# Scaling flow on covariance forms of CCR algebras

@article{Yamagami2018ScalingFO, title={Scaling flow on covariance forms of CCR algebras}, author={Shigeru Yamagami}, journal={Letters in Mathematical Physics}, year={2018}, volume={110}, pages={371-385} }

In connection with parametric rescaling of free dynamics of CCR, we introduce a flow on the set of covariance forms and investigate its thermodynamic behavior at low temperature with the conclusion that every free state approaches to a selected Fock state as a limit.

We show that the functional calculus of sesquilinear forms derived in [3] leads to a general theory of the Wigner, Yanase, Dyson-Lieb-type inequalities. In particular, we obtain the joint convexity…
