Statefinder and Om Diagnostics for Interacting New Holographic Dark Energy Model and Generalized Second Law of Thermodynamics

摘要

In this work, we have considered that the flat FRW universe is filled withthe mixture of dark matter and the new holographic dark energy. If there is aninteraction, we have investigated the natures of deceleration parameter,statefinder and $Om$ diagnostics. We have examined the validity of the firstand generalized second laws of thermodynamics under these interactions on theevent as well as apparent horizon. It has been observed that the first law isviolated on the event horizon. However, the generalized second law is validthroughout the evolution of the universe enveloped by the apparent horizon.When the event horizon is considered as the enveloping horizon, the generalizedsecond law is found to break down excepting at late stage of the universe.
