Gradient optimization of fermionic projected entangled pair states on directed lattices
Shao-Jun Dong, Chao Wang, Yongjian Han +2
The recently developed stochastic gradient method combined with Monte Carlo sampling techniques [PRB {\bf 95}, 195154 (2017)] offers a low scaling and accurate method to optimize t…
Dynamic-Disorder-Induced Enhancement of Entanglement in Photonic Quantum Walks
Qin-Qin Wang, Xiao-Ye Xu, Wei-Wei Pan +6
Entanglement generation in discrete time quantum walks is deemed to be another key property beyond the transport behaviors. The latter has been widely used in investigating the loc…
Measuring the winding number in a large-scale chiral quantum walk
Xiao-Ye Xu, Qin-Qin Wang, Wei-Wei Pan +8
We report the experimental measurement of the winding number in an unitary chiral quantum walk. Fundamentally, the spin-orbit coupling in discrete time quantum walks is implemented…
Measuring a Dynamical Topological Order Parameter in Quantum Walks
Xiao-Ye Xu, Qin-Qin Wang, Markus Heyl +9
Quantum processes of inherent dynamical nature, such as quantum walks (QWs), defy a description in terms of an equilibrium statistical physics ensemble. Up to now, it has remained…
Gapless spin liquid ground state of spin-1/2 - Heisenberg model on square lattices
Wen-Yuan Liu, Shaojun Dong, Chao Wang +4
The spin-1/2 - Heisenberg model on square lattices are investigated via the finite projected entangled pair states (PEPS) method. Using the recently developed gradient op…
PEPS++: Towards Extreme-scale Simulations of Strongly Correlated Quantum Many-particle Models on Sunway TainhuLight
Lixin He, Hong An, Chao Yang +10
The study of strongly frustrated magnetic systems has drawn great attentions from both theoretical and experimental physics. Efficient simulations of these models are essential for…
