The light-matter correlation energy functional of the cavity-coupled two-dimensional electron gas via quantum Monte Carlo simulations
Lukas Weber, Miguel A. Morales, Johannes Flick +2
We perform extensive simulations of the two-dimensional cavity-coupled electron gas in a modulating potential as a minimal model for cavity quantum materials. These simulations are…
Re-anchoring Quantum Monte Carlo with Tensor-Train Sketching
Ziang Yu, Shiwei Zhang, Yuehaw Khoo
We propose a novel algorithm for calculating the ground-state energy of quantum many-body systems by combining auxiliary-field quantum Monte Carlo (AFQMC) with tensor-train sketchi…
The two-dimensional homogeneous electron gas with symmetric dual-gate screening: exchange-correlation functional and other ground-state properties
Yiqi Yang, Yubo Yang, Kun Chen +2
The two-dimensional (2D) homogeneous electron gas (HEG) is a fundamental model in quantum many-body physics. It is important to theoretical and computational studies, where exchang…
Phaseless auxiliary-field quantum Monte Carlo method for cavity-QED matter systems
Lukas Weber, Leonardo dos Anjos Cunha, Miguel A. Morales +2
We present a generalization of the phaseless auxiliary-field quantum Monte Carlo (AFQMC) method to cavity quantum-electrodynamical (QED) matter systems. The method can be formulate…
Ferromagnetic semimetal and charge-density wave phases of interacting electrons in a honeycomb moiré potential
Yubo Yang, Miguel A. Morales, Shiwei Zhang
The exploration of quantum phases in moiré systems has drawn intense experimental and theoretical efforts. The realization of honeycomb symmetry has been a recent focus. The combin…
Ground state phases of the two-dimension electron gas with a unified variational approach
Conor Smith, Yixiao Chen, Ryan Levy +3
The two-dimensional electron gas (2DEG) is a fundamental model, which is drawing increasing interest because of recent advances in experimental and theoretical studies of 2D materi…
