Learning Autonomous Vehicle Safety Concepts from Demonstrations
Karen Leung, Sushant Veer, Edward Schmerling +1
Evaluating the safety of an autonomous vehicle (AV) depends on the behavior of surrounding agents which can be heavily influenced by factors such as environmental context and infor…
A quantum spin liquid phase in the Kitaev-Hubbard model
Shaojun Dong, Hao Zhang, Chao Wang +3
The quantum spin liquid (QSL) state has been searched intensively in Kitaev-like materials, such as the Iridium oxides IrO and -RuCl. The half-filled Kitaev-Hubbard…
Projected entangled pair states study of anisotropic-exchange magnets on triangular lattice
Meng Zhang, Chao Wang, Shaojun Dong +3
The anisotropic-exchange spin-1/2 model on a triangular lattice has been used to describe the rare-earth chalcogenides, which may have exotic ground states. We investigate the quan…
Simulation of the Ring-exchange Models with Projected Entangled Pair States
Chao Wang, Shaojun Dong, Yongjian Han +1
Algorithms to simulate the ring-exchange models using the projected entangled pair states (PEPS) are developed. We generalize the imaginary time evolution (ITE) method to optimize…
Symmetry Protected Topological Phases in Spin Ladders with Two-body Interactions
Zheng-Xin Liu, Zhen-Biao Yang, Yong-Jian Han +2
Spin-1/2 two-legged ladders respecting inter-leg exchange symmetry and D2 spin rotation symmetry have new symmetry protected topological (SPT) phases which are different from the H…
Tensor network simulation of phase diagram of frustrated J1-J2 Heisenberg model on a checkerboard lattice
Yang-hao Chan, Yong-jian Han, Luming Duan
We use the recently developed tensor network algorithm based on infinite projected entangled pair states (iPEPS) to study the phase diagram of frustrated antiferromagnetic J1-J2 He…
Supersolid and charge density-wave states from anisotropic interaction in an optical lattice
Y. -H. Chan, Y. -J. Han, L. -M. Duan
We show anisotropy of the dipole interaction between magnetic atoms or polar molecules can stabilize new quantum phases in an optical lattice. Using a well controlled numerical met…
Stabilization of the p-wave superfluid state in an optical lattice
Y. -J. Han, Y. -H. Chan, W. Yi +4
It is hard to stabilize the p-wave superfluid state of cold atomic gas in free space due to inelastic collisional losses. We consider the p-wave Feshbach resonance in an optical la…
A scheme for demonstration of fractional statistics of anyons in an exactly solvable model
Y. -J. Han, R. Raussendorf, L. -M. Duan
We propose a scheme to demonstrate fractional statistics of anyons in an exactly solvable lattice model proposed by Kitaev that involves four-body interactions. The required many-b…
