# Twisted logarithmic modules of free field algebras

@article{Bakalov2016TwistedLM, title={Twisted logarithmic modules of free field algebras}, author={Bojko Bakalov and McKay Sullivan}, journal={arXiv: Quantum Algebra}, year={2016} }

Given a non-semisimple automorphism $\varphi$ of a vertex algebra $V$, the fields in a $\varphi$-twisted $V$-module involve the logarithm of the formal variable, and the action of the Virasoro operator $L_0$ on such module is not semisimple. We construct examples of such modules and realize them explicitly as Fock spaces when $V$ is generated by free fields. Specifically, we consider the cases of symplectic fermions (odd superbosons), free fermions, and $\beta\gamma$-system (even superfermions…
