Correcting Aberrations of a Transverse-Field Neutron Resonance Spin Echo Instrument
Stephen J. Kuhn, Sam McKay, Fankang Li +5
The neutron resonance spin echo (NRSE) technique has the potential to increase the Fourier time and energy resolution in neutron scattering by using radio-frequency (rf) neutron sp…
Reversible ordering and disordering of the vortex lattice in UPt3
K. E. Avers, S. J. Kuhn, A. W. D. Leishman +7
When studied by small-angle neutron scattering the vortex lattice (VL) in UPt3 undergoes a gradual disordering as a function of time due to 235U fission. This temporarily heats reg…
Neutron State Entanglement with Overlapping Paths
S. J. Kuhn, S. McKay, J. Shen +12
The development of direct probes of entanglement is integral to the rapidly expanding field of complex quantum materials. Here we test the robustness of entangled neutrons as a qua…
Incommensurate two-dimensional checkerboard charge density wave in the low dimensional superconductor Ta4Pd3Te16
Zhenzhong Shi, S. J. Kuhn, F. Flicker +9
We report the observation of a two-dimensional (2D) checkerboard charge density wave (CDW) in the low-dimensional superconductor Ta4Pd3Te16. By determining its CDW properties acros…
An Operator Analysis of Contextuality Witness Measurements for Multimode-Entangled Single Neutron Interferometry
Shufan Lu, Abu Ashik Md. Irfan, Jiazhou Shen +5
We develop an operator-based description of two types of multimode-entangled single-neutron quantum optical devices: Wollaston prisms and radio-frequency spin flippers in inclined…
Unveiling contextual realities by microscopically entangling a neutron
J. Shen, S. J. Kuhn, R. M. Dalgliesh +13
The development of qualitatively new measurement capabilities is often a prerequisite for critical scientific and technological advances. The dramatic progress made by modern probe…
Structural studies of metastable and equilibrium vortex lattice domains in MgB2
E. R. Louden, A. W. D. Leishman, C. Rastovski +5
The vortex lattice in MgB2 is characterized by the presence of long-lived metastable states, which arise from cooling or heating across the equilibrium phase boundaries. A return t…
Structural Transition Kinetics and Activated Behavior in the Superconducting Vortex Lattice
E. R. Louden, C. Rastovski, S. J. Kuhn +5
Using small-angle neutron scattering, we investigated the behavior of a metastable vortex lattice state in MgB2 as it is driven towards equilibrium by an AC magnetic field. This sh…
Vortex lattices and broken time reversal symmetry in the topological superconductor UPt3
K. E. Avers, W. J. Gannon, S. J. Kuhn +8
The topological superconductor UPt3, has three distinct vortex phases, a strong indication of its unconventional character. Using small-angle neutron scattering we have probed the…
Anisotropy and multiband superconductivity in Sr2RuO4
S. J. Kuhn, W. Morgenlander, E. R. Louden +8
Despite numerous studies the exact nature of the order parameter in superconducting Sr2RuO4 remains unresolved. We have extended previous small-angle neutron scattering studies of…
Persistent Magnetism in Silver-doped BaFe2As2 Crystals
Li Li, Huibo Cao, David S. Parker +2
We investigate the thermodynamic and transport properties of silver-substituted BaFe2As2 (122) crystals, up to ~4.5%. Similar to other transition-metal substitutions in 122, Ag dim…
FeS: Structure and Composition Relations to Superconductivity and Magnetism
S. J. Kuhn, M. K. Kidder, W. M. Chance +9
Structure and composition of iron chalcogenides have a delicate relationship with magnetism and superconductivity. In this report we investigate the iron sulfide layered tetragonal…
Simultaneous Evidence for Pauli Paramagnetic Effects and Multiband Superconductivity in KFeAs by Small-Angle Neutron Scattering Studies of the Vortex Lattice
S. J. Kuhn, H. Kawano-Furukawa, E. Jellyman +11
We study the intrinsic anisotropy of the superconducting state in KFeAs, using small-angle neutron scattering to image the vortex lattice as the applied magnetic field is r…
