Finite-energy Gottesman-Kitaev-Preskill state-enhanced optical interferometry
Ashmita Roy, R. Srikanth, Deepak Pandey
We present the case of a Gottesman-Kitaev-Preskill (GKP) state-enhanced optical interferometry with detailed analysis of the phase sensitivity for both the SU(2) and SU(1,1) interf…
A fiber Fabry-Perot cavity based spectroscopic gas sensor
Carlos Saavedra, Deepak Pandey, Wolfgang Alt +2
Optical spectroscopic sensors are powerful tools for analysing gas mixtures in industrial and scientific applications. Whilst highly sensitive spectrometers tend to have a large fo…
Tunable Fiber Fabry-Perot Cavities with High Passive Stability
Carlos Saavedra, Deepak Pandey, Wolfgang Alt +2
We present three high finesse tunable monolithic fiber Fabry-Perot cavities (FFPCs) with high passive mechanical stability. The fiber mirrors are fixed inside slotted glass ferrule…
Ground-State Cooling of a Single Atom in a High-Bandwidth Cavity
Eduardo Uruñuela, Wolfgang Alt, Elvira Keiler +4
We report on vibrational ground-state cooling of a single neutral atom coupled to a high-bandwidth Fabry-Pérot cavity. The cooling process relies on degenerate Raman sideband trans…
Non-adiabatic Storage of Short Light Pulses in an Atom-Cavity System
Tobias Macha, Eduardo Uruñuela, Wolfgang Alt +4
We demonstrate the storage of ns light pulses in a single rubidium atom coupled to a fiber-based optical resonator. Our storage protocol addresses a regime beyond the conventio…
Transport properties of Valine in water at different temperatures
Deepak Pandey, Narayan Prasad Adhikari
Molecular Dynamics simulations of Valine in water and their binary mixtures ( =0.003 \& =0.997, representing the mole fraction) have been accomplished at te…
Strong Purcell effect on a neutral atom trapped in an open fiber cavity
Jose Gallego, Wolfgang Alt, Tobias Macha +3
We observe a sixfold Purcell broadening of the D line of an optically trapped atom strongly coupled to a fiber cavity. Under external illumination by a near-re…
BEC array in a Malleable Optical Trap formed in a Traveling Wave Cavity
D. S. Naik, G. Kuyumjyan, D. Pandey +2
Although quantum degenerate gases of neutral atoms have shown remarkable progress in the study of many body quantum physics, condensed matter physics, precision measurements, and q…
Time-delayed intensity-interferometry of the emission from ultracold atoms in a steady-state magneto-optical trap
Muhammed Shafi K., Deepak Pandey, Buti Suryabrahmam +2
An accurate measurement of the bunching of photons in the fluorescent emission from an ultracold ensemble of thermal 87Rb atoms in a steady-state magneto-optical trap is presented.…
Classical Light Sources with Tunable Temporal Coherence and Tailored Photon Number Distributions
Deepak Pandey, Nandan Satapathy, Buti Suryabrahmam +2
We demonstrate the generation of classical incoherent light with electronic control over its temporal characteristics and photon number distribution. The tunability of the temporal…
Optical phase noise engineering via acousto-optic interaction and its interferometric applications
Nandan Satapathy, Deepak Pandey, Sourish Banerjee +1
We exercise rapid and fine control over the phase of light by transferring digitally gen- erated phase jumps from radio frequency (rf) electrical signals onto light by means of aco…
Classical light analogue of the nonlocal Aharonov-Bohm effect
Nandan Satapathy, Deepak Pandey, Poonam Mehta +3
We demonstrate the existence of a non-local geometric phase in the intensity-intensity correlations of classical incoherent light, that is not seen in the lower order correlations.…
