The magnetocaloric effect dictates that temperature can be changed by varying the magnetic field under a condition described by this adjective.
Lieb and Yngvason provided a definition of this type of process by using an ordering relation and relating this type of process to the raising or lowering of a weight; that definition builds on one by Caratheodory, which defined this kind of transformation in terms of accessibility. A theorem of this name states that no transition will occur at a Landau-Zener velocity of zero and defines the namesake kind of transition to be from an eigenstate of the initial Hamiltonian to a corresponding eigenstate in the final. The magnetocaloric effect dictates that temperature can be changed by varying the magnetic field under a condition described by this adjective. Both the quantum number and entropy bear a property named for this adjective because they stay constant under slow change under a namesake "invariance theorem." The ration of heat capacity at constant pressure to the heat capacity at constant volume is known as this kind of index, and this term describes two processes that accompany isothermic processes in the Carnot cycle. For 10 points, identify this term referring to a process that occurs without heat transfer.
