The chiral symplectic universality class
We report a numerical investigation of localization in the SU(2) model
without diagonal disorder. At the band center, chiral symmetry plays an
important role. Our results indicate that states at the band center are
critical. States away from the band center but not too close to the edge of the
spectrum are metallic as expected for Hamiltonians with symplectic symmetry.Comment: accepted in Proceedings of Localisation 2002 Conference, Tokyo, Japan

Universality class of replica synchronization transition of smooth coupled map lattices in the presence of quenched disorder
Synchronization of two replicas of coupled map lattices for continuous maps
is known to be in the multiplicative noise universality class. We study this
transition in presence of identical quenched disorder in coupling in both
replicas for coupled logistic and tent maps. We study one-dimensional,
two-dimensional, and globally coupled cases. We observe a clear second-order
transition with new exponents. The order parameter decays as with
for tent map and for logistic map in any dimension. The
asymptotic order parameter grows as with for the
tent map and for the logistic map. The quenched disorder in coupling
is a relevant perturbation for the replica synchronization of coupled map
lattices. The critical exponents are different from that of the multiplicative
noise universality class. We observe that the critical exponents are
independent of dimensions and super-universal in nature

Quasiparticle localization in superconductors with spin-orbit scattering
We develop a theory of quasiparticle localization in superconductors in
situations without spin rotation invariance. We discuss the existence, and
properties of superconducting phases with localized/delocalized quasiparticle
excitations in such systems in various dimensionalities. Implications for a
variety of experimental systems, and to the properties of random Ising models
in two dimensions, are briefly discussed.Comment: 10 page
Spectral Properties and Synchronization in Coupled Map Lattices
Spectral properties of Coupled Map Lattices are described. Conditions for the
stability of spatially homogeneous chaotic solutions are derived using linear
stability analysis. Global stability analysis results are also presented. The
analytical results are supplemented with numerical examples. The quadratic map
is used for the site dynamics with different coupling schemes such as global
coupling, nearest neighbor coupling, intermediate range coupling, random
coupling, small world coupling and scale free coupling.Comment: 10 pages with 15 figures (Postscript), REVTEX format. To appear in

A Study on the Association of Entrepreneurship Ecosystem with Financial Inclusion
Purpose: The purpose of this study is to examine the association of entrepreneurship ecosystem with financial inclusion, and to explore the potential ways in which the ecosystem can be leveraged to improve access to financial services for marginalized communities.
Â
Theoretical framework: The study utilizes the ecosystem approach to entrepreneurship, which emphasizes the interdependence and interplay of various stakeholders in the entrepreneurial process. The study also draws on the concept of financial inclusion, which refers to the provision of affordable and accessible financial services to all individuals and businesses.
Â
Design/methodology/approach: The study employs a mixed-methods approach, including a literature review, case studies, and surveys, to collect data from a variety of stakeholders in the entrepreneurship ecosystem.
Â
Findings: The findings suggest that the entrepreneurship ecosystem plays a critical role in promoting financial inclusion. The ecosystem can be leveraged to increase access to financial services for marginalized communities through the development of innovative financial products and services, the creation of mentorship and networking opportunities, and the promotion of policies that encourage financial inclusion.
Â
Research, practical and social implications: The study contributes to the understanding of the relationship between entrepreneurship and financial inclusion, and has implications for policymakers and practitioners seeking to promote financial inclusion through entrepreneurship. The findings can also inform the design and implementation of programs and policies aimed at promoting entrepreneurship and financial inclusion in marginalized communities.
Â
Originality/value: The study is among the first to examine the association of entrepreneurship ecosystem with financial inclusion and to explore the potential ways in which the ecosystem can be leveraged to improve access to financial services for marginalized communities
