Journal Article
Everest, B., Hush, M., & Lesanovsky, I. (2014). Many-body out-of-equilibrium dynamics of hard-core lattice bosons with non-local loss. Physical Review B, 90(13), Article 134306. https://doi.org/10.1103/PhysRevB.90.134306

We explore the dynamics of hard-core lattice bosons in the presence of strong non-local particle loss. The evolution occurs on two distinct time-scales, first a rapid strongly correlated decay into a highly degenerate Zeno state subspace, followed by...

We investigate the influence of high-mass X-ray binaries (HMXBs) on their high-redshift environments. Using a one-dimensional radiative transfer code, we predict the ionization and temperature profiles surrounding a coeval stellar population, compose...

Relativistic Neel-Order Fields Induced by Electrical Current in Antiferromagnets (2014)
Journal Article

We predict that a lateral electrical current in antiferromagnets can induce nonequilibrium Néel-order fields, i.e., fields whose sign alternates between the spin sublattices, which can trigger ultrafast spin-axis reorientation. Based on microscopic t... Read More about Relativistic Neel-Order Fields Induced by Electrical Current in Antiferromagnets.

Why z > 1 radio-loud galaxies are commonly located in protoclusters (2014)
Journal Article
Hatch, N. A., Wylezalek, D., Kurk, J., Stern, D., De Breuck, C., Jarvis, M., …Stevens, J. (2014). Why z > 1 radio-loud galaxies are commonly located in protoclusters. Monthly Notices of the Royal Astronomical Society, 445(1), https://doi.org/10.1093/mnras/stu1725

Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in protoclusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, which preferentially resi... Read More about Why z > 1 radio-loud galaxies are commonly located in protoclusters.

Impurities as a quantum thermometer for a Bose-Einstein condensate (2014)

We introduce a primary thermometer which measures the temperature of a Bose-Einstein Condensate in the sub-nK regime. We show, using quantum Fisher information, that the precision of our technique improves the state-of-the-art in thermometry in the s...
