The Future of the Correlated Electron Problem
A. Alexandradinata, N. P. Armitage, Andrey Baydin +44
A central problem in modern condensed matter physics is the understanding of materials with strong electron correlations. Despite extensive work, the essential physics of many of t…
Spinon Confinement and a Sharp Longitudinal Mode in YbPtPb in Magnetic Fields
W. J. Gannon, I. A. Zaliznyak, L. S. Wu +7
The fundamental excitations in an antiferromagnetic chain of spins-1/2 are spinons, de-confined fractional quasiparticles that when combined in pairs, form a triplet excitation con…
Intermediate valence in single crystalline YbSiAl
W. J. Gannon, K. Chen, M. Sundermann +8
YbSiAl may be a prototype for exploring different aspects of the Shastry-Sutherland lattice, formed by planes of orthogonally coupled Yb ions. Measurements of the magnetic…
A Local Quantum Phase Transition in YFeAl
W. J. Gannon, L. S Wu, I. A. Zaliznyak +5
A phase transition occurs when correlated regions of a new phase grow to span the system and the fluctuations within the correlated regions become long-lived. Here we present neutr…
Quantum critical singularities in two-dimensional metallic XY ferromagnets
Chandra M. Varma, W. J. Gannon, M. C. Aronson +2
An important problem in contemporary physics concerns quantum-critical fluctuations in metals. A scaling function for the momentum, frequency, temperature and magnetic field depend…
Orbital-Exchange and Fractional Quantum Number Excitations in an f-electron Metal YbPtPb
L. S. Wu, W. J. Gannon, I. A. Zaliznyak +9
Exotic quantum states and fractionalized magnetic excitations, such as spinons in one-dimensional chains, are generally viewed as belonging to the domain of 3d transition metal sys…
