Abstract We discover that some unstable vacua have long memory. By that we mean that even in the theories containing only massive particles, there are correllators and expectation values which grow with time. We examine the cases of instabilities caused by the constant electric fields, expanding and contracting universes and, most importantly, the global de Sitter space. In the last case the interaction leads to a remarkable UV/IR mixing and to a large back reaction. This gives reasons to believe that the cosmological constant problem could be resolved by the infrared physics.

• Infrared instability of the de Sitter space (2012, methodology): “The self-energy corrections to the Schwinger - Keldysh propagators are expressed in terms of the products of these amplitudes, for example the +/- correction to the two point function 〈φ(qτ)φ(−qτ)〉 is proportional to the integral ∫ ddk|A(q, k)|2 (see [2] for the details).”
