Detecting a gravitational wave background from inflation with null energy condition violation: prospects for Taiji
Abstract The null energy condition (NEC) is a fundamental principle in general relativity, and its violation could leave discernible signatures in gravitational waves (GWs). A violation of the NEC during the primordial era would imprint a blue-tilted spectrum on the stochastic gravitational wave bac...
