Mean-field theory for self-interacting relativistic Luttinger fermions
Holger Gies, Marta Picciau
We investigate a class of quantum field theories with relativistic Luttinger fermions and local self-interaction in scalar channels. For an understanding of possible low-energy pha…

Self-organized criticality in a relativistic Yukawa theory with Luttinger fermions
Holger Gies, Marta Picciau
We propose and investigate a Yukawa model featuring a dynamical scalar field coupled to relativistic Luttinger fermions. Using the functional renormalization group (RG) as well as…

Quantum field theories of relativistic Luttinger fermions
Holger Gies, Philip Heinzel, Johannes Laufkötter +1
We propose relativistic Luttinger fermions as a new ingredient for the construction of fundamental quantum field theories. We construct the corresponding Clifford algebra and the s…
