The basic features of the dynamics of open quantum systems, such as the dissipation of
energy, the decay of coherences, the relaxation to an equilibrium or non-equilibrium …

Decoherence of electron spins in nanoscale systems is important to quantum technologies
such as quantum information processing and magnetometry. It is also an ideal model …

Employing the trace distance as a measure for the distinguishability of quantum states, we
study the influence of initial correlations on the dynamics of open systems. We concentrate …

Exact master equations describing the decay of a two-state system into a structured reservoir
are constructed. By employing the exact solution for the model, analytical expressions are …

We consider a process of parameter estimation in a spin-j system surrounded by a quantum-
critical spin chain. Quantum Fisher information lies at the heart of the estimation task. We …

We solve the long-standing central spin problem for a general set of inhomogeneous bath
couplings and a large class of initial bath states. We compute the time evolution of the …

Heat engines usually operate by exchanging heat with thermal baths at different (positive)
temperatures. Nonthermal baths may, however, lead to a significant performance boost …

We consider the exact reduced dynamics of a two-level system coupled to a bosonic
reservoir, further obtaining the exact time-convolutionless and Nakajima-Zwanzig non …

Most quantum theorists are familiar with different ways of describing the effective quantum
dynamics of a system coupled to external degrees of freedom, such as the Born-Markov …

The uncertainty principle is known as a foundational element of quantum theory, providing a
striking lower bound to quantify our prediction for the measured result of two incompatible …
