Predavanje Društva matematičara i fizičara pod nazivom “Gravitational waves in Jordan-Brans-Dicke theory of gravity and cavity optomechanics” održat će dr. sc Paritosh Verma s Fakulteta za fiziku Sveučilišta u Rijeci. Predavanje će se održati u srijedu, 21. listopada 2026. u prostoriji O-029 s početkom u 12:00. Predavanje će se održati u sklopu seminara Fakulteta za fiziku i u suorganizaciji Društva matematičara i fizičara.
Sažetak predavanja:
The first part of the talk comprises theoretical background for the data analysis of gravitational waves (GWs) from spinning neutron stars in Jordan-Brans-Dicke (JBD) theory. Einstein’s general theory of relativity (GR) predicts only two tensor polarization states but a generic metric theory of gravity can also possess scalar and vector polarization states. The JBD theory attempts to modify the GR by varying gravitational constant G, and it has three polarization states. In the second part of the talk, I shall discuss the quantum optics and cavity optomechanics concepts which form the foundation of experimental work at UNIRI optics lab.
