New perspectives on Density-Matrix Embedding Theory
Alicia Negre, Fabian Faulstich, Raehyun Kim +3
Quantum embedding methods enable the study of large, strongly correlated quantum systems by (usually self-consistent) decomposition into computationally manageable subproblems, in…
Ab initio quantum many-body description of superconducting trends in the cuprates
Zhi-Hao Cui, Junjie Yang, Johannes Tölle +9
Using a systematic ab initio quantum many-body approach that goes beyond low-energy models, we directly compute the superconducting pairing order and estimate the pairing gap of se…
Interacting models for twisted bilayer graphene: a quantum chemistry approach
Fabian M. Faulstich, Kevin D. Stubbs, Qinyi Zhu +7
The nature of correlated states in twisted bilayer graphene (TBG) at the magic angle has received intense attention in recent years. We present a numerical study of an interacting…
On the pure state -representability of density matrix embedding theory
Fabian M. Faulstich, Raehyun Kim, Zhi-Hao Cui +3
Density matrix embedding theory (DMET) formally requires the matching of density matrix blocks obtained from high-level and low-level theories, but this is sometimes not achievable…
Reinforcement Learning for Many-Body Ground-State Preparation Inspired by Counterdiabatic Driving
Jiahao Yao, Lin Lin, Marin Bukov
The quantum alternating operator ansatz (QAOA) is a prominent example of variational quantum algorithms. We propose a generalized QAOA called CD-QAOA, which is inspired by the coun…
