plasmasolid
Plasmasolid is a term used in speculative or niche discussions to describe a regime in which condensed solid matter coexists with or is immersed in a plasma, such that solid-like structural order persists while a portion of the material is ionized and interacts with the surrounding plasma. It is not a widely standardized phase and is sometimes used to refer to either a solid material embedded in a plasma or to a transitional region at a solid–plasma interface.
Contexts in which the idea arises include dusty plasmas, warm dense matter, and plasma-surface interactions. In
Possible characteristics of a plasmasolid include transport and mechanical properties intermediate between those of a solid
Formation and observation are challenging, typically requiring extreme conditions or rapid transitions. Experimental approaches rely on
