Physicists Identify Optimal Crystal Site for Ultra-Accurate Nuclear Clock
Physicists have pinpointed an ideal location within a crystal for housing thorium atoms to create an ultra-accurate nuclear clock. Current atomic clocks, while highly precise, require extensive laboratory setups to prevent interference. Scientists are now focusing on the atomic nucleus, specifically how energy flips a single neutron between quantum states, to achieve even greater precision. Thorsten Schumm, a physicist at the Vienna University of Technology, suggests this approach could make clocks up to 10 times more precise and allow the atom itself to shield against external interference. The research, published in Science, details how Schumm and his team mapped four possible sites for a thorium atom within a crystal, identifying one that is nearly perfect for developing the most precise clock to date. This breakthrough is significant because, unlike most atoms that would require a gamma-ray laser (which is not yet feasible), the isotope thorium 229 can be triggered with an ultraviolet laser due to its ...
