Integrability breaking and bound states in Google's decorated XXZ circuits
Ana Hudomal, Ryan Smith, Andrew Hallam +1
Recent quantum simulation by Google [Nature 612, 240 (2022)] has demonstrated the formation of bound states of interacting photons in a quantum-circuit version of the XXZ spin chai…
Exploring interacting chiral spin chains in terms of black hole physics
Ewan Forbes, Matthew D. Horner, Andrew Hallam +2
In this paper we explore the properties of a 1-dimensional spin chain in the presence of chiral interactions, focusing on the system's transition to distinct chiral phases for vari…
Embedding semiclassical periodic orbits into chaotic many-body Hamiltonians
Andrew Hallam, Jean-Yves Desaules, Zlatko Papić
Protecting coherent quantum dynamics from chaotic environment is key to realizations of fragile many-body phenomena and their applications in quantum technology. We present a gener…
Bridging quantum criticality via many-body scarring
Aiden Daniel, Andrew Hallam, Jean-Yves Desaules +4
Quantum dynamics in certain kinetically-constrained systems can display a strong sensitivity to the initial condition, wherein some initial states give rise to persistent quantum r…
