Frictional work and entropy production in integrable and non-integrable spin chains
Vishnu Muraleedharan Sajitha, Matthew J. Davis, L. A. Williamson
The maximum work extractable from a quantum system is achieved when the system is driven adiabatically. Frictional work then quantifies the differe…

Global Variational Quantum Circuits for Arbitrary Symmetric State Preparation
Liam J. Bond, Matthew J. Davis, JiÅà MináŠ+3
Quantum states that are symmetric under particle exchange play a crucial role in fields such as quantum metrology and quantum error correction. We use a variational circuit compose…

Quantum thermal machine regimes in the transverse-field Ising model
Vishnu Muraleedharan Sajitha, Bodhaditya Santra, Matthew J. Davis +1
We identify and interpret the possible quantum thermal machine regimes with a transverse-field Ising model as the working substance. In general, understanding the emergence of such…
