EIT spectroscopy on rubidium Rydberg states

In this paper, a series of electromagnetically-induced-transparent (EIT) spectra of different Rydberg states, controlled by microwaves, in rubidium (Rb) thermal vapor are presented. The novel evolution regularity for different Rydberg states can be found by experimentally detected transmitted EIT spectra, which can reveal the primary quantum number of different Rydberg states and how to influence microwave control spectroscopy evolution regularity, and which can pave the way in order to address the challenge of selecting Rydberg states for applications in Rydberg microwave field detection. This is helpful for the development of measuring standards of the microwave field in Rydberg states.In this paper, a series of electromagnetically-induced-transparent (EIT) spectra of different Rydberg states, controlled by microwaves, in rubidium (Rb) thermal vapor are presented.

In this work, we precisely measure the transition energies between the Rydberg state n $\text{D}_{5/2}$ to the nearby Rydberg states $(\e{n}+2)\text{P}_{3/2}$, $(\e{n}-2)\text{F}_{7/2}$ for the range $41\leq \e{n}\leq46$. This was done by carrying out microwave spectroscopy via Electromagnetically Induced Transparency (EIT) in a room temperature vapor reference cell of Rubidium, which is similar to the experimental approach followed by Li et al. [Results in Physics \textbf{29}, 104728 (2021)]. This range is interesting because there is a quasi Förster resonance between the atomic pair $43\text{D}_{5/2}+43\text{D}_{5/2}$ and $45\text{P}_{3/2}+41\text{F}_{7/2}$ . We compared the obtained results with numerically calculated transition energies based on previously tabulated quantum defect numbers by various research groups using both hot and ultra-cold atomic samples. Our data are more consistent with measurements made within ultra-cold atomic systems [Phys. Rev. A \textbf{67}, 052502 (2003), Phys. Rev. A \textbf{74}, 054502 (2006)].In this work, we precisely measure the transition energies between the Rydberg state n$\text{D}_{5/2}$ to the nearby Rydberg states $(\e{n}+2)\text{P}_{3/2}$, $(\e{n}-2)\text{F}_{7/2}$ for the range $41\leq \e{n}\leq46$.

In this work, we precisely measure the transition energies between the Rydberg state n D 5 / 2 to the nearby Rydberg states ( n + 2 ) P 3 / 2 , ( n − 2 ) F 7 / 2 in 85 Rb for the range 41 ≤ n ≤ 46 . This was done by carrying out microwave spectroscopy via electromagnetically induced transparency (EIT) in a room temperature vapor reference cell of rubidium, which is similar to the experimental approach followed by Li et al., (2021). This range is interesting because there is a quasi Förster resonance between the atomic pair 43 D 5 / 2 + 43 D 5 / 2 and 45 P 3 / 2 + 41 F 7 / 2 . We compared the obtained results with numerically calculated transition energies based on previously tabulated quantum defect numbers by various research groups using both hot and ultra-cold atomic samples. Our data are more consistent with measurements made within ultra-cold atomic systems (Li et al., 2003; Han et al., 2006). • Precision Metrology. • Quantum Atomic Sensor. • Quantum Information Processing. • Quantum Computation. • Quantum Technologies.In this work, we precisely measure the transition energies between the Rydberg state n D 5 / 2 to the nearby Rydberg states ( n + 2 ) P 3 / 2 , ( n − 2 ) F 7 / 2 in 85 Rb for the range 41 ≤ n ≤ 46 .
