Local density of states correlations in the Lévy-Rosenzweig-Porter random matrix ensemble
SciPost PhysicsWe present an analytical calculation of the local density of states correlation function $ \beta(\omega) $ in the Lévy-Rosenzweig-Porter random matrix ensemble at energy scales larger than the level spacing but smaller than the bandwidth.

The Beta-Gompertz Distribution
Revista Colombiana de Estadística, 2014 In this paper, we introduce a new four-parameter generalized version of the Gompertz model which is called Beta-Gompertz (BG) distribution. It includes some well-known lifetime distributions such as Beta-exponential and generalized Gompertz distributions

Beta-functions for a SU(2) Matrix Model in 2 + epsilon Dimensions
, 2005 To investigate the non-perturbative, electric sector of a deconfined gauge theory at nonzero temperature, we consider a SU(2) matrix model. We compute beta-functions to one loop order for the simplest extension of the O(4) nonlinear sigma model, which involves three coupling constants.

Two $$\beta $$ β -ensemble realization of $$\beta $$ β -deformed WLZZ models
European Physical Journal C: Particles and FieldsWe consider a two $$\beta $$ β -ensemble realization of the series of $$\beta $$ β -deformed WLZZ matrix models. We demonstrate that such a realization involves $$\beta $$ β -deformed Harish-Chandra–Itzykson–Zuber integrals, one of them providing a ...

, 2016 We study the new physics contributions to neutrinoless double beta decay ($0\nu\beta \beta$) half-life and lepton flavour violation (LFV) amplitude within the framework of the minimal left-right symmetric model (MLRSM).

A random matrix decimation procedure relating $\beta = 2/(r+1)$ to $\beta = 2(r+1)$
, 2007 Classical random matrix ensembles with orthogonal symmetry have the property that the joint distribution of every second eigenvalue is equal to that of a classical random matrix ensemble with symplectic symmetry. These results are shown to be the case $r=

On Some Generalizations of the Vandermonde Matrix and Their Relations with the Euler Beta-Function [PDF]
gmj, 1994 Abstract A multiple Vandermonde matrix which, besides the powers of variables, also contains their derivatives is introduced and an explicit expression of its determinant is obtained. For the case of arbitrary real powers, when the variables are positive, it is proved that such generalized multiple Vandermonde matrix is positive definite

Continuum limit in matrix models for quantum gravity from the Functional Renormalization Group
, 2013 We consider the double-scaling limit in matrix models for two-dimensional quantum gravity, and establish the nonperturbative functional Renormalization Group as a novel technique to compute the corresponding interacting fixed point of the Renormalization

Getting Information on |Ue3|2 from Neutrinoless Double Beta Decay
Advances in High Energy Physics, 2007 We consider the possibility to gain information on the lepton mixing matrix element |Ue3| from an improved experimental limit on the effective neutrino mass governing neutrinoless double beta decay.
