such as the breakdown of the Markov proc

Publikováno v: Journal of Harbin University of Science and Technology, Pp 21-26 (2017)

In order to improve the efficiency of Z/Q-Z source inverter and output current quality，reduce the harmonic distortion rate of grid-connected current，the control strategy of grid-connected current is applied to the Z/Q-Z source inverter. The deadb

Deconfined quantum phase transition on the kagome lattice: Distinct velocities of spinon and string excitations

Autor: Liu, Dong-Xu, Xiong, Zijian, Xu, Yining, Zhang, Xue-Feng

Publikováno v: Published in Phys. Rev. B 109, L140404 (2024)

Deconfined quantum phase transition (DQPT) provides an extraordinary possibility of the quantum phase transition beyond the Ginzburg-Landau paradigm, which is interwoven with numerous exotic phenomena of the strongly correlated quantum many-body syst

Quantum tricriticality of incommensurate phase induced by quantum domain walls in frustrated Ising magnetism

Autor: Zhou, Zheng, Liu, Dong-Xu, Yan, Zheng, Chen, Yan, Zhang, Xue-Feng

Publikováno v: SciPost Phys. 14, 037 (2023)

Incommensurability plays a critical role in many strongly correlated systems. In some cases, the origin of such exotic order can be theoretically understood in the framework of 1d line-like topological excitations known as ``quantum strings''. Here w
