Single atom energy-conversion device with a quantum load
Noah Van Horne, Dahyun Yum, Tarun Dutta +4
This work reports the functioning of a single atom energy-conversion device, operating either as a quantum engine or a refrigerator, coupled to a quantum load. The "working fluid"…
High resolution spectroscopy on Te_2: new lines for reference
T. Dutta, M. Mukherjee
Ro-vibrational spectra of different electronic states of molecules are often used as absolute wavelength or frequency standards. These standards are also used to mitigate any slow…
A single atom noise probe operating beyond the Heisenberg limit
Tarun Dutta, Manas Mukherjee
According to the Heisenberg uncertainty principle, the energy or frequency uncertainty of a measurement can be at the best inversely proportional to the observation time (). The…
Absolute Te reference for barium ion at nm
T. Dutta, D. De Munshi, M. Mukherjee
Precision atomic spectroscopy is presently the work horse in quantum information technology, metrology, trace analysis and even for fundamental tests in physics. Stable lasers are…
