Stability of invertible, frustration-free ground states against large perturbations
Sven Bachmann, Wojciech De Roeck, Brecht Donvil +1
A gapped ground state of a quantum spin system has a natural length scale set by the gap. This length scale governs the decay of correlations. A common intuition is that this lengt…
Apparent Heating due to Imperfect Calorimetric Measurements
Brecht Donvil, Joachim Ankerhold
Performing imperfect or noisy measurements on a quantum system both impacts the measurement outcome and the state of the system after the measurement. In this paper we are concerne…
Interference of Quantum Trajectories
Brecht Donvil, Paolo Muratore-Ginanneschi
We extend quantum trajectory theory to encompass the evolution of a large class of open quantum systems interacting with an environment at {arbitrary coupling strength}. Specifical…
