Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Entropy production and non-Gaussianity of fast processes at weak damping
Mario A. Ciampini, Jakob Rieser, Nikolai Kiesel +1
We present a method of estimating the rate of entropy production in underdamped dynamics by decomposing it into contributions originating in different non-equilibrium effects. Spec…
Free expansion of a charged nanoparticle via electrostatic compensation
David Steiner, Yaakov Y. Fein, Gregor Meier +5
Coherent wavepacket expansion is a key component of recent proposals aiming to create non-classical states of a levitated dielectric nanoparticle. Free evolution, i.e., releasing t…
Feedback stabilization of a nanoparticle at the intensity minimum of an optical double-well potential
VojtÄch MlynáÅ, Salambô Dago, Jakob Rieser +5
In this work, we develop and analyze adaptive feedback control strategies to stabilize and confine a nanoparticle at the unstable intensity minimum of an optical double-well potent…
Quantifying protocol efficiency: a thermodynamic figure of merit for classical and quantum state-transfer protocols
Qiongyuan Wu, Mario A. Ciampini, Mauro Paternostro +1
Manipulating quantum systems undergoing non-Gaussian dynamics in a fast and accurate manner is becoming fundamental to many quantum applications. Here, we focus on classical and qu…
Stabilizing nanoparticles in the intensity minimum: feedback levitation on an inverted potential
Salambô Dago, Jakob Rieser, Mario A. Ciampini +5
We demonstrate the stable trapping of a levitated nanoparticle on top of an inverted potential using a combination of optical readout and electrostatic control. The feedback levita…
