Accessing Excitation of Many-body Systems via Single-Mode Approximation within Quantum Monte Carlo Simulations
Yan Liu, Kemeng Wu, Shutao Liu +4
We extend the single-mode Approximation (SMA) into quantum Monte Carlo simulations to provides an efficient and fast method to obtain the dynamical dispersion of quantum many-body…

Six-component pairing instability in the SU(4) - chain
Jia-Cheng He, Jun-Hao Zhang, Jie Lou +1
We use the density matrix renormalization group (DMRG) method to study the SU(4) - chain. We find that, in addition to the conventional repulsive Luttinger liquid phase and p…
