Hierarchical separation of relaxation timescales from spectral localization bounds
Alex Stewart-Bozzo, Jakub GarwoÅa, Brett Min +1
We investigate the dissipative dynamics of multilevel quantum systems strongly coupled either to a lossy cavity mode or directly to a bosonic environment. By deriving spectral loca…
Compact cavity-dressed Hamiltonian framework at arbitrarily strong light-matter coupling
Jakub GarwoÅa, Dvira Segal
We present a non-perturbative Hamiltonian mapping method for quantum systems strongly coupled to a quantized field mode (cavity), yielding compact closed-form representations of hy…
Quantum Transport in Disordered Spin Networks: Emergent Timescales and Competing Pathways
Roi Nevo, Brett Min, Maggie Lawrence +2
Quantum transport in disordered systems poses intriguing fundamental questions about the interplay of disorder, interactions, and decoherence, with important implications for nanos…
Design Principles for Enhanced Quantum Transport with Site-Dependent Noise
Maggie Lawrence, Elise Wang, Dvira Segal
Environmental noise can enhance transport, an effect known as environmental noise-assisted quantum transport. Most theoretical studies focus on optimizing system parameters under s…
Impossibility of Refrigeration and Engine Operation in Minimal Qubit Repeated-Interaction Models
Gabrielle Barsky-Giles, Alessandro Prositto, Matthew Gerry +1
We investigate the operation of a qubit as a quantum thermal device within the repeated interaction framework, allowing for strong system-bath coupling and finite interaction times…
Discovery of energy landscapes towards optimized quantum transport: Environmental effects and long-range tunneling
Maggie Lawrence, Matthew Pocrnic, Erin Fung +3
Carrier transport in quantum networks is governed by a variety of factors, including network dimensionality and connectivity, on-site energies, couplings between sites and whether…
