2 Jan 2023 | | Abstract: | We investigate the holographic entanglement entropy (HEE) and holographic
subregion complexity (HSC) for the holographic superconductors in the Einstein
gravity and Einstein-Gauss-Bonnet gravity. For the ground state and excited
states, we observe that, in the Einstein gravity, the HSC decreases as the
temperature increases and the normal phase has a smaller HSC than the
superconducting phase, which is the opposite to the behavior of the HEE. And
for a given temperature $T$ in the superconducting phase, the higher excited
state leads to a lager value of the HEE but a smaller value of the HSC.
However, the Einstein-Gauss-Bonnet gravity has significantly different effect
on the HSC, while the HEE always increases monotonously with the increase of
the temperature and its value in the normal phase always larger than that in
the superconducting phase. The HEE and HSC provide richer physics in the phase
transition and the condensate of the scalar hair for holographic
superconductors with excited states. | | Source: | arXiv, 2301.00513 | | Services: | Forum | Review | PDF | Favorites | |
