Learning Inhomogeneous Heisenberg Hamiltonians in Nanographene Spin Chains

Greta Lupi, Saketh Ravuri, Chenxiao Zhao +9

Inferring microscopic Hamiltonians from experimental data is a central challenge in quantum materials and quantum simulation. In low-dimensional spin systems, exchange interactions…

On determining the energy dispersion of spin excitations with scanning tunneling spectroscopy

J. C. G. Henriques, Chenxiao Zhao, G. Catarina +3

Conventional methods to measure the dispersion relations of collective spin excitations involve probing bulk samples with particles such as neutrons, photons or electrons, which ca…

Gapless spin excitations in nanographene-based antiferromagnetic spin-1/2 Heisenberg chains

Chenxiao Zhao, Lin Yang, João C. G. Henriques +8

Haldane's seminal work established two fundamentally different types of excitation spectra for antiferromagnetic Heisenberg quantum spin chains: gapped excitations in integer-spin…
