Gravitational Entanglement in Optomechanics: Distinguishing Classical and Quantum Models
Samuel Schlegel, Ankit Kumar, Tomasz Paterek +1
Observation of gravitationally induced quantum entanglement is often interpreted as a direct evidence of non-classical gravity. While the form and the degree of non-classicality ha…

A simulation study on the sub-threshold joint gravitational wave-electromagnetic wave observation on binary neutron star mergers
Yun-Fei Du, Emre Seyit Yorgancioglu, Jin-Hui Rao +4
The coalescence of binary neutron stars (BNS) is a prolific source of gravitational waves (GWs) and electromagnetic (EM) radiation, offering a dual observational window into the Un…

Constraining gravitational wave velocities using gravitational and electromagnetic wave observations of white dwarf binaries
Tian-Yong Cao, Ankit Kumar, Shu-Xu Yi
Although the general theory of relativity (GR) predicts that gravitational waves (GWs) have exactly the same propagation velocity as electromagnetic (EM) waves, many theories of gr…
