Quantum Hall Liquids Coupled to Dynamical Electromagnetism
T. H. Hansson, Qing-Dong Jiang, S. A. Kivelson +1
We investigate the effect on a Quantum Hall (QH) liquid of its coupling to 3+1 dimensional dynamical electromagnetism, which renders the system gapless. We calculate both the Hall…
Competing states in the triangular-lattice - Heisenberg model: a dynamical density-matrix renormalization group study
Shengtao Jiang, Steven R. White, Steven A. Kivelson +1
Previous studies of the triangular-lattice -- Heisenberg antiferromagnet have inferred the existence of a non-magnetic ground-state phase for an intermediate rang…
Emergence of Fermi-liquid and BCS physics in overdoped cuprates
B. J. Ramshaw, Steven A. Kivelson
Cuprates are the paradigmatic `unconventional' superconductors: their critical temperature is much higher than can be expected from phonon-mediated pairing; the superconducting gap…
Competition between charge-density-wave and superconducting orders on eight-leg square Hubbard cylinders
Hong-Chen Jiang, Thomas P. Devereaux, Steven A. Kivelson
The issue of whether -wave superconductivity (SC) occurs in the square-lattice Hubbard model with of order of the bandwidth has been one of the most debated issues to emerge…
Expert Evaluation of LLM World Models: A High- Superconductivity Case Study
Haoyu Guo, Maria Tikhanovskaya, Paul Raccuglia +20
Large Language Models (LLMs) show great promise as a powerful tool for scientific literature exploration. However, their effectiveness in providing scientifically accurate and comp…
Pair-density-wave phase of strongly interacting electrons on the triangular lattice: A variational Monte Carlo study
Jiucai Wang, Wen Sun, Hao-Xin Wang +3
A robust theory of the mechanism of pair density wave (PDW) superconductivity (i.e. where Cooper pairs have nonzero center of mass momentum) remains elusive. Here we explore the tr…
