Properties of soliton surfaces associated with integrable sigma models
We investigate certain properties of -valued
two-dimensional soliton surfaces associated with the integrable
sigma models constructed by the orthogonal rank-one
Hermitian projectors, which are defined on the two-dimensional Riemann sphere
with finite action functional. Several new properties of the projectors mapping
onto one-dimensional subspaces as well as their relations with three mutually
different immersion formulas, namely, the generalized Weierstrass, Sym-Tafel
and Fokas-Gel'fand have been discussed in detail. Explicit connections among
these three surfaces are also established by purely analytical descriptions
and, it is demonstrated that the three immersion formulas actually correspond
to the single surface parametrized by some specific conditions.Comment: 17 page
Frustration induced disordered magnetism in Ba3RuTi2O9
The title compound Ba3RuTi2O9 crystallizes with a hexagonal unit cell. It
contains layers of edge shared triangular network of Ru4+ (S=1) ions. Magnetic
susceptibility chi(T) and heat capacity data show no long range magnetic
ordering down to 1.8K. A Curie-Weiss (CW) fitting of chi(T) yields a large
antiferromagnetic CW temperature theta_CW=-166K. However, in low field, a
splitting of zero field cooled (ZFC) and field cooled (FC) chi(T) is observed
below ~30K. Our measurements suggest that Ba3RuTi2O9 is a highly frustrated
system but only a small fraction of the spins in this system undergo a
transition to a frozen magnetic state below ~30K.Comment: 5 pages, 6 figures (accepted in EPJB
‘Others’ Within the ‘Others’: An Intersectional Analysis of Gender Violence in India
In 2018, the rapes of two young girls shook India. The ruling government blatantly supported the perpetrators in both cases. It was also highlighted that if the victims were high class, high caste or belonged to the Hindu community, public and media outrage would have been different, possibly similar to what was witnessed after the December 16th 2012, Delhi Nirbhaya rape. Hence, it is valid for us to question what was different about the Nirbhaya case? Class and caste divisions form the foundation of the hierarchical nature of Indian society. Using an analysis of the Nirbhaya rape case through the lens of intersectionality, this paper explores how factors such as class, caste, religion and geography in India influence not only how a case of gender violence and the victims are perceived but is also reflected on the perception of the perpetrators and the resultant punishments meted out. Previous research establishes interesting intersections of gender and representation in the Nirbhya case (Dey and Orton, in: Gender and race matter: global perspectives on being a woman, 2016; Shandilya in Gend Hist 27(2):465–486, 2015). This paper further builds on that discourse to establish how the intersection of social segregations along with gender division and patriarchy, form a complex web of discrimination and violence in India
