Abstract

Abstract The Norman F. Ramsey Prize in Atomic, Molecular, and Optical Physics 2019 by the American Physical Society was awarded to Dr. Jun Ye. He leads the AMO Physics and Precision Measurement research group at the Joint Institute for Laboratory Astrophysics (JILA) at the University of Colorado Boulder. He was recognized for his groundbreaking contributions to precision measurements and the quantum control of atomic and molecular systems, including atomic clocks.

WALKING INTO Jun Ye's lab at the University of Colorado Boulder is a bit like walking into an electronic jungle. There are wires strung across the ceiling that hang down to the floor. Right in the middle of the room are four hefty steel tables with metal panels above them extending all the way to the ceiling. Slide one of the panels to the side and you'll see a dense mesh of vacuum chambers, mirrors, magnetic coils, and laser light bouncing around in precisely orchestrated patterns. ¶ This is one of the world's most precise and accurate clocks, and it's so accurate that you'd have to wait 40 billion years-or three times the age of the universe-for it to be off by one second. ¶ What's interesting about Ye's atomic clock, part of a joint endeavor between the University of Colorado Boulder and the National Institute of Standards and Technology (NIST), is that it is optical, not microwave like most atomic clocks. The ticking heart of the clock is the strontium atom, and it beats at a frequency of 429 terahertz, or 429 trillion ticks per second. It's the same frequency as light in the lower part of the red region of the visible spectrum, and that relatively high frequency is a pillar of the clock's incredible precision. Commonly available atomic clocks beat at frequencies in the gigahertz range, or about 10 billion ticks per second. Going from the microwave to the optical makes it possible for Ye's clock to be tens of thousands of times as precise.

Precision measurement and frequency metrology with ultracold atoms

Xibo Zhang, Jun Ye

Abstract Precision measurement and frequency metrology have pushed many scientific and technological frontiers in the field of atomic, molecular and optical physics. In this article, we provide a brief review on the recent development of optical atomic clocks, with an emphasis placed on the important inter-dependence between measurement precision and systematic effects. After presenting a general discussion on the motivation and techniques behind the development of optical lattice clocks, where the use of many atoms greatly enhances the measurement precision, we present the JILA strontium optical lattice clock as the leading system of frequency metrology with the lowest total uncertainty, and we describe other related research activities. We discuss key ingredients that have enabled the optical lattice clocks with ultracold atoms to reach the 18th digit in both precision and accuracy. Furthermore, we discuss extending the power of precision clock spectroscopy to study quantum many-body physics and to provide control for atomic quantum materials. In addition, we explore future research directions that have the potential to achieve even greater precision.

“Zeit können wir noch zehnmal genauer messen”

Seit 2018 verleiht die Amerikanische Physikalische Gesellschaft (APS) den Norman F. Ramsey‐Preis für außergewöhnliche wissenschaftliche Leistungen auf den Gebieten Atom‐, Molekül‐ und Optische Physik, mitgesponsort von der Garchinger Firma Menlo Systems, die von Theodor Hänsch gegründet wurde. 2019 erhält Jun Ye von der Universität Colorado in Boulder diesen Preis für seine grundlegenden Beiträge für Präzisionsmessungen molekularer und atomarer Systeme. Hier spricht er über die weltweit genauesten Methoden der Zeitmessung, wie diese unsere Kommunikations‐Technologien verändern und neue Perspektiven in der Quantenphysik eröffnen.
