Process-tensor approach to full counting statistics of charge transport in quantum many-body circuits
Hari Kumar Yadalam, Mark T. Mitchison
We introduce a numerical tensor-network method to compute the statistics of the charge transferred across an interface partitioning an interacting one-dimensional many-body lattice…
Autonomous oscillations in quantum electromechanics: tensor network treatment
Mahasweta Pandit, Sheikh Parvez Mandal, Mark T. Mitchison +1
Transport-induced self-sustained oscillations in electromechanical systems convert a static electrochemical bias into robust, autonomous oscillatory motion in the absence of any ex…
Current fluctuations in nonequilibrium open quantum systems beyond weak coupling: a reaction coordinate approach
Khalak Mahadeviya, Saulo V. Moreira, Sheikh Parvez Mandal +3
We investigate current fluctuations in open quantum systems beyond the weak-coupling and Markovian regimes, focusing on a coherently driven qubit strongly coupled to a structured b…
Diagnosing chaos with projected ensembles of process tensors
Peter O'Donovan, Neil Dowling, Kavan Modi +1
The process tensor provides a general representation of a quantum system evolving under repeated interventions and is fundamental for numerical simulations of local many-body dynam…
Quantum feedback control with a transformer neural network architecture
Pranav Vaidhyanathan, Florian Marquardt, Mark T. Mitchison +1
Attention-based neural networks such as transformers have revolutionized various fields such as natural language processing, genomics, and vision. Here, we demonstrate the use of t…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
