Renormalization group approach to the elastic properties of graphene bilayers
L. Delzescaux, D. Mouhanna
We investigate the effects of thermal fluctuations in graphene bilayers by means of a nonperturbative renormalization group (NPRG) approach, following the pioneering work of Mauri…

Crumpled-to-flat transition of quenched disordered membranes at two-loop order
L. Delzescaux, D. Mouhanna, M. Tissier
We investigate the effects of quenched elastic disorder on the nature of the crumpling-to-flat transition of -dimensional polymerized membranes using a two-loop computation near…

Auxiliary fields approach to shift-symmetric theories: the derivative theory and the crumpled-to-flat transition of membranes at two-loop order
L. Delzescaux, C. Duclut, D. Mouhanna +1
We introduce a technique relying on the use of auxiliary fields in order to eliminate explicit field-derivatives that plague the high orders renormalization group treatment of shif…
