Caustics in the sine-Gordon model from quenches in coupled 1D Bose gases
Aman Agarwal, Manas Kulkarni, D. H. J. O'Dell
Caustics are singularities that occur naturally in optical, hydrodynamic and quantum waves, giving rise to high amplitude patterns that can be described using catastrophe theory. I…
Scaling at the OTOC Wavefront: free versus chaotic models
Jonathon Riddell, Wyatt Kirkby, D. H. J. O'Dell +1
Out of time ordered correlators (OTOCs) are useful tools for investigating foundational questions such as thermalization in closed quantum systems because they can potentially dist…
False signals of chaos from quantum probes
W. Kirkby, D. H. J. O'Dell, J. Mumford
We demonstrate that two-time correlation functions, which are generalizations of out-of-time-ordered correlators (OTOCs), can show 'false-flags' of chaos by exhibiting behaviour pr…
Fall-to-the-centre as a symmetry breaking transition
Sriram Sundaram, C. P. Burgess, D. H. J. O'Dell
The attractive inverse square potential arises in a number of physical problems such as a dipole interacting with a charged wire, the Efimov effect, the Calgero-Sutherland model, n…
Exactly solvable model behind Bose-Hubbard dimers, Ince-Gauss beams, and aberrated optical cavities
R. Gutiérrez-Cuevas, D. H. J. O'Dell, M. R. Dennis +1
By studying the effects of quadratic anisotropy and quartic perturbations on the two-dimensional harmonic oscillator, one arrives at a simple model termed here the Ince oscillator,…
Caustics in quantum many-body dynamics
W. Kirkby, Y. Yee, K. Shi +1
We describe a new class of nonequilibrium quantum many-body phenomena in the form of networks of caustics that dominate the many-body wavefunction in the semiclassical regime follo…
