Microfluidic and Nanofluidic Cavities for Quantum Fluids Experiments
A. Duh, A. Suhel, B. D. Hauer +4
The union of quantum fluids research with nanoscience is rich with opportunities for new physics. The relevant length scales in quantum fluids, 3He in particular, are comparable to…
Intense Electromagnetic Outbursts from Collapsing Hypermassive Neutron Stars
Luis Lehner, Carlos Palenzuela, Steven L. Liebling +2
We study the gravitational collapse of a magnetized neutron star using a novel numerical approach able to capture both the dynamics of the star and the behavior of the surrounding…
Quantum Computation with Coherent Spin States and the Close Hadamard Problem
Mark Adcock, Peter Hoyer, Barry C. Sanders
We study a model of quantum computation based on the continuously-parameterized yet finite-dimensional Hilbert space of a spin system. We explore the computational powers of this m…
Semimetal and Topological Insulator in Perovskite Iridates
Jean-Michel Carter, V. Vijay Shankar, M. Ahsan Zeb +1
The two-dimensional layered perovskite Sr2IrO4 was proposed to be a spin-orbit Mott insulator, where the effect of Hubbard interaction is amplified on a narrow J_{eff} = 1/2 band d…
Experimental methods of ultracold atomic physics
D. M. Stamper-Kurn, J. H. Thywissen
Experiments on solid-state materials and atomic quantum gases are increasingly investigating similar concepts in many-body quantum physics. Yet, the flavor of experiments on the ga…
Spin Ice: Magnetic Excitations without Monopole Signatures using Muon Spin Rotation
S. R. Dunsiger, A. A. Aczel, C. Arguello +13
Theory predicts the low-temperature magnetic excitations in spin ices consist of deconfined magnetic charges, or monopoles. A recent transverse-field (TF) muon spin rotation (muSR)…
NMR Characterization of Sulphur Substitution Effects in the K(x)Fe(2-y)Se(2-z)S(z) high Tc Superconductor
D. A. Torchetti, T. Imai, H. C. Lei +1
We present an NMR study of the effect of S substitution in the high Tc superconductor K(x)Fe(2-y)Se(2-z)S(z) in a temperature range up to 250 K. We present NMR Knight shift and nuc…
Importance of subleading corrections for the Mott critical point
Patrick Sémon, A. -M. S. Tremblay
The interaction-induced metal-insulator transition should be in the Ising universality class. Experiments on layered organic superconductors suggest that the observed critical endp…
Andreev nanoprobe of half-metallic CrO films using superconducting cuprate tips
C. S. Turel, I. J. Guilaran, P. Xiong +1
Superconducting tips of YBaCuO were used to perform point-contact Andreev reflection spectroscopy on half-metallic CrO thin films. At 4.2K, strong suppre…
Lateral imaging of the superconducting vortex lattice using Doppler-modulated scanning tunneling microscopy
I. Fridman, C. Kloc, C. Petrovic +1
By spatially mapping the Doppler effect of an in-plane magnetic field on the quasiparticle tunneling spectrum, we have laterally imaged the vortex lattice in superconducting 2H-NbS…
Low-temperature, high-density magneto-optical trapping of potassium using the open 4S-5P transition at 405 nm
D. C. McKay, D. Jervis, D. J. Fine +3
We report the laser cooling and trapping of neutral potassium on an open transition. Fermionic 40K is captured using a magneto-optical trap (MOT) on the closed 4S-4P transition at…
How Kondo Holes Create Intense Nanoscale Heavy-Fermion Hybridization Disorder
Mohammad H. Hamidian, Andrew R. Schmidt, Inês A. Firmo +8
Replacing a magnetic atom by a spinless atom in a heavy fermion compound generates a quantum state often referred to as a 'Kondo-hole'. No experimental imaging has been achieved of…
Effect of electron-phonon coupling on energy and density of states renormalizations of dynamically screened graphene
J. P. F. LeBlanc, J. P. Carbotte, E. J. Nicol
Electronic screening strongly renormalizes the linear bands which occur near the Dirac crossing in graphene. The single bare Dirac crossing is split into two individual Dirac-like…
Pseudogap temperature as a Widom line in doped Mott insulators
G. Sordi, P. Sémon, K. Haule +1
The pseudogap refers to an enigmatic state of matter with unusual physical properties found below a characteristic temperature in hole-doped high-temperature superconductors.…
