Mission: Experimentally create, manipulate and enhance coherence of quantum systems at the mesoscopic and macroscopic level. We are measuring both superconducting Josephson circuits and atomic ensembles. In the superconducting circuits, with proper engineering of parameters and materials, macroscopic physical quantities such as magnetic flux (related to a superconducting phase difference) behave quantum mechanically. The result is a controllable quantum system with energy levels and coherence. We also implement macroscopic quantum coherence via slow and stored light in atomic ensembles. We use Rubidium vapor and optical frequency lasers to excite and probe the coherence.

Quantum molecular dynamics constitutes the thrust of my research. The goal is to gain insight into realistic elementary chemical encounters. This requires the development and application of a quantum description to molecular processes. In particular the emphasis is on time-dependent approaches which can follow naturally the stream of events.

My main active research is in two fields: one is the foundations of physics, with special interest in statistical mechanics and in the explanation of the time directedness of processes, in the framework of both classical mechanics and quantum mechanics. Most of my publications are in this field, including the forthcoming book (with Meir Hemmo) The Road to Maxwell's Demon (Cambridge University Press), which offers a new conceptual foundation for statistical mechanics. he other - and closely related - field of active research is the meaning of the concept of probability, both in general and as it is used in classical and quantum physics. My publications are mostly on probaility in physics, and The Road to Maxwell's Demon offers a physically objective account of probability in physics.

Research interests: miniature quantum sensors (atomic-clocks, optical magnetometers, E-field sensors), time and frequency, miniature frequency-combs (micro-combs), and the interplay between photonics and atomic-physics. We study interactions among diverse ‘flavors’ of photons and atoms in order to (a) develop novel types of miniature quantum-sensors, and (b) understand light-matter interactions of light and atoms occurring at minuscule dimensions.

With the rise of quantum technologies and the ability to control single atoms, ions and molecules, thermodynamics faces new challenges:

  • What new thermodynamic effects can be observed in the quantum microscopic realm?
  • Can quantum heat machines drastically outperform classical heat machines?
  • Are there additional scale-dependent thermodynamic laws that become important only in small coherent systems?
  • What are the possibilities entailed in microscopic thermal control protocols?
  • How will the next generation of microscopic heat machines look like?
