Recent years have enjoyed an overwhelming interest in quantum thermodynamics, a field of research aimed at understanding thermodynamic tasks performed in the quantum regime. Further progress, however, seems to be obstructed by the lack of experimental implementations of thermal machines in which quantum effects play a decisive role. In this work, we introduce a blueprint of quantum field machines, which - once experimentally realized - would fill this gap. We provide a detailed proposal how to… 
Quantum thermodynamically consistent local master equations
Local master equations are a widespread tool to model open quantum systems, especially in the context of many-body systems. These equations, however, are believed to lead to thermodynamic anomalies
Quantum machines powered by correlated baths
We consider thermal machines powered by locally equilibrium reservoirs that share classical or quantum correlations. The reservoirs are modeled by the so-called collisional model or repeated
Mechanisms for the emergence of Gaussian correlations
We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system undergoing
Iterative shaping of optical potentials for one-dimensional Bose-Einstein condensates

Quantum technologies are currently the object of high expectations from governments and private companies, as they hold the promise to shape safer and faster ways to exchange and treat information.
Chiral quantum state transfer in waveguide QED
Globular clusters are relics of the early universe, containing some of the oldest stars known to astronomers and providing unique insight into the evolution of the universe. Recent research has
Breaking of Huygens–Fresnel principle in inhomogeneous Tomonaga–Luttinger liquids
Tomonaga–Luttinger liquids (TLLs) can be used to effectively describe one-dimensional quantum many-body systems such as ultracold atoms, charges in nanowires, superconducting circuits, and gapless


Correlations and dynamics of tunnel-coupled one-dimensional Bose gases
We present a series of experiments performed with two ultracold one-dimensional Bose gases (rubidium atoms) in a double well potential. Employing matter-wave interference, we can measure the
Atom chips.
The next big challenge is manipulating single atoms, allowing them to have controlled collisions and coupling them to single photons in optical microcavities, which will lead to new quantum devices and ultimately to quantum information processing on a chip.

A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
