Bonus Properties of States of Low Energy
R. Banerjee, M. Niedermaier
States of Low Energy (SLE) are exact Hadamard states defined on arbitrary Friedmann-Lemaître spacetimes. They are constructed from a fiducial state by minimizing the Hamiltonian's…

Graph rules for the linked cluster expansion of the Legendre effective action
Rudrajit Banerjee, Max Niedermaier
Graph rules for the linked cluster expansion of the Legendre effective action are derived and proven in Euclidean dimensions. A key aspect is the weight assigned t…

Critical behavior of the hopping expansion from the Functional Renormalization Group
Rudrajit Banerjee
A lattice version of the widely used Functional Renormalization Group (FRG) for the Legendre effective action is solved - in principle exactly - in terms of graph rules for the lin…
