Human decision making is modified by emotional state. Rodents exhibit similar biases during interpretation of ambiguous cues that can be altered by affective state manipulations. In this study, theâ€¦ (More)

In the generalized Legendre transform construction the KÃ¤hler potential is related to a particular function. Here, the form of this function appropriate to the k-monopole metric is calculated fromâ€¦ (More)

The construction of new hyperkÃ¤hler manifolds by taking the infinite monopole mass limit of certain BPS monopole moduli spaces is considered. The one-parameter family of hyperkÃ¤hler manifolds due toâ€¦ (More)

Spiking neuron models can accurately predict the response of neurons to somatically injected currents if the model parameters are carefully tuned. Predicting the response of in-vivo neuronsâ€¦ (More)

We discuss the similarities between BPS monopoles and Skyrmions, and point to an underlying connection in terms of rational maps between Riemann spheres. This involves the introduction of a newâ€¦ (More)

Using a numerical implementation of the ADHMN construction, we compute the fields and energy densities of a charge three monopole with tetrahedral symmetry and a charge four monopole with octahedralâ€¦ (More)

We discuss the explicit formulation of the transcendental constraints defining spectral curves of SU(2) BPS monopoles in the twistor approach of Hitchin, following Ercolani and Sinha. We obtain anâ€¦ (More)

By imposing certain combined inversion and rotation symmetries on the rational maps for SU(2) BPS monopoles we construct geodesics in the monopole moduli space. In the moduli space approximationâ€¦ (More)

Certain spontaneously broken gauge theories contain massless magnetic monopoles. These are realized classically as clouds of non-Abelian fields surrounding one or more massive monopoles. In order toâ€¦ (More)

It is shown that there exists a charge five monopole with octahedral symmetry and a charge seven monopole with icosahedral symmetry. A numerical implementation of the ADHMN construction is used toâ€¦ (More)
