Superconducting valence bond fluid in lightly doped eight-leg cylinders

HC Jiang, SA Kivelson, DH Lee - Physical Review B, 2023‏ - APS
Superconductivity in doped quantum paramagnets has been a subject of long theoretical
inquiry. In this work, we report a density matrix renormalization group study of lightly doped …

Dynamical defects in a two-dimensional Wigner crystal: Self-do** and kinetic magnetism

KS Kim, I Esterlis, C Murthy, SA Kivelson - Physical Review B, 2024‏ - APS
We study the quantum dynamics of interstitials and vacancies in a two-dimensional Wigner
crystal (WC) using a semiclassical instanton method that is asymptotically exact at low …

Resonating valence bond states in an electron-phonon system

Z Han, SA Kivelson - Physical Review Letters, 2023‏ - APS
We study a simple electron-phonon model on square and triangular versions of the Lieb
lattice using an asymptotically exact strong coupling analysis. At zero temperature and …

Frustrated quantum magnetism on complex networks: What sets the total spin

G Preethi, S Dutta - arxiv preprint arxiv:2403.09116, 2024‏ - arxiv.org
Consider equal antiferromagnetic Heisenberg interactions between qubits sitting at the
nodes of a complex, nonbipartite network. We ask the question: How does the network …

Exact hole-induced flavor singlets in certain Hubbard models

KS Kim, H Katsura - Physical Review Research, 2024‏ - APS
We prove that the motion of a single hole induces SU (N) flavor singlets in the U=∞ SU
(N)(Fermi) Hubbard model on a Husimi-like tree graph. The result is generalized to certain tJ …

Spin-charge separation and resonant valence bond spin liquid in a frustrated doped Mott insulator
