Excited state calculations using phaseless auxiliary-field quantum Monte Carlo: potential energy curves of low lying C2 singlet states
Wirawan Purwanto, Shiwei Zhang, Henry Krakauer
We show that the recently developed phaseless auxiliary-field quantum Monte Carlo (AFQMC) method can be used to study excited states, providing an alternative to standard quantum c…

Spatially inhomogeneous phase in the two-dimensional repulsive Hubbard model
Chia-Chen Chang, Shiwei Zhang
Using recent advances in auxiliary-field quantum Monte Carlo techniques and the phaseless approximation to control the sign/phase problem, we determine the equation of state in the…
