The JILA Physics Frontiers Center (PFC), an NSF-funded science center within JILA (a world-leading physics research institute), has recently been awarded a $25 million grant after a re-competition process.

This science center brings together 20 researchers across JILA to collaborate to realize precise measurements and cutting-edge manipulations to harness increasingly complex quantum systems. Since its establishment in 2006, the JILA PFC’s dedication to advancing quantum research and educating the next generation of scientists has helped it to stand out as the heart of JILA’s excellence.

Our paper reporting squeezing below the standard quantum limit in a programmable atom array has been published in nature! Congratulations to the team! Exciting to co-publish with the Browaeys/Yao and Roos/Rey teams too!

In a recent Science paper, researchers led by JILA and NIST Fellow Jun Ye, along with collaborators JILA and NIST Fellow David Nesbitt, scientists from the University of Nevada, Reno, and Harvard University, observed novel ergodicity-breaking in C60, a highly symmetric molecule composed of 60 carbon atoms arranged on the vertices of a “soccer ball” pattern (with 20 hexagon faces and 12 pentagon faces). Their results revealed ergodicity breaking in the rotations of C60. Remarkably, they found that this ergodicity breaking occurs without symmetry breaking and can even turn on and off as the molecule spins faster and faster. Understanding ergodicity breaking can help scientists design better-optimized materials for energy and heat transfer.

Around 150 promising inventions are generated annually within the University of Colorado Boulder. To support these inventions, the Venture Partners at ���Ҵ�ý�ƽ������ organization established the Embark Deep Tech Startup Creator, an accelerator program for start-up companies coming out of ���Ҵ�ý�ƽ������. This year, Venture Partners at ���Ҵ�ý�ƽ������ announced the Embark Entrepreneurs in Residence cohort. This cohort pairs entrepreneurs with promising inventions.

In the case of JILA, entrepreneur Eva Yao will lead FLARI in bringing to market a breathalyzer capable of detecting molecules in breath or air samples invented by Jun Ye for fast detection of diseases and contaminants.

It is with heavy hearts that the JILA and NIST communities mourn the loss of renowned physicist Lewis Branscomb, who passed away on May 31, 2023, leaving behind an indelible legacy in the world of science and a profound impact on JILA. Branscomb, a brilliant mind and a cherished member of JILA will forever be remembered for his groundbreaking contributions to the field of physics and his unwavering commitment to advancing scientific knowledge. His dedication to founding JILA and serving as its first Fellow Chair will remain forever in JILA’s collective memory. His insatiable curiosity and intellectual prowess paved the way for a remarkable career that spanned over six decades.

Some of the biggest questions about our universe may be solved by scientists using its tiniest particles. Since the 1960s, physicists have been looking at particle interactions to understand an observed imbalance of matter and antimatter in the universe. Much of the work has focused on interactions that violate charge and parity (CP) symmetry. This symmetry refers to a lack of change in our universe if all particles’ charges and orientations were inverted. “This charge and parity symmetry is the symmetry that high-energy physicists say needs to be violated to result in this imbalance between matter and antimatter,” explained JILA research associate Luke Caldwell. To try to find evidence of this violation of CP symmetry, JILA and NIST Fellows Jun Ye and Eric Cornell, and their teams, including Caldwell, collaborated to measure the electron electric dipole moment (eEDM), which is often used as a proxy measure for the CP symmetry violation. The eEDM is an asymmetric distortion of the electron’s charge distribution along the axis of its spin. To try to measure this distortion, the researchers used a complex setup of lasers and a novel ion trap. Their results, published in Science as the cover story and Physical Review A, leveraged a longer experiment time to improve the precision measurement by a factor of 2.4, setting new records.

The JILA and NIST communities are recently saddened by the passing of physicist James “Jim” E. Faller. Faller was a visionary whose scientific contributions have contributed to our understanding of the universe. Faller’s work as a JILA Fellow spanned over 50 years (since 1972), and he remained actively engaged in the scientific research process, serving as NIST QPD Division Chief for a time. With heavy hearts, we bid farewell to a brilliant mind, a passionate explorer, and a respected member of the scientific community.

Renowned scientist, JILA Fellow, and University of Colorado Boulder professor Margaret Murnane has been granted an honorary doctorate from the prestigious University of Salamanca, recognizing her outstanding contributions to the field of ultrafast laser science. As a trailblazer in her field, Murnane's groundbreaking research has revolutionized our understanding of light and opened up new avenues for scientific discovery and technological innovation. This esteemed recognition from one of the oldest universities in the world serves as a testament to Murnane's remarkable achievements and lasting impact on the scientific community.

Two-dimensional materials, like graphene and 2D semiconductors, are an area of physics that has been growing tremendously in the last decade. According to JILA graduate student Ben Whetten, “That’s because they exhibit new spin and electronic physical phenomena and have much promise to build new miniaturized photonic or semiconductor nanoscale devices.” Researchers like Whetten, and his advisor, JILA Fellow, and University of Colorado Boulder professor Markus Raschke, develop methods to image these materials, giving a better understanding of their inner workings. In a new paper in NanoLetters, Raschke, and his team extended their ultrafast microscope to see nanometer-sized imperfection(s) within a 2D semiconductor sample that created some surprising nonlinear optical effects.

A new approach recently described in Physical Review Letters explores a new way to generate squeezing that is exponentially faster than previous experiments and generates a new flavor of entanglement: two-mode squeezing—a type of entanglement that is thought to be used for improving the best atomic clocks and for sensing how gravity changes the flow of time. This promising new approach was developed by a collaboration of JILA and NIST Fellows Ana Maria Rey and James K. Thompson, and their team members, along with Bhuvanesh Sundar, a former postdoctoral researcher at JILA now at Rigetti Computing, and former JILA research associate Dr. Robert Lewis-Swan, now an Assistant Professor at the University of Oklahoma.
