Holographic dark energy with non-minimal derivative coupling to gravity effects

Understand

Non-minimal derivative coupling (NMDC) to gravity in flat FLRW universe is investigated in the scenario of holographic dark energy.

• Kinetic term is coupled to the Einstein tensor under potential $V = (1/2)m^2 \phi^2$.
• The free kinetic term is allowed to be canonical and phantom.
• Gravitational constant is modified with the NMDC coupling.
