Experimental signatures of an absorbing-state phase transition in an open driven many-body quantum system (2017)
Journal Article

Understanding and probing phase transitions in non-equilibrium systems is an ongoing challenge in physics. A particular instance are phase transitions that occur between a non-fluctuating absorbing phase, e.g., an extinct population, and one in which...

Journal Article

We present the results of two-component (disc+bar) and three-component (disc+bar+bulge) multiwavelength 2D photometric decompositions of barred galaxies in five Sloan Digital Sky Survey (SDSS) bands (ugriz). This sample of ?3500 nearby (z

Exploring ultra-fast charge transfer and vibronic coupling with N 1s RIXS maps of an aromatic molecule coupled to a semiconductor (2017)
Journal Article

We present for the first time two-dimensional resonant inelastic x-ray scattering (RIXS) maps of multilayer and monolayer biisonicotinic acid adsorbed on the rutile TiO2(110) single crystal surface. This enables the elastic channel to be followed ove...

Dynamics of large-scale electrophysiological networks: a technical review (2017)
Journal Article

For several years it has been argued that neural synchronisation is crucial for cognition. The idea that synchronised temporal patterns between different neural groups carries information above and beyond the isolated activity of these groups has ins...

Epidemic dynamics in open quantum spin systems (2017)
Journal Article

We explore the non-equilibrium evolution and stationary states of an open many-body system which displays epidemic spreading dynamics in a classical and a quantum regime. Our study is motivated by recent experiments conducted in strongly interacting... Read More about Epidemic dynamics in open quantum spin systems.

SDSS-IV MaNGA: the different quenching histories of fast and slow rotators (2017)
Journal Article

Do the theorised different formation mechanisms of fast and slow rotators produce an observable difference in their star formation histories? To study this we identify quenching slow rotators in the MaNGA sample by selecting those which lie below the...

Thermal Schwinger pair production at arbitrary coupling (2017)
Journal Article

We calculate the rate of thermal Schwinger pair production at arbitrary coupling in weak external fields. Our calculations are valid independently of many properties of the charged particles produced, in particular their spin and whether they are ele...

Symmetries and conservation laws in non-Hermitian field theories (2017)
Journal Article

Anti-Hermitian mass terms are considered, in addition to Hermitian ones, for PT-symmetric complex-scalar and fermionic field theories. In both cases, the Lagrangian can be written in a manifestly symmetric form in terms of the PT-conjugate variables,...

Seven-Tesla magnetization transfer imaging to detect multiple sclerosis white matter lesions (2017)
Journal Article

BACKGROUND AND PURPOSE: Fluid-attenuated inversion recovery (FLAIR) imaging at 3 Tesla (T) field strength is the most sensitive modality for detecting white matter lesions in multiple sclerosis. While 7T FLAIR is effective in detecting cortical lesio... Read More about Seven-Tesla magnetization transfer imaging to detect multiple sclerosis white matter lesions.

Galaxy evolution in protoclusters (2017)
Journal Article

We investigate galaxy evolution in protoclusters using a semi-analytic model applied to the Millennium Simulation, scaled to a Planck cosmology. We show that the model reproduces the observed behaviour of the star formation history (SFH) both in prot... Read More about Galaxy evolution in protoclusters.

Eigenstate thermalization hypothesis in quantum dimer models (2017)
Journal Article

We use exact diagonalization to study the eigenstate thermalization hypothesis (ETH) in the quantum dimer model on the square and triangular lattices.
