Sensitivity Comparison of Two-photon vs Three-photon Rydberg Electrometry
Nikunjkumar Prajapati, Narayan Bhusal, Andrew P. Rotunno +7
We investigate the sensitivity of three-photon EIT in Rydberg atoms to radio frequency detection and compare it against conventional two-photon systems. Specifically, we model the…
Electromagnetically induced transparency in inhomogeneously broadened solid media
Haoquan Fan, Kumel H. Kagalwala, Sergey V. Polyakov +2
We study, theoretically and experimentally, electromagnetically induced transparency (EIT) in two different solid-state systems. Unlike many implementations in homogeneously broade…
Intracavity Rydberg atom electromagnetically induced transparency using a high finesse optical cavity
Jiteng Sheng, Yuanxi Chao, Santosh Kumar +3
We present an experimental study of cavity assisted Rydberg atom electromagnetically induced transparency (EIT) using a high-finesse optical cavity (). Rydberg atoms…
Rydberg-atom based radio-frequency electrometry using frequency modulation spectroscopy in room temperature vapor cells
Santosh Kumar, Haoquan Fan, Harald Kübler +2
Rydberg atom-based electrometry enables traceable electric field measurements with high sensitivity over a large frequency range, from gigahertz to terahertz. Such measurements are…
Atom-Based Sensing of Weak Radio Frequency Electric Fields Using Homodyne Readout
Santosh Kumar, Haoquan Fan, Harald Kübler +2
We utilize a homodyne detection technique to achieve a new sensitivity limit for atom-based, absolute radio-frequency electric field sensing of .…
Collective state synthesis in an optical cavity using Rydberg atom blockade
Santosh Kumar, Jiteng Sheng, Jonathon A. Sedlacek +2
We investigate the coherent manipulation of interacting Rydberg atoms placed inside a high-finesse optical cavity for the deterministic preparation of strongly coupled light-matter…
Sub-wavelength microwave electric field imaging using Rydberg atoms inside atomic vapor cells
H. Q. Fan, S. Kumar, R. Daschner +2
We have recently shown that Alkali atoms contained in a vapor cell can serve as a highly accurate standard for microwave electric field strength as well as polarization using the p…
Atom Based Vector Microwave Electrometry Using Rubidium Rydberg Atoms in a Vapor Cell
J. Sedlacek, A. Schwettmann, Harald Kübler +1
It is clearly important to pursue atomic standards for quantities like electromagnetic fields, time, length and gravity. We have recently shown, using Rydberg states, that Rb atoms…
