“…In the dilatonic case, the black hole boundary of the domain of existence corresponds to static dilatonic black holes [64]. For other coupling functions, which give rise to spontaneously scalarized GB black holes, the black hole boundary of the domain of existence of scalarized wormholes [59,65] consists of the corresponding spontaneously scalarized black holes [2][3][4].…”

“…Here, we consider wormholes with NUT charge in (i) EsGB theory and (ii) EsCS theory, recalling and extending previous results [2,23,24]. Since one boundary of the domain of existence of wormholes in such theories is typically given by the corresponding set of black holes, we follow closely Brihaye et al [5], who have obtained the sets of spontaneously scalarized EsGB and EsCS black holes with NUT charge.…”

“…Here a cusp singularity is encountered at some value η of the radial coordinate. Cusp singularities are a recurring feature of scalarized wormholes (see [2,23,29,30]). They form, when the determinant of the coefficients of the second order terms of the ODEs vanishes.…”

“…On the other hand, if a traversable wormhole can be obtained from a more classical or semiclassical construction, it may indicate that the original proposal of the ER = EPR conjecture may be inconsistent or that the proposal should be restricted. In order to do this, the violation of the averaged null energy condition would be required [87], which would be possible if one did not consider the expectation value of the energy-momentum tensor of the entire histories [85] (i.e., if one would consider only a specific non-perturbative process [84,[88][89][90]) or if the theory would violate causality somewhat due to modifications of gravity (e.g., [35][36][37][38][39][40][41][42][43][44][45]).…”

“…However, the presence of a phantom field is not mandatory to obtain traversable wormholes. Numerous such wormholes have been obtained in alternative theories of gravity, when the energy conditions have been violated in the gravitational sector (see, e.g., [35][36][37][38][39][40][41][42][43][44][45]). But even in GR, wormholes can be supported only by fermions [46], i.e., the constituents of ordinary matter, which is also sufficient to violate the energy conditions.…”
