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…
Optically detected magnetic resonance of nitrogen vacancies in a diamond anvil cell using designer diamond anvils
L. Steele, M. Lawson, M. Onyszczak +11
Optically detected magnetic resonance of nitrogen vacancy centers in diamond offers novel routes to both DC and AC magnetometry in diamond anvil cells under high pressures ( GP…
Nuclear Magnetic Resonance Probe Head Design for Precision Strain Control
T. Kissikov, R. Sarkar, B. T. Bush +3
We present the design and construction of an NMR probe to investigate single crystals under strain at cryogenic temperatures. The probe head incorporates a piezoelectric-based appa…
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…
