Abstract: TTbar and other solvable irrelevant deformations have received considerable attention in the past few years. In this talk, I will first explain the importance of TTbar deformation for the understanding of several fundamental issues in quantum field theories. These include the S-matrix bootstrap program and UV completeness of quantum field theories. After that, the main features of TTbar deformation will be discussed. Finally I will show how these deformations can be defined in a much broader family of integrable models such as integrable spin chains and cold atom systems. The physical properties of the deformed models will also be discussed.
