If a process has this property and is also reversible, then it is isentropic.
In a twoÂ­level system with a linearlyÂ­varying energy gap, the probability to violate a theorem with thisname is given by the LandauÂ–Zener formula. That theorem with this name, which holds in the limit of a large level splitting, states that a system remains in an energy eigenstate under a slow timeÂ­dependent perturbation. During this type of process, P times V to the gamma remains constant, where gamma is an (*) "index" also known by this name. Two processes of this type connect an isothermal expansion and compression in a Carnotcycle. The only type of energy transfer that occurs in this type of process is work. If a process has this property and is also reversible, then it is isentropic. For 10 points, identify this type of thermodynamic process which occurs with no transfer of heat.
