Why spinor bec is called ''spinor bec''?

[wdlang]

what does spinor means?

why do not just call it a multicomponent bec?

Ho's paper does not explain why.

The meaning of a spinor has been a topic of many discussions here. Thats why, in the past, i tried to make the summary below :

The term "spinor" in "spinor BEC" refers to a mathematical object called a spinor, which represents the intrinsic angular momentum or "spin" of a particle. In a spinor BEC, the individual particles have a non-zero spin, which gives rise to unique properties and behaviors in the system.

Calling it a "multicomponent BEC" would not accurately capture the significance of the spinor aspect. While a multicomponent BEC may have multiple components, they may not necessarily have spin, and thus would not exhibit the same properties as a spinor BEC.

As for why Ho's paper does not explicitly explain the term, it is likely assumed that readers of the paper are familiar with the concept of spinors and their importance in describing quantum systems. However, it is always important to clarify and define terminology in scientific literature to avoid confusion.
