Chebyshev pseudosite matrix product state approach for cluster perturbation theory
Pei-Yuan Zhao, Ke Ding, Shuo Yang
We introduce the Chebyshev pseudosite matrix product state approach (ChePSMPS) as a solver for cluster perturbation theory (CPT), crucial for simulating spectral functions in two-d…

Fractonic Higher-Order Topological Phases in Open Quantum Systems
Jian-Hao Zhang, Ke Ding, Shuo Yang +1
In this work, we study the generalization of decohered average symmetry-protected topological phases to open quantum systems with a combination of subsystem symmetries and global s…

Chebyshev pseudosite matrix product state approach for the spectral functions of electron-phonon coupling systems
Pei-Yuan Zhao, Ke Ding, Shuo Yang
The electron-phonon (-ph) coupling system often has a large number of phonon degrees of freedom, whose spectral functions are numerically difficult to compute using matrix produ…
