Topological Entanglement Entropy, Ground State Degeneracy and Holography
Andrei Parnachev, Napat Poovuttikul
Topological entanglement entropy, a measure of the long-ranged entanglement, is related to the degeneracy of the ground state on a higher genus surface. The exact relation depends…
Momentum dissipation and effective theories of coherent and incoherent transport
Richard A. Davison, Blaise Goutéraux
We study heat transport in two systems without momentum conservation: a hydrodynamic system, and a holographic system with spatially dependent, massless scalar fields. When momentu…
Gravitational Wave Bursts from Cosmic Superstring Reconnections
Mark G. Jackson, Xavier Siemens
We compute the gravitational waveform produced by cosmic superstring reconnections. This is done by first constructing the superstring reconnection trajectory, which closely resemb…
Consistent Decoupling of Heavy Scalars and Moduli in N=1 Supergravity
Ana Achucarro, Sjoerd Hardeman, Kepa Sousa
We consider the conditions for integrating out heavy chiral fields and moduli in N=1 supergravity, subject to two explicit requirements. First, the expectation values of the heavy…
Solar System Constraints on Gauss-Bonnet Dark Energy
Stephen C. Davis
Quadratic curvature Gauss-Bonnet gravity may be the solution to the dark energy problem, but a large coupling strength is required. This can lead to conflict with laboratory and pl…
Coupling Hybrid Inflation to Moduli
Ph. Brax, C. van de Bruck, A. C. Davis +1
Hybrid inflation can be realised in low-energy effective string theory, as described using supergravity. We find that the coupling of moduli to F-term hybrid inflation in supergrav…
