Rigid fields containing $\mathbb{C}$
Also, is the extension you talked about rigid as a (abstract) field or as a $\mathbb{C}$-algebra? |

Rigid fields containing $\mathbb{C}$
In the comments to the answer to the linked question, they said the methods applied so far cannot avoid a jump in cardinality. |

Rigid fields containing $\mathbb{C}$
Ok you are right, Unique should mean as a field. I don't know about a reference that there is no field of cardinality $2^{\aleph_0}$ which contains $\mathbb{C}$ and which has trivial automorphism group (over $\mathbb{Q}$). |

Thank you; Maybe "unique" should mean as a $\mathbb{C}$-field. |

Automorphisms of $\mathbb{C}$ and meromorphic functions
Yes, all constants of $\mathbb{C}$ are in. You can take it $L=(+,\cdot, 0,1) \cup\mathbb{C}$. |

You cannot use complex conjugation, since it already implicitly defines $\mathbb{R}$. |
