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…
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…
Charge-2esuperconductivity from a disordered pair density wave
Julian May-Mann, Akshat Pandey, Steven A. Kivelson +1
We investigate the effects of disorder on a system that in the clean limit is a pair density wave (PDW) superconductor. The charge order of the clean PDW is inevitably lost (via Im…
Symmetry-determined generalized ferromagnetism in multi-valley electron fluids
Vladimir Calvera, Erez Berg, Steven A. Kivelson
Quantum electronic fluids with spin and valley degrees of freedom have a correlation driven tendency to flavor polarization (generalized ferromagnetism). To first order in the long…
Spin-glass state in nickelate superconductors
David R. Saykin, Martin Gonzalez, Jennifer Fowlie +3
Magneto-optical measurements in LaSrNiO and NdSrNiO reveal an intriguing new facet of infinite-layer nickelate superconducto…
