A Tensor Network Framework for Lindbladian Spectra and Steady States
Philipp Westhoff, Mattia Moroder, Ulrich Schollwöck +1
Quantum systems coupled to (non-)Markovian environments attract increasing attention due to their peculiar physical properties. Exciting prospects such as unconventional non-equili…
Accelerating qubit reset through the Mpemba effect
Théo Lejeune, Miha PapiÄ, John Goold +3
Passive qubit reset is a key primitive for quantum information processing, whereby qubits are initialized by allowing them to relax to their ground state through natural dissipatio…
Digitally Optimized Initializations for Fast Thermodynamic Computing
Mattia Moroder, Felix C. Binder, John Goold
Thermodynamic computing harnesses the relaxation dynamics of physical systems to perform matrix operations. A key limitation of such approaches is the often long thermalization tim…
Fast and direct preparation of a genuine lattice BEC via the quantum Mpemba effect
Philipp Westhoff, Sebastian Paeckel, Mattia Moroder
We demonstrate that dissipative state preparation protocols in many-body systems can be substantially accelerated via the quantum Mpemba effect. Our approach exploits weak symmetri…
Ultrafast electronic coherence from slow phonons
Mattia Moroder, Sebastian Paeckel, Matteo Mitrano +1
Light offers a route to engineer new phases of matter far from equilibrium, including transient states suggestive of superconducting, charge-ordered, and excitonic ordering behavio…
A resource theoretical unification of Mpemba effects: classical and quantum
Alessandro Summer, Mattia Moroder, Laetitia P. Bettmann +3
The Mpemba effect originally referred to the observation that, under certain thermalizing dynamics, initially hotter samples can cool faster than colder ones. This effect has since…
