Tree tensor network impurity solver based on Cayley-tree mapping
Bo Zhan, Jia-Lin Chen, Zhen Fan +1
We introduce a tree tensor network (TTN) impurity solver that enables highly efficient and accurate real-time simulations of quantum impurity models. By decomposing a noninteractin…
Efficient simulation of low-entanglement bosonic Gaussian states in polynomial time
Tong Liu, Hui-Ke Jin, Tao Xiang +1
Bosonic Gaussian states are ubiquitous in quantum optics and condensed matter physics. While they are efficiently handled within the Gaussian formalism, sampling requires calculati…
Deconfined Quantum Critical Point in Quantum Hall Bilayers
Guangyu Yu, Tao Xiang, Zheng Zhu
Deconfined quantum critical points (DQCPs) represent an unconventional class of quantum criticality beyond the Landau-Ginzburg-Wilson-Fisher paradigm. Nevertheless, both their theo…
An efficient quantum circuits optimizing scheme compared with QISKit
Xin Zhang, Hong Xiang, Tao Xiang +2
Recently, the development of quantum chips has made great progress-- the number of qubits is increasing and the fidelity is getting higher. However, qubits of these chips are not a…
Mermin-Wagner physics, (H,T) phase diagram, and candidate quantum spin-liquid phase in the spin-1/2 triangular-lattice antiferromagnet Ba8CoNb6O24
Y. Cui, J. Dai, P. Zhou +11
BaCoNbO presents a system whose Co ions have an effective spin 1/2 and construct a regular triangular-lattice antiferromagnet (TLAFM) with a very large interl…
Experimental Approach to the Thermodynamics of the Pure Two-Dimensional Spin-1/2 Triangular Lattice Antiferromagnet in Ba8CoNb6O24
Y. Cui, J. Dai, P. Zhou +10
Frustrated quantum magnets pose well-defined questions concerning quantum fluctuation effects and the nature of the many-body wavefunction, which challenge theory, numerics, experi…
