Ultracold polar molecules are an exciting platform for quantum science and technology. The combination of rich internal structure of vibration and rotation, controllable long-range dipolar interactions and strong coupling to applied electric and microwave fields has inspired many applications. These include quantum simulation of strongly interacting many-body systems, the study of quantum magnetism, quantum metrology and molecular clocks, quantum computation, precision tests of fundamental physics and the exploration of ultracold chemistry.

Polyaromatic hydrocarbons (PAHs) are ubiquitous in astrochemistry and are si

Abstract: Efforts on quantum simulation and computation have lead to the realization of well-controlled quantum many-body systems. Due to practical constraints, they are inevitably open, i.e., coupled to the environment, which generally leads to decoherence but can also be used to stabilize interesting states. In the thermodynamic limit, the nonequilibrium steady states can undergo phase transitions due to the competition of unitary and driven-dissipative processes. After recalling general properties, we will discuss first simple examples.

Single atoms and molecules are the emerging frontier in engineering applications as they represent the ultimate limit of modern electronic and photonic devices. While controlling at these extremely small scales have become a reality, the understanding of energy transport, conversion, and dissipation properties of these systems is falling behind due to the lack of experimental tools.

Optics and coatings are often considered as commodity in the laser systems
across different applications. And yet, these are the main factors limiting
the efficiency, power, and lifetime of lasers and optical layouts. Moreover,
coating engineers, just like masters of dark magic, have their own language.
I will cover a variety of topics and questions, which will help to grow
awareness about the critical characteristics of optics. Answers to those
questions will also help to learn some of the language coating engineers

Abstract: Tremendous progress is being made at silicon photonic foundries around the world to improve the performance, yield and capability of photonic integrated circuits (PICs) and that is opening up new markets, including quantum computing. These results will be described with an emphasis on integrating lasers to PICs and the improvements in laser and system performance that are possible.
 

Abstract:  I will review advances to beat standard metrological limits when the quantum system is explicitly time-dependent.  In general both coherent control and adaptive strategies are required to unlock these advantages. Examples will be given in qubit systems and experiments discussed.  Recent advanced using variational methods and applications to many-body systems will also be discussed.
