Highly excited Rydberg atoms in a room-temperature vapor cell are promising for developing a radio-frequency (RF) electric field (E-field) sensor and relevant measurement standards with high accuracy and sensitivity. The all-optical sensing approach is based on electromagnetically-induced transparency and Autler-Townes splitting induced by the RF E-field. Systematic investigation of m... https://www.roneverhart.com/1915-Old-Taylor-Bourbon-Bottled-1933-Prohibition-Bottling-Quart-low-fill/
