Dynamical quantum collapse and an experimental test
Tanmay Vachaspati
The quantum measurement problem may have a resolution in de Broglie-Bohm theory in which measurements lead to dynamical wavefunction collapse. We study the collapse in a simple set…
Particle emission and gravitational radiation from cosmic strings: observational constraints
P. Auclair, D. A. Steer, T. Vachaspati
We account for particle emission and gravitational radiation from cosmic string loops to determine their effect on the loop distribution and observational signatures of strings. Th…
Rolling with quantum fields
Mainak Mukhopadhyay, Tanmay Vachaspati
We study the dynamics of a classical scalar field that rolls down a linear potential as it interacts bi-quadratically with a quantum field. We explicitly solve the dynamical proble…
Monopole-antimonopole: interaction, scattering and creation
Ayush Saurabh, Tanmay Vachaspati
The interaction of a magnetic monopole-antimonopole pair depends on their separation as well as on a second "twist" degree of freedom. This novel interaction leads to a non-trivial…
Quantum Evaporation of Classical Breathers
Jan Olle, Oriol Pujolas, Tanmay Vachaspati +1
We apply the recently discovered classical-quantum correspondence (CQC) to study the quantum evaporation of breathers in an extended sine-Gordon model. We present numerical results…
Decay of Cosmic String Loops Due to Particle Radiation
Daiju Matsunami, Levon Pogosian, Ayush Saurabh +1
Constraints on the tension and the abundance of cosmic strings depend crucially on the rate at which they decay into particles and gravitational radiation. We study the decay of co…
