Probing the real-space density of spin-entangled electrons
Federico Pisani, Leonie Spitz, Libor VojáÄek +12
On the textbook example of an isolated antiferromagnetic Heisenberg dimer, we demonstrate that the magnetic form factor and the magnetic electron density distribution can be extrac…
Field-induced quasi-bound state within the two-magnon continuum of a square-lattice Heisenberg antiferromagnet
F. Elson, M. Nayak, A. A. Eberharter +14
Quantum magnets in two dimensions display strong quantum interaction effects even when magnetically ordered. Using the metal-organic framework material CuF(DO)(pyz), we…
Nuclear quadrupole interaction and zero first-order Zeeman transitions of Er in CaWO
Lewin Marsh, Yikai Yang, Cesare Mattiroli +5
We report microwave spectroscopy of Er doped in CaWO which reveals the hyperfine splitting of the erbium electronic ground state (, =15/2)…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. BiaÅo, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
Approximate resolution convolution function for fitting a dispersion gap measured on a triple-axis spectrometer
Emma Y. Lenander, Silas B. Schack, Kim Lefmann +1
We present an analytic convoluted-gap function, eq. 11 in the manuscript, for fitting dispersion gaps measured on triple-axis spectrometers (TAS). At the gap, the instrumental reso…
Impact of Electron Correlations on Infinite-Layer Cuprates and Nickelates
Xunyang Hong, Yuetong Wu, Ying Chan +20
Optimization of unconventional superconductivity involves a balance of interaction strengths. Precise determination of correlation strength across different material families is th…
