In the quest to uncover new particles and forces in nature, physicists are exploring behaviors within atoms and molecules that defy the laws of the Standard Model of particle physics. These deviations, known as “new physics,” could hold the key to understanding the abundance of matter in our universe. Caltech assistant professor of physics Nick Hutzler and his group are focused on studying symmetry violations, which played a crucial role in the dominance of matter over antimatter in the early universe. Now, they have made a breakthrough by harnessing the power of quantum entanglement to enhance their studies.<\/p>\n
When the universe was born approximately 14 billion years ago, matter and antimatter are believed to have existed in equal amounts. However, in our present universe, matter far outweighs antimatter. To explain this asymmetry, physicists are searching for deviations in particle behaviors that could have tipped the balance in favor of matter. Hutzler’s group is dedicated to uncovering these symmetry violations through tabletop experiments.<\/p>\n
In a recent study published in Physical Review Letters, the Caltech team, led by Chi Zhang, developed a new method for entangling arrays of molecules. Entanglement is a phenomenon in quantum physics where two remote particles remain connected, allowing for shared properties and interactions. By entangling the molecules, the researchers were able to reduce the impact of background noise and enhance the sensitivity to the desired signal.<\/p>\n
To illustrate the concept, Hutzler uses the analogy of anchoring rubber duckies together in a tub. When the duckies are connected, they become less sensitive to the noise of splashing water and more responsive to other factors, such as the flow of a current. Similarly, the entangled molecules in the experiment become less sensitive to uncontrolled electric and magnetic fields, allowing for more accurate measurements of the molecules’ structure.<\/p>\n
The new method developed by Zhang and the team enables researchers to search for tiny tilts in electrons within the molecules, indicating interactions with electric fields. According to the Standard Model, such interactions are forbidden. By utilizing entanglement, the researchers can reduce noise while increasing sensitivity to these forbidden interactions. This breakthrough opens up new possibilities for exploring exotic sectors of new physics.<\/p>\n
In a separate study led by Hutzler and John M. Doyle of Harvard University, the researchers discovered that the polyatomic molecules used in these experiments possess unique abilities to shield themselves from electromagnetic noise. By tuning the sensitivity of the molecules to external fields, the researchers were able to render them largely immune to noise. This finding, combined with the advantages of entanglement, allows researchers to push the boundaries of these experiments even further.<\/p>\n
The quest for new physics and the understanding of the dominance of matter in our universe has led physicists to explore deviations from the Standard Model. Caltech researchers, led by Nick Hutzler and Chi Zhang, have made significant strides by harnessing the power of quantum entanglement to enhance their studies of symmetry violations. By entangling arrays of molecules, the researchers have reduced the impact of noise and increased sensitivity to forbidden interactions. This breakthrough opens up new avenues for probing exotic sectors of new physics and brings us one step closer to unraveling the mysteries of our universe.<\/p>\n","protected":false},"excerpt":{"rendered":"
