    Complex trajectories of a simple pendulum.

    , Journal of Physics A: Mathematical and Theoretical, Vol: 40, Pages: F81-F89

    The motion of a classical pendulum in a gravitational field of strength g is explored. The complex trajectories as well as the real ones are determined. If g is taken to be imaginary, the Hamiltonian that describes the pendulum becomes PT-symmetric. The classical motion for this PT-symmetric Hamiltonian is examined in detail. The complex motion of this pendulum in the presence of an external periodic forcing term is also studied.

    Numerical experiments with p F- and q D-strings: the formation of (p,q) bound states

    , Journal of Cosmology and Astroparticle Physics, Vol: 11

    We investigate the behaviour of (p, q) string networks, focusing on two aspects: (1) modelling more realistic (p, q) string networks than the ZN networks used so far, and (2) investigating the effect of long-range interactions on the evolution of the network. We model the network with no long-range interactions using two sets of fields, complex scalars coupled to gauge fields, with a potential chosen such that the two types of strings will form bound states. This way we can model junctions of three strings with different tension; in ZN models used so far in simulations all the strings have identical tensions. In order to introduce long-range interactions we also study a network in which one of the scalars forms global strings. We observe that in the absence of long-range interactions the formation of bound states has a significant influence on the evolution of the network. When long-range interactions are turned on, the bound states are short-lived and have a minimal effect on the network evolution.

    Modelling Cultural Dynamics: A Macroscopic Approach To Cultural Transmission In The Prehistoric Aegean

    In this paper we pursue a novel transdisciplinary approach to the question of cultural dynamics, focussing particularly on the transmission of cultural traits across socio-physical space. In order to think through some of the themes involved we take as a case study an inter-regional phenomenon known as �Minoanisation� (Wiener 1990; Broodbank 2004). This term describes a set of processes observed in the prehistoric Aegean (specifically the Middle and early Late Bronze Age) whereby �Minoan� cultural traits find themselves transmitted beyond the Minoan sphere, i.e. the island of Crete. That is to say, communities in regions such as the Cyclades, the Dodecanese, coastal Asia Minor and the Greek mainland adopt aspects of Cretan culture, both in the form of actual imports from Crete and also local imitations thereof. These cultural elements include pottery shapes and styles, stone vases, loomweights and wall paintings; not only new forms of material culture, but also, presumably, new cultural practices.

    Scaling solutions to 6D gauged chiral supergravity

    , New Journal of Physics, Vol: 8, Pages: 1-26, ISSN: 1367-2630

    We construct explicitly time-dependent exact solutions to the field equations of six-dimensional (6D) gauged chiral supergravity, compactified to 4D in the presence of up to two three-branes situated within the extra dimensions. The solutions we find are scaling solutions, and are plausibly attractors which represent the late-time evolution of a broad class of initial conditions. By matching their near-brane boundary conditions to physical brane properties, we argue that these solutions (together with the known maximally symmetric solutions and a new class of non-Lorentz-invariant static solutions, which we also present here) describe the bulk geometry between a pair of three-branes with non-trivial on-brane equations of state.

    Signature reversal invariance

    , Nuclear Physics B, Vol: 758, Pages: 161-184, ISSN: 0550-3213

    We consider the signature reversing transformation of the metric tensor induced by the chiral transformation of the curved space gamma matrices in spacetimes with signature , which also induces a spacetime orientation reversal. We conclude: (1) It is a symmetry only for chiral theories with , with k integer. (2) Yang–Mills theories require dimensions with T even for which even rank antisymmetric tensor field strengths and mass terms are also allowed. For example, super-Yang–Mills is ruled out. (3) Gravitational theories require dimensions with T odd, for which the symmetry is preserved by coupling to odd rank field strengths. In , for example, it is a symmetry of and type IIB supergravity but not type IIA. A cosmological term and also mass terms are forbidden but non-minimal coupling is permitted. (4) Spontaneous compactification from leads to interesting but different symmetries in lower dimensions such as , so Yang–Mills terms, Kaluza–Klein masses and a cosmological constant may then appear. As a well-known example, IIB permits .
