Large scale dynamical response of interacting Fermi systems
Marcello Porta, Giuseppe Scola, Harman Preet Singh
We consider the dynamics of a class of weakly interacting, gapless fermionic systems, in presence of small external perturbations slowly varying in space and in time. We consi…
Non-trivial fixed point of a fermionic theory, II. Anomalous exponent and scaling operators
Alessandro Giuliani, Vieri Mastropietro, Slava Rychkov +1
We consider the Renormalization Group (RG) fixed-point theory associated with a fermionic model in with fractional kinetic term, whose scaling dimension is fixed…
Free energy expansions for renormalized systems for colloids
Tong Xuan Nguyen, Giuseppe Scola, Dimitrios Tsagkarogiannis
We consider a binary system of small and large spheres of finite size in a continuous medium interacting via a non-negative potential. We work in the canonical ensemble and compute…
