Quantum Stochastic Inflation
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We formulate stochastic inflation in an open quantum system framework. The field coarse-grained in a patch of fixed physical size, and the total momentum of that patch, form a cano…
Non-Equilibrium Dynamics of the Time-Dependent Excitonic Coupling in Fluorescent Protein Dimers
Robson Christie, Cerys Murray, Youngchan Kim +1
We quantify the excitonic coupling in the homodimer of dimeric Venus fluorescent protein using a quantum-classical hybrid workflow. Employing a transition-density coupling formalis…
Cosmic Lockdown: When Decoherence Saves the Universe from Tunneling
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We investigate how quantum decoherence influences the tunneling dynamics of quantum fields in cosmological spacetimes. Specifically, we study a scalar field in an asymmetric double…
Quantum Simulation of Dynamical Transition Rates in Open Quantum Systems
Robson Christie, Kyunghyun Baek, Jeongho Bang +1
Estimating transition rates in open quantum systems is hampered by computing-resource demands that grow rapidly with system size. We present a quantum-simulation framework that ena…
The Sound of Decoherence
Robson Christie, James Trayford
We explore an unconventional bridge between quantum mechanical density matrices and sound by mapping elements of the density matrix and their phases to auditory signals, thus intro…
