Primordial black holes and secondary gravitational waves from generalized power-law non-canonical inflation with quartic potential

Understand

Here, generation of PBHs and secondary GWs from non-canonical inflation with quartic potential have been probed.

• It is illustrated that, quartic potential in non-canonical setup with a generalized power-law Lagrangian density can source a consistent inflationary era with the latest observational data.
• Besides, we show that our model satisfies the swampland criteria.
• At the same time, defining a peaked function of inflaton field as non-canonical mass scale parameter $M(\phi)$ of the Lagrangian, gives rise to slow down the inflaton in a while.
