Information transfer along the causal lightcone of a brickwork quantum circuit
Shivansh Singh, Shane Dooley
Understanding how local information propagates through many-body quantum systems is a central problem in nonequilibrium dynamics, with important implications for quantum communicat…
Parent Hamiltonians for stabilizer quantum many-body scars
Shane Dooley
Quantum many-body scars (QMBS) have attracted considerable interest due to their role in weak ergodicity breaking in many-body systems. We present a general construction that embed…
Perfect quantum state transfer through a chaotic spin chain via many-body scars
Shane Dooley, Luke Johnston, Patrick Gormley +1
Quantum many-body scars (QMBS) offer a mechanism for weak ergodicity breaking, enabling non-thermal dynamics to persist in a chaotic many-body system. While most studies of QMBS fo…
Taking the temperature of quantum many-body scars
Phillip C. Burke, Shane Dooley
A quantum many-body scar is an eigenstate of a chaotic many-body Hamiltonian that exhibits two seemingly incongruous properties: its energy eigenvalue corresponds to a high tempera…
