Ground state phase diagram of the repulsive fermionic Hubbard model on the square lattice from weak-coupling
Fedor Simkovic, Xuan-Wen Liu, Youjin Deng +1
We obtain a complete and exact in the weak-coupling limit () ground state phase diagram of the repulsive fermionic Hubbard model on the square lattice for filling…
Realization of Two-Dimensional Spin-orbit Coupling for Bose-Einstein Condensates
Zhan Wu, Long Zhang, Wei Sun +7
Cold atoms with laser-induced spin-orbit (SO) interactions provide intriguing new platforms to explore novel quantum physics beyond natural conditions of solids. Recent experiments…
Spin-Ice State of the Quantum Heisenberg Antiferromagnet on the Pyrochlore Lattice
Yuan Huang, Kun Chen, Youjin Deng +2
We study the low-temperature physics of the -symmetric spin- Heisenberg antiferromagnet on a pyrochlore lattice and find fingerprint evidence for the thermal spin-ice s…
Clique percolation in random graphs
Ming Li, Youjin Deng, Bing-Hong Wang
As a generation of the classical percolation, clique percolation focuses on the connection of cliques in a graph, where the connection of two -cliques means that they share at l…
Adaptive Multi-GPU Exchange Monte Carlo for the 3D Random Field Ising Model
C. A. Navarro, Wei Huang, Youjin Deng
We present an adaptive multi-GPU Exchange Monte Carlo method designed for the simulation of the 3D Random Field Model. The algorithm design is based on a two-level parallelization…
The Massive Goldstone (Higgs) mode in two-dimensional ultracold atomic lattice systems
Longxiang Liu, Kun Chen, Youjin Deng +3
We discuss how to reveal the massive Goldstone mode, often referred to as the Higgs amplitude mode, near the Superfluid-to-Insulator quantum critical point (QCP) in a system of two…
