When a player is eliminated from a multiplayer game (by losing all life, drawing from an empty library, conceding, or any other loss condition), that player leaves the game. As a direct consequence, all objects that player owns are removed from the game as well, including all permanents they control on the battlefield (CR 800.4a).
This is an immediate state-based action effect tied to the player leaving. It is not a spell or ability — the permanents simply cease to exist on the battlefield. Tokens owned by the eliminated player also disappear, since tokens are owned by the player who created them (CR 111.2).
Note the distinction between ownership and control: if an opponent had temporarily gained control of one of your permanents (via a spell like Confiscate), that permanent still leaves the battlefield when you are eliminated, because you still own it (CR 800.4a). Conversely, if you control a permanent owned by another player who is still in the game, that permanent stays (control simply reverts to its owner per CR 800.4c).
Example: Alice is eliminated in a four-player Commander game. She had a Llanowar Elves and an Island on the battlefield, and Bob had used Bribery to put Alice's Blightsteel Colossus onto the battlefield under his control. All three permanents leave: the Elves and Island because Alice owns them and they were under her control, and the Blightsteel Colossus because Alice still owns it even though Bob controlled it.
Any spells or abilities owned by the leaving player that are still on the stack are also removed (CR 800.4a), so surviving players cannot benefit from resolving them.
