Renormalisation of non-differentiable potentials
J. Alexandre, N. Defenu, G. Grigolia +5
Non-differentiable potentials, such as the V-shaped (linear) potential, appear in various areas of physics. For example, the effective action for branons in the framework of the br…
Vacuum Energy and Renormalization of the Field-Independent Term
I. G. Marian, U. D. Jentschura, N. Defenu +2
Due to its construction, the nonperturbative renormalization group (RG) evolution of the constant, field-independent term (which is constant with respect to field variations but de…
Finite Temperature Off-Diagonal Long-Range Order for Interacting Bosons
Andrea Colcelli, Nicolò Defenu, Giuseppe Mussardo +1
Characterizing the scaling with the total particle number () of the largest eigenvalue of the one--body density matrix (), provides informations on the occurrence of the of…
Detecting composite orders in layered models via machine learning
W. Rzadkowski, N. Defenu, S. Chiacchiera +2
Determining the phase diagram of systems consisting of smaller subsystems 'connected' via a tunable coupling is a challenging task relevant for a variety of physical settings. A ge…
