Quantum Criticality in the infinite-range Transverse Field Ising Model
Nicholas Curro, Kaeshav Danesh, Rajiv R. P. Singh
We study quantum criticality in the infinite range Transverse-Field Ising Model. We find subtle differences with respect to the well-known single-site mean-field theory, especially…
Local nematic susceptibility in stressed BaFeAs from NMR electric field gradient measurements
T. Kissikov, R. Sarkar, M. Lawson +10
The electric field gradient (EFG) tensor at the As site couples to the orbital occupations of the As p-orbitals and is a sensitive probe of local nematicity in BaFeAs$_2…
First-Order Reversal Curves of the Magnetostructural Phase Transition in FeTe
M. K. Frampton, J. Crocker, D. A. Gilbert +5
We apply the first-order reversal curve (FORC) method, borrowed from studies of ferromagnetic materials, to the magneto-structural phase transition of FeTe. FORC measurements revea…
Impurities near an Antiferromagnetic-Singlet Quantum Critical Point
T. Mendes, N. Costa, G. Batrouni +4
Heavy fermion systems, and other strongly correlated electron materials, often exhibit a competition between antiferromagnetic (AF) and singlet ground states. Using exact Quantum M…
Coexistence of cluster spin glass and superconductivity in Ba(FeCo)As for
A. P. Dioguardi, J. Crocker, A. C. Shockley +9
We present 75As nuclear magnetic resonance data from measurements of a series of Ba(FeCo)As crystals with that reveals the coexistence…
NMR evidence for spin fluctuations in the bilayer nickelate La3Ni2O6
N. apRoberts-Warren, J. Crocker, A. P. Dioguardi +5
We report nuclear magnetic resonance data in the bilayer nickelate La3Ni2O6. This material belongs to a family of low valence nickel oxides with square planar coordination of the N…
