    Weak Minimal Area in Entanglement Entropy by Shesansu Sekhar Pal, Shubhalaxmi Rath

    Published 2015-01-01
    “…Moreover, demanding the weak minimality condition on the entanglement entropy functional with the higher derivative term puts a constraint on the Gauss-Bonnet coupling; that is, there should be an upper bound on the value of the coupling, λa<(d-3)/4(d-1).…”
