A many-body Fredholm index for ground state spaces and Abelian anyons
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We propose a many-body index that extends Fredholm index theory to many-body systems. The index is defined for any charge-conserving system with a topologically ordered -dimensi…
Invariant measure for stochastic Schrödinger equations
Tristan Benoist, Martin Fraas, Yan Pautrat +1
Quantum trajectories are Markov processes that describe the time-evolution of a quantum system undergoing continuous indirect measurement. Mathematically, they are defined as solut…
Non-Markovian noise that cannot be dynamically decoupled by periodic spin echo pulses
Daniel Burgarth, Paolo Facchi, Martin Fraas +1
Dynamical decoupling is the leading technique to remove unwanted interactions in a vast range of quantum systems through fast rotations. But what determines the time-scale of such…
