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…
Optimal qubit-mediated quantum heat transfer via noncommuting operators and strong coupling effects
Marlon Brenes, Jakub GarwoÅa, Dvira Segal
Heat transfer in quantum systems is a current topic of interest due to emerging quantum technologies that attempt to miniaturize engines and examine fundamental aspects of thermody…
Open quantum systems with non-commuting coupling operators: An analytic approach
Jakub GarwoÅa, Dvira Segal
We present an analytic approach to treat open quantum systems strongly coupled to multiple environments via noncommuting system operators, a prime example is a qubit concurrently c…
Suppression of decoherence dynamics by a dissipative bath at strong coupling
Jitian Chen, Jakub GarwoÅa, Dvira Segal
Control of decoherence in open quantum systems has become a topic of great interest due to the emergence of quantum technologies that depend on quantum coherent effects. In this wo…
