Dr Tanmoy Chakraborty, Assistant Professor of Physics, SIAS, Krea University, has co-authored a research paper titled 31P NMR Studies of the 1/3-Depleted Two-Dimensional Anisotropic Kagomé Lattice System BaCu₂(PO₄)₂(H₂O), published in Physical Review B.

About the paper: The word “Kagomé” has a Japanese origin meaning basket with eyes referring to the pattern of corner-shared triangles in a woven basket. In the research field of “strongly correlated spin systems” it is one of the canonical examples of geometrically frustrated spins. In this work, the authors have synthesized one single crystalline material where the spin network is 1/3-depleted Cu 2+ kagomé layers. The authors have used magic angle spinning (MAS) – nuclear magnetic resonance (NMR) and theoretical (DFT+U) electronic structure calculations to validify their model spin network. Their work is published in Physical Review B involving six different research groups across three different countries.

Dr Kalyan S Chakrabarti Publishes an Article in the Journal NPJ Systems Biology and Applications

Ram Kumar Research Spotlight

Dr Kalyan S Chakrabarti, Associate Dean (Students) and Associate Professor of Biological Sciences and Chemistry, SIAS, Krea University has co-authored an article titled Bifurcations in coupled amyloid-β aggregation-inflammation systems, published in the journal NPJ Systems Biology and Applications. The article was co-authored with Davood Bakhtiari (Stadtapotheke Calw Pharmacy) and Dr Nasrollah Rezaei-Ghaleh (University of Düsseldorf). 

Dr Chakrabarti extends his gratitude to Krea University for providing computational facilities and intramural funding. He also acknowledges the contributions of Krea alumni Lipi Savitha, Kathan Pandya, Meghna Rao, Yazhini LA and Gauri Velloor, as well as SIAS student Netra Krishna, who have contributed to different aspects of the project as part of their Capstone Theses at Krea University. Additionally, he thanks Dr Abuthahir Abdul Rahuman and Professor Gaurav Raina for their discussions, which significantly contributed to the project’s conception.

About the Paper

In this article, the authors investigate a simple coupled system of amyloid-beta (Ab) aggregation and inflammation relevant in Alzheimer disease (AD) and demonstrate its complex and rich dynamics ranging from overdamped kinetics to sustained oscillations in dependence of various aggregation- and neuroinflammation-related parameters. They suggest that sustained oscillations in inflammatory response to Ab aggregation and its resultant exhaustion of the immune system can lead to a transition to a more progressive phase of amyloid pathology in AD brains. Accordingly, oscillations in aggregation and/or inflammation levels can serve as potential biomarkers in early diagnosis of AD. The authors also propose that the relative ease of triggering oscillatory dynamics in coupled aggregation-neuroinflammation systems should be taken into consideration in clinical trials related to anti-AD drug development.

Dr Rama Koteswara Rao Kamineni’s Paper, Published in the Journal Physical Review B, Selected as an ‘Editor’s Suggestion’

Ram Kumar Research Spotlight

Dr Rama Koteswara Rao Kamineni, Associate Professor of Physics, SIAS, Krea University has co-authored a paper titled Vector detection of ac magnetic fields by nitrogen vacancy centers of single orientation in diamond, published in the journal Physical Review B. The paper, selected as an ‘Editor’s Suggestion’, was co-authored with Pooja Lamba (Bennett University), Akshat Rana (Bennett University), Sougata Halder (IIT Jodhpur), Dr Siddharth Dhomkar (IIT Madras) and Professor Dieter Suter (Dortmund University). 

About the paper: Nitrogen vacancy (NV) centers in diamond have useful properties for detecting both ac and dc magnetic fields with high sensitivity at nanoscale resolution. The vector detection of ac magnetic fields can be achieved by using NV centers having three different orientations. In this paper, the authors propose a method to achieve this by using NV centers of single orientation. In this method, a static magnetic field is applied perpendicular to the NV axis, leading to strong mixing of the mₛ = −1 and 1 electron spin states. As a result, all three electron spin transitions of the triplet ground state have nonzero dipole moments, with each transition coupling to a single component of the magnetic field. This can be used to measure both the strength and orientation of the applied ac field. To validate the technique, the authors perform a proof-of-principle experiment using a subset of ensemble NV centers in diamond, all having the same orientation. This method is equally applicable to single NV centers.

Dr C P Anil Kumar Publishes a Paper in the Indian Journal of Pure and Applied Mathematics (IJPA)

Ram Kumar Research Spotlight

Dr C P Anil Kumar, Assistant Professor of Mathematics, SIAS, Krea University authored a paper titled On Infinity Type Hyperplane Arrangements and Convex Positive Bijections, published in the Indian Journal of Pure and Applied Mathematics (IJPA). 

About the Publication

Consider a hyperplane arrangement, i.e., a finite collection of hyperplanes, in an n-dimensional Euclidean space. We say that an arrangement is generic if there are at least n hyperplanes and a codimension k intersection is formed by exactly k many hyperplanes.  This is an interesting arrangement – for example, for a fixed m ≥ n, a generic arrangement of m hyperplanes in an n-dimensional Euclidean space has the maximum number of regions. Two arrangements are (combinatorially) isomorphic (or equivalent) if there is an ambient linear homeomorphism which preserves incidences between strata and the polyhedral structure of each stratum. In general, it is an interesting (and difficult) problem to understand the isomorphism classes of arrangements.

In this paper, the author introduces and defines a new type of hyperplane arrangements called infinity type hyperplane arrangements.  The concept of normal systems (which is a collection of normal directions to these hyperplanes)  are used to uniquely identify such generic arrangements. The main theorem states that the equivalence of two infinity type generic hyperplane arrangements is equivalent to the isomorphism of corresponding normal systems. The author also considers the case of all generic arrangements and proves that equivalence of arrangements implies isomorphism of normal systems. Further, a counter example is provided to show that the converse need not be true.

Sayantan Datta Co-Authors a Chapter in the Book ‘Diversity, Equity and Inclusion: Creating Value Based Sustainable Organizations’

Sayantan Datta, Assistant Professor of Practice at the Centre for Writing and Pedagogy (CWP), Krea University has co-authored a book chapter titled Trials & Tribulations of LGBTQ+ People at Work as Barriers to Their Job Satisfaction: A Minority Stress Theory Perspective. This chapter, co-authored with Professor Uma Warrier, Professor at the Centre for Management Studies, Jain University, and Gouri Priya, Clinical Counselor at Workplace Options, has been published in the book Diversity, Equity and Inclusion: Creating Value Based Sustainable Organizations (Routledge, 2024). 

In their peer-reviewed book chapter, Warrier, Priya and Datta draw upon their collaborative qualitative study that used semi-structured interviews with 32 queer and transgender participants to identify unique stressors that individuals from these minority groups encounter at the workplace. The findings of the study also emphasize the need for targeted interventions that could help people with diverse genders and sexualities to manage their ‘minority stress’ and improve their job satisfaction. The authors first presented their paper in a conference earlier this year at the University of Hyderabad.
