All physical systems are to some extent open and interacting with their environment. This insight, basic as it may seem, gives rise to the necessity of protecting quantum systems from decoherence in quantum technologies and is at the heart of the emergence of classical properties in quantum physics. The precise decoherence mechanisms, however, are often unknown for a given system. In this work, we make use of an opto-mechanical resonator to obtain key information about spectral densities of its… 

Non-Markovianity of quantum Brownian motion

We study quantum non-Markovian dynamics of the Caldeira-Leggett model, a prototypical model for quantum Brownian motion describing a harmonic oscillator linearly coupled to a reservoir of harmonic

Non-Markovian quantum Brownian motion in one dimension in electric fields

Quantum Brownian motion is the random motion of quantum particles suspended in a field (or an effective field) resulting from their collision with fast-moving modes in the field. It provides us with

Quantum Langevin equations for optomechanical systems

We provide a fully quantum description of a mechanical oscillator in the presence of thermal environmental noise by means of a quantum Langevin formulation based on quantum stochastic calculus. The

Effective Dynamics of Open Systems in Non-Equilibrium Statistical Mechanics

This dissertation investigates effective dynamics of models for open systems, of classical and quantum nature, arising in non-equilibrium statistical mechanics. The evolution of the system's position

Response Functions as Quantifiers of Non-Markovianity.

It is found that a classical Brownian particle coupled to an Ohmic bath can already exhibit non-Markovian behavior, a phenomenon related to the initial state preparation procedure.

Optimal nonequilibrium thermometry in Markovian environments

What is the minimum time required to take a temperature? In this paper, we solve this question for a large class of processes where temperature is inferred by measuring a probe (the thermometer)

Dynamical heat engines with non-Markovian reservoirs

We discuss whether, and under which conditions, it is possible to realize a heat engine simply by dynamically modulating the couplings between the quantum working medium and thermal reservoirs. For

Macroscopic entanglement in optomechanical system induced by non-Markovian environment.

The treatment of the non-Markovian quantum state diffusion (NMQSD) method paves a way to exactly solve a large category of optomechanical systems without the linearization of the Hamiltonian and shows the entanglement sudden death and revival significantly depend on the strength of the memory effect.



Path integral approach to quantum Brownian motion

Decoherence and dissipation of a quantum harmonic oscillator coupled to two-level systems

We derive and analyze the Born-Markov master equation for a quantum harmonic oscillator interacting with a bath of independent two-level systems. This hitherto virtually unexplored model plays a

Dynamics and thermodynamics of linear quantum open systems.

It is shown that the reduced density matrix of the network always obeys a local master equation with a simple analytical solution, and the third law imposes constraints on the low frequency behavior of the environmental spectral densities.

Decoherence, einselection, and the quantum origins of the classical

as quantum engineering. In the past two decades it has become increasingly clear that many (perhaps all) of the symptoms of classicality can be induced in quantum systems by their environments. Thus

Assessing non-Markovian quantum dynamics.

From a snapshot of a quantum evolution, it can be decided whether or not a channel is consistent with a time (in)dependent Markovian evolution, for which a computable measure of "Markovianity" is introduced.


Knowledge of the dynamical behavior of correlations with no classical counterpart, like entanglement, nonlocal correlations and quantum discord, in open quantum systems is of primary interest because

Preparation and detection of a mechanical resonator near the ground state of motion

This work reports the cooling of the motion of a radio-frequency nanomechanical resonator by parametric coupling to a driven, microwave-frequency superconducting resonator, and expects the mechanical resonator to be found with probability 0.21 in the quantum ground state of motion.

Entanglement and non-markovianity of quantum evolutions.

Two different measures of non-markovianity are introduced that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts when complete tomographic knowledge about the evolution is available and when no information whatsoever is available.

Entanglement of mechanical oscillators coupled to a nonequilibrium environment

Recent experiments aim at cooling nanomechanical resonators to the ground state by coupling them to nonequilibrium environments in order to observe quantum effects such as entanglement. This raises
