Stability of a high-finesse optical cavity at 493 nm in vacuum for cavity QED with Barium ions
Diptaranjan Das, Ezra Kassa, Hiroki Takahashi
We explore the stability of a high-finesse optical cavity at 493 nm in vacuum for cavity QED with Barium ions. A high-finesse Fabry-Perot cavity is built using mirrors with high-re…
Subradiance and superradiance-to-subradiance transition in dilute atomic clouds
Diptaranjan Das, B. Lemberger, D. D. Yavuz
We experimentally study subradiance in a dilute cloud of ultracold rubidium (Rb) atoms where (: atomic density, excitation wavelength) and the on…
Experimental Quantification of Entanglement Through Heat Capacity
H. Singh, T. CHakraborty, D. Das +4
A new experimental realization of heat capacity as an entanglement witness (EW) is reported. Entanglement properties of a low dimensional quantum spin system are investigated by he…
Quantification of Entanglement from Magnetic Susceptibility for a Heisenberg Spin 1/2 system
Tanmoy Chakraborty, Harkirat Singh, Diptaranjan Das +3
Temperature and magnetic field dependent magnetization and extraction of entanglement from the experimental data is reported for dichloro(thiazole)copper(II), a Heisenberg spin cha…
Comparative Study of Magnetic Behaviour in Three Classic Molecular Magnets
Tanmoy Chakraborty, Tamal K. Sen, Harkirat Singh +3
We have studied the magnetic properties of three phenalenyl based organic neutral radicals. The first one is a Heisenberg chain antiferromagnet with one unpaired spin per molecule;…
Experimental detection of quantum information sharing and their quantification in quantum spin systems
Diptaranjan Das, Tanmoy Chakraborty, Harkirat Singh +1
We study the macroscopic entanglement properties of a low dimensional quantum spin system by investigating its magnetic properties at low temperatures and high magnetic fields. The…
