Abstract
A new, generalized definition of squeezed states is given. The author abstracts from the quantum oscillator or the vacuum state, where this concept is usually defined, and defines it with respect to any probability measure, classical or quantum. A classical case occurs, e. g., in generalized information thermodynamics of the author with two thermal temperatures: first-order T1 and second-order T2. The reference variance in this case is that of the Boltzmann-Gibbs state with one temperature T1 = T.
