Description
Abstract:
In the coming years, several new experiments to detect gravitational waves (GWs) will come online, including KAGA and INDIGO at frequencies above 1 Hz and LISA, which is optimized for frequencies below .01 Hz. The mid-frequency band between these ranges offers many interesting scientific opportunities, including searches for GWs from the mergers of intermediate-mass black holes with masses above 1000 solar masses that may have been important in the assembly of the supermassive black holes in galactic centres, as well as GWs from first-order phase transitions in the early universe and cosmic strings. Terrestrial experiments based on cold atom interferometry could have interesting sensitivities in the mid-frequency GW band, as well as for detecting ultra-light dark matter. Finally, I present a concept for a cold atom experiment in space called AEDGE, and discuss some of its capabilities.
Brief CV:
Professor John Ellis earned his Ph.D. in theoretical particle physics in 1971 at Cambridge University. As the world-renowned particle physicist, he was awarded theMaxwell Medal and Prize (1982) and thePaul Dirac Medal and Prize (2005) by theInstitute of Physics. He is an Elected Fellow of theRoyal Society of Londonsince 1985 and of the Institute of Physics since 1991. He won the First Award in theGravity Research Foundationessay competition (1999 and 2005). Professor Ellis is currently the Clerk Maxwell Professor of Theoretical Physics atKing's College London.He is a Distinguished Visiting Fellow of TDLI and serves on the International Advisory Committee (IAC) of TDLI. He has been appointedCommander of the British Empire (CBE)since 2012. He was twice the Deputy Division Leader for the Theory Division of CERN, and served as Division Leader for 1988–1994. He was a founding member of the LEPC and the LHCC. He is the Chair of the committee to investigate Physics Opportunities for Future Proton Accelerators, and is a member of the extendedCLIC(Compact Linear Collider) Steering Committee.
