Effective potential in curved space and cut-off regularizations
(Elsevier B.V., 2011-11-11)
We consider derivation of the effective potential for a scalar field in curved space-time within the physical regularization scheme, using two sorts of covariant cut-off regularizations. The first one is based on the local ...
Holographic renormalization flows, entanglement entropy and the sum rule
(Springer, 2016-03-07)
We calculate the two-point function of the trace of the stress tensor in holographic renormalization group flows between pairs of conformal field theories. We show that the term proportional to the momentum squared in this ...
Effective potential in curved space and cut-off regularizations
(Elsevier B.V., 2011-11-11)
We consider derivation of the effective potential for a scalar field in curved space-time within the physical regularization scheme, using two sorts of covariant cut-off regularizations. The first one is based on the local ...
Non-Fermi-liquid superconductivity: Eliashberg approach versus the renormalization group
(American Physical Society, 2017-04)
We address the problem of superconductivity for non-Fermi liquids using two commonly adopted, yet apparently distinct, methods: (1) the renormalization group (RG) and (2) Eliashberg theory. The extent to which both methods ...
Renormalization group structure for sums of variables generated by incipiently chaotic maps
(IOP Publishing, 2010-01)
We look at the limit distributions of sums of deterministic chaotic variables in unimodal maps and find a remarkable renormalization group (RG) structure associated with the operation of increment of summands and rescaling. ...

Wilson-Fisher fixed points for any dimension
(American Physical Society, 2019-12)
The critical behavior of a nonlocal scalar field theory is studied. This theory has a nonlocal quartic interaction term which involves a power-β of the Laplacian. The power-β is tuned so as to make that interaction marginal ...
