Platinum Jubilee (1948-2023) Raman Research Institute

 The Raman Research Institute (RRI) ls a premier research instilution in India, pursuing cutting-edb'e fundamental research in select frontier areas of Physics under oontempora.ry research lhemes. Founded by Indian

Science Nobel LaweateSir CV Raman in 1948.the lnstitutewas established

on a plot of land gifted by the then Maharaja of Mysore, Krishnaraja Wodeyar TV. RArnan served as 1he lnsritu1c·s Dircc101 carrying on his personal research until hisdemise in1970.

In 1971, RRI became lhe fl.1-sl autonomous institution to befunded by the then newlyformed DepartmentofScienceandTechnology,Government of India. The Institute has, since then. carried forward the legacy of its rounder1.1nd ernOOrked on.severnl rcsel:lrch aelivi1iesofn91ional importance.

(1)  The prediction and discovery of Dlscotlc Liquid Crystals. In 1993, Fuji films recognized this discovery as a solution to the problem of Wide Viewing screens. Today, the Oiscotic Liquid Crystals are used in most commercial LCD (Liquid C1ysrnl Oisplny) screen$ as \\ry films 10 provide wide angle viewing

(2) The predictionor the precise rorm of the ·chirp" signalsemerging rrom the merger of blackholesand che"ring down'"slgnnl at theend of thls event. Both these were validoted by the laser Interferometer Gravitational w11vc Obscrva1ory (UGO) in Scp1cmber 2015, ,11hich, for 1he f\1"$l 1ime, confirmed gravitational waves rrom a coalescing black hole bin:uy

For instance. the Institute plans to leverage from the substantial fundamental research knowledge oulput.. produced by RRI cluster of Quantum Laboratories, in developing Quantum-Enabled technologies aligning wtlh the Ni-ltional Mission on Qu.a1uum Technologies and Appllcmlons. RRJ envisions to further strengthen its collaborations with the Indian Space Research Organiincion (JSRO), par1icularly ill che Arens of Qua mum Communication,X·Ray and Radio Astronomy.
