Spin frustration and magnetic ordering in triangular lattice antiferromagnet CaCoNbO
J. Dai, P. Zhou, P. S. Wang +5
We synthesized a quasi-two-dimensional distorted triangular lattice antiferromagnet CaCoNbO, in which the effective spin of Co is 1/2 at low temperatures, whose…
Expansion of the tetragonal magnetic phase with pressure in the iron-arsenide superconductor Ba{1-x}KxFe2As2
E. Hassinger, G. Gredat, F. Valade +11
In the temperature-concentration phase diagram of most iron-based superconductors, antiferromagnetic order is gradually suppressed to zero at a critical point, and a dome of superc…
Refrustration and competing orders in the prototypical Dy2Ti2O7 spin ice material
P. Henelius, T. Lin, M. Enjalran +6
Spin ices, frustrated magnetic materials analogous to common water ice, are exemplars of high frustration in three dimensions. Recent experimental studies of the low-temperature pr…
Anomalous Behaviour in the Magneto-Optics of a Gapped Topological Insulator
Calvin J. Tabert, J. P. Carbotte
The Dirac fermions at the surface of a topological insulator can be gapped by introducing magnetic dopants. Alternatively, in an ultra-thin slab with thickness on the order of the…
Quantum Zeno effect in the strong measurement regime of circuit quantum electrodynamics
D. H. Slichter, C. Müller, R. Vijay +3
We observe the quantum Zeno effect -- where the act of measurement slows the rate of quantum state transitions -- in a superconducting qubit using linear circuit quantum electrodyn…
Driven neutron star collapse: Type~I critical phenomena and the initial black hole mass distribution
Scott C. Noble, Matthew W. Choptuik
We study the general relativistic collapse of neutron star (NS) models in spherical symmetry. Our initially stable models are driven to collapse by the addition of one of two thing…
Recent progress on correlated electron systems with strong spin-orbit coupling
Robert Schaffer, Eric Kin-Ho Lee, Bohm-Jung Yang +1
Emergence of novel quantum ground states in correlated electron systems with strong spin-orbit coupling has been a recent subject of intensive studies. While it has been realized t…
Magnetometry of micro-magnets with electrostatically defined Hall bars
Dany Lachance-Quirion, Julien Camirand Lemyre, Laurent Bergeron +2
Micro-magnets are key components for quantum information processing with individual spins, enabling arbitrary rotations and addressability. In this work, characterization of sub-mi…
Antiferromagnetism and Hidden Order in Isoelectronic Doping of URuSi

We present muon spin rotation (SR) and susceptibility measurements on single crystals of isoelectronically doped URuTSi (T = Fe, Os) for doping levels up to 50\%…
Dense magnetized plasma associated with a fast radio burst
Kiyoshi Masui, Hsiu-Hsien Lin, Jonathan Sievers +15
Fast Radio Bursts are bright, unresolved, non-repeating, broadband, millisecond flashes, found primarily at high Galactic latitudes, with dispersion measures much larger than expec…

Yige Chen, Heung-Sik Kim, Hae-Young Kee
Numerous efforts have been devoted to reveal exotic semimetallic phases with topologically non-trivial bulk and/or surface states in materials with strong spin-orbit coupling. In p…
On the accuracy and precision of numerical waveforms: Effect of waveform extraction methodology

We present a new set of 95 numerical relativity simulations of non-precessing binary black holes (BBHs). The simulations sample comprehensively both black-hole spins up to spin mag…
Operational meaning of quantum measures of recovery
Tom Cooney, Christoph Hirche, Ciara Morgan +4
Several information measures have recently been defined which capture the notion of "recoverability." In particular, the fidelity of recovery quantifies how well one can recover a…
