Quantum spin dynamics in Fock space following quenches: Caustics and vortices
J. Mumford, E. Turner, D. W. L. Sprung +1
Caustics occur widely in dynamics and take on shapes classified by catastrophe theory. At finite wavelengths they produce interference patterns containing networks of vortices (pha…
Emergence of singularities from decoherence: Quantum catastrophes
Aaron Z. Goldberg, Asma Al-Qasimi, J. Mumford +1
We use a master equation to study the dynamics of two coupled macroscopic quantum systems (e.g.\ a Josephson junction made of two Bose-Einstein condensates or two spin states of an…
Catastrophes in non-equilibrium many-particle wave functions: universality and critical scaling
J Mumford, W Kirkby, D H J O'Dell
As part of the quest to uncover universal features of quantum dynamics, we study catastrophes that form in simple many-body wave functions after a quench, focusing on two-mode syst…
