Wormhole geometries supported by strange quark matter and phantom-like generalized Chaplygin gas within f (Q) gravity
A crucial aspect of wormhole (WH) physics is the inclusion of exotic matter, which requires
violating the null energy condition. Here, we explore the potential for WHs to be sustained by …
