Master Equations and Majorana Spinors
G W Gibbons
I describe how the states of a discrete automata with p sites, each of which may be off or on, can be represented as Majorana spinors associated to a spacetime with signature (p,p)…
HyperKähler Quotient Construction of BPS Monopole Moduli Spaces
G. W. Gibbons, P. Rychenkova
We use the HyperKähler quotient of flat space to obtain some monopole moduli space metrics in explicit form. Using this new description, we discuss their topology, completeness and…
Dyson Pairs and Zero-Mass Black Holes
G. W. Gibbons, D. A. Rasheed
It has been argued by Dyson in the context of QED in flat spacetime that perturbative expansions in powers of the electric charge e cannot be convergent because if e is purely imag…
The Sen conjecture for fundamental monopoles of distinct type
G W Gibbons
I exhibit a middle-dimensional square integrable harmonic form on the moduli space of distinct fundamental BPS monopoles of an arbitrary Lie group. This is in accord with Sen's S-d…
Pair Creation of Black Holes by Domain Walls
Robert Caldwell, Andrew Chamblin, Gary Gibbons
In this paper we study the production of pairs of neutral and charged black holes by domain walls, finding classical solutions and calculating their classical actions. We find that…
Tunelling with a Negative Cosmological Constant
G W Gibbons
The point of this paper is see what light new results in hyperbolic geometry may throw on gravitational entropy and whether gravitational entropy is relevant for the quantum origin…
