Caltech physicists develop a groundbreaking method to improve the study of symmetry violations using entangled molecules.
In the quest to unravel the mysteries of the universe, physicists are constantly searching for new particles and forces that lie beyond the boundaries of the Standard Model. One particular puzzle that has captivated scientists is the matter-antimatter asymmetry in our universe. Caltech assistant professor of physics Nick Hutzler and his team are dedicated to understanding this phenomenon by studying symmetry violations. Now, they have made a significant breakthrough by harnessing the power of entanglement to enhance their experiments. Their findings, published in Physical Review Letters, shed light on the potential for entangled molecules to provide insights into the fundamental nature of our universe.
Entangling Molecules to Enhance Precision
Hutzler’s group has devised a novel method to entangle arrays of molecules, which act as probes for measuring symmetry violations. By connecting the molecules in this way, the experiment becomes less susceptible to background noise interference while simultaneously increasing sensitivity to the desired signal. This improvement in precision is similar to anchoring a group of rubber duckies together in a bathtub. The entangled molecules collectively respond to the desired measurement, such as the flow of a current, while being less affected by external disturbances.
Reducing Noise, Enhancing Sensitivity
The key advantage of this new approach is its ability to reduce noise while still harnessing the benefits of entanglement. Uncontrolled electric and magnetic fields from the experimental setup often hinder measurements, but the entangled molecules exhibit a reduced sensitivity to this noise. As a result, researchers can focus on studying the structure of the molecules with greater accuracy. By searching for minute tilts in electrons caused by electric fields within the molecules, the team hopes to uncover forbidden interactions that defy the predictions of the Standard Model.
Expanding the Frontiers of New Physics
The use of entangled molecules opens up unprecedented possibilities for exploring new physics. While previous methods utilizing entanglement increased sensitivity to noise, this breakthrough allows researchers to reduce noise while still benefiting from the sensitivity boost provided by entanglement. In a separate study led by Hutzler and John M. Doyle of Harvard University, the researchers demonstrated that the polyatomic molecules used in these experiments possess the unique ability to shield themselves from electromagnetic noise. With the combined advantages of entanglement and noise reduction, scientists can delve into increasingly exotic sectors of new physics, pushing the boundaries of our understanding of the universe.
Conclusion:
The groundbreaking work by Hutzler and his team at Caltech represents a significant advancement in the search for new physics. By entangling molecules and reducing background noise, they have enhanced the precision and sensitivity of their experiments, allowing for a deeper exploration of matter-antimatter asymmetry. This research holds the potential to uncover deviations from the Standard Model, shedding light on the fundamental nature of our universe. As scientists continue to push the boundaries of knowledge, the power of entangled molecules offers a promising avenue for unraveling the mysteries that lie beyond our current understanding.
