Quantum many-body systems involving bosonic modes or gauge fields have infinite-
dimensional local Hilbert spaces which must be truncated to perform simulations of real-time …

Simulation of quantum systems is expected to be one of the most important applications of
quantum computing, with much of the theoretical work so far having focused on fermionic …

Chain-mapping techniques in combination with the time-dependent density matrix
renormalization group are a powerful tool for the simulation of open-system quantum …

The speed limit of information propagation is one of the most fundamental features in non-
equilibrium physics. The region of information propagation by finite-time dynamics is …

We establish a theoretical method which goes beyond the weak-coupling and Markovian
approximations while remaining intuitive, using a quantum master equation in a larger …

We explore excitonic energy transfer dynamics in a molecular dimer system coupled to both
structured and unstructured oscillator environments. By extending the reaction coordinate …

The propagation of information in nonrelativistic quantum systems obeys a speed limit
known as a Lieb-Robinson bound. We derive a new Lieb-Robinson bound for systems with …

A method for the systematic construction of few-body damped harmonic oscillator networks
accurately reproducing the effect of general bosonic environments in open quantum systems …

We exploit the properties of chain mapping transformations of bosonic environments to
identify a finite collection of modes able to capture the characteristic features, or fingerprint …

Determining the vibrational structure of a molecule is central to fundamental applications in
several areas, from atmospheric science to catalysis, fuel combustion modeling, biochemical …
