B-mode polarization induced by gravitational waves from kinks on infinite cosmic strings

We investigate the effect of the stochastic gravitational wave (GW) background produced by kinks on infinite cosmic strings, whose spectrum was derived in our previous work, on the B-mode power spectrum of the cosmic microwave background (CMB) [...]

Notes on properties of holographic strange metals

We investigate properties of holographic strange metals in p+2-dimensions, generalizing the analysis performed in arXiv:0912.1061. The bulk spacetime is p+2-dimensional Lifshitz black hole, while the role of charge carriers is played by probe [...]



Localizing the energy and momentum of linear gravity

A framework is developed which quantifies the local exchange of energy and momentum between matter and the linearised gravitational field. We derive the unique gravitational energy-momentum tensor consistent with this description, and find that this [...]

Phase transitions in a gas of anyons

We continue our numerical Monte Carlo simulation of a gas of closed loops on a 3 dimensional lattice, however now in the presence of a topological term added to the action corresponding to the total linking number between the loops. We compute the [...]

Fermionic current densities induced by magnetic flux in a conical space with a circular boundary

We investigate the vacuum expectation value of the fermionic current induced by a magnetic flux in a (2+1)-dimensional conical spacetime in the presence of a circular boundary. On the boundary the fermionic field obeys MIT bag boundary condition. For [...]



Axigluons cannot explain the observed top quark forward backward asymmetry

We study an SU(3)2 axigluon model introduced by Frampton, Shu, and Wang to explain the recent Fermilab Tevatron observation of a significant positive enhancement in the top quark forward-backward asymmetry relative to standard model predictions. [...]

Black holes in a box: Towards the numerical evolution of black holes in AdS space

The evolution of black holes in "confining boxes" is interesting for a number of reasons, particularly because it mimics the global structure of Anti-de Sitter geometries. These are non-globally hyperbolic space-times and the Cauchy problem may only be well defined if the initial data is [...]

13C NMR as a general tool for the assignment of absolute configuration

13C NMR chemical shifts of appropriate diastereomeric derivatives allow the unambiguous assignment of the absolute configuration of a wide variety of chiral [...]

Hybrid cyclic peptide-thiourea cryptands for anion recognition

Hybrid cyclic peptide-thiourea cryptands were synthesised in good yield and bind acetate anions strongly and selectively in competitive [...]

Cellular binding of nanoparticles in the presence of serum proteins

Two-colour fluorescence microscopy probing the cellular binding of cationic nanoparticles in the presence of serum proteins revealed that the nanoparticles associate with serum proteins in solution and bind to the cell surface as a single anionic [...]
