Multicritical hypercubic models [PDF]
Journal of High Energy Physics, 2021 Abstract We study renormalization group multicritical fixed points in the ϵ-expansion of scalar field theories characterized by the symmetry of the (hyper)cubic point group HN. After reviewing the algebra of HN-invariant polynomials and arguing that there can be an entire family of multicritical (hyper)cubic solutions with ϕ2n ...

THE MULTICRITICAL KONTSEVICH-PENNER MODEL [PDF]
Modern Physics Letters A, 1992 We consider the Hermitian matrix model with an external field entering the quadratic term tr (ΛXΛX) and Penner-like interaction term αN( log (1+X)-X). An explicit solution in the leading order in N is presented. The critical behavior is given by the second derivative of the free energy in α which appears to be a pure logarithm, that is a feature of c ...

Journal of Marriage and Family, Volume 84, Issue 5, Page 1507-1528, October 2022., 2022 Abstract Objective This study examines thematic content and discourse surrounding multiracial socialization between Black and non‐Black multiracial families on multiracial mommy blogs. Background Mommy blogs have been recognized as a medium through which mothers challenge dominant representations of motherhood, create community with other mothers, and ...

Transformative family scholarship: Introduction to the special issue
Journal of Marriage and Family, Volume 84, Issue 5, Page 1241-1249, October 2022., 2022 Abstract This introductory essay situates this special issue within the context of antiracism and social justice for family scholars. The editors underscore the political and social context that led the National Council on Family Relations' three flagship journals—Journal of Family Theory & Review (JFTR), Family Relations (FR), and Journal of Marriage ...

Multicritical scaling in a lattice model of vesicles [PDF]
Journal of Physics A: Mathematical and Theoretical, 2020 Abstract Vesicles, or closed fluctuating membranes, have been modelled in two dimensions by self-avoiding polygons, weighted with respect to their perimeter and enclosed area, with the simplest model given by area-weighted excursions (Dyck paths).

Colossal Magnetoresistance in Manganites as a Multicritical Phenomenon [PDF]
Physical Review Letters, 2003 The colossal magnetoresistance in manganites AMnO_3 is studied from the viewpoint of multicritical phenomena. To understand the complicated interplay of various phases, we study the Ginzburg-Landau theory in terms of both the mean-field approximation and the renormalization-group analysis to compare with the observed phase diagram.

Multicritical Fermi Surface Topological Transitions [PDF]
Physical Review Letters, 2019 A wide variety of complex phases in quantum materials are driven by electron-electron interactions, which are enhanced through density of states peaks. A well known example occurs at van Hove singularities where the Fermi surface undergoes a topological transition.

New multicritical matrix models and multicritical 2d CDT
Physics Letters B, 2012 We define multicritical CDT models of 2d quantum gravity and show that they are a special case of multicritical generalized CDT models obtained from the new scaling limit, the so-called "classical" scaling limit, of matrix models. The multicritical behavior agrees with the multicritical behavior of the so-called branched polymers.

Multicritical Landau-Potts field theory [PDF]
Physical Review D, 2020 We investigate a perturbatively renormalizable $S_{q}$ invariant model with $N=q-1$ scalar field components below the upper critical dimension $d_c=\frac{10}{3}$. Our results hint at the existence of multicritical generalizations of the critical models of spanning random clusters and percolations in three dimensions.
