D-branes at multicritical points

open access: yesJournal of High Energy Physics, 2008
The moduli space of c=1 conformal field theories in two dimensions has a multicritical point, where a circle theory is equivalent to an orbifold theory. We analyse all the conformal branes in both descriptions of this theory, and find convincing evidence that the full brane spectrum coincides.

Electronic multicriticality in bilayer graphene

open access: yesPhysical Review B, 2012
We map out the possible ordered states in bilayer graphene at the neutrality point by extending the previous renormalization group treatment of many-body instabilities to finite temperature, trigonal warping and externally applied perpendicular electric field.

Old and New Results on Multicritical Points

open access: yesJournal of Statistical Physics, 2003
Thirty years after the Liu-Fisher paper on the {\bf bicritical} and {\bf tetracritical} points in quantum lattice gases, these multicritical points continue to appear in a variety of new physical contexts. This paper reviews some recent multicritical phase diagrams, which involve e. g. high-$T_c$ superconductivity and various magnetic phases which may (

Combinatorial rigidity of multicritical maps

open access: yes, 2011
We combine the KSS nest constructed by Kozlovski, Shen and van Strien, and the analytic method proposed by Avila, Kahn, Lyubich and Shen to prove the combinatorial rigidity of multicritical maps.

On multicritical lattice/orbifold models

open access: yesPhysics Letters B, 1990
Abstract It is shown that all multicritical lattice/orbifold models (i.e. multicritical models which may be formulated both as lattice models or as (non-trivial) orbifolds thereof) are obtained from lattice models with enhanced symmetry by twistings belonging to the Weyl group of the corresponding root lattice.
