Quantum simulation of spin-boson models with structured bath
Nature CommunicationsThe spin-boson model, involving spins interacting with a bath of quantum harmonic oscillators, is a widely used representation of open quantum systems that describe many dissipative processes in physical, chemical and biological systems.

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2
Advanced Materials, EarlyView.Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Exceptional points for parameter estimation in open quantum systems: analysis of the Bloch equations
New Journal of Physics, 2015 We suggest to employ the dissipative nature of open quantum systems for the purpose of parameter estimation: the dynamics of open quantum systems is typically described by a quantum dynamical semigroup generator ${\mathcal{L}}.$ The eigenvalues of ...

Andreev levels as a quantum dissipative environment [PDF]
, 2017 We argue that at subgap energies quantum behavior of superconducting weak links can be exactly accounted for by an effective Hamiltonian for a Josephson particle in a quantum dissipative environment formed by Andreev levels.
