Universal Growth of Krylov Complexity Across a Quantum Phase Transition
András Grabarits, Adolfo del Campo
We study the statistical properties of the spread complexity in the Krylov space of quantum systems driven across a quantum phase transition. Using the diabatic Magnus expansion, w…
Quantum Transition Rates in Arbitrary Physical Processes
Adolfo del Campo, András Grabarits, Dmitrii Makarov +1
We introduce a framework for computing time-dependent quantum transition rates (QTRs) that describe the pace of evolution of a quantum state from a given subspace to a target subsp…
Universal Defect Statistics in Counterdiabatic Quantum Critical Dynamics
András Grabarits, Adolfo del Campo
Counterdiabatic driving (CD) provides a framework for suppressing excitations in nonadiabatic processes. Exact CD protocols require nonlocal control fields, and CD approximations w…
