Superconductivity in CoO 2 layers and the resonating valence bond mean-field theory of the triangular lattice t − J model
Brijesh Kumar,B. Sriram Shastry +1 more
TL;DR: In this paper, the resonating valence bond mean-field theory applied to the triangular lattice was used to analyze the superconductivity of two-dimensional (2D) CoO layers.
Journal ArticleDOI
Curcumin "Drug" Stabilized in Oxidovanadium(IV)-BODIPY Conjugates for Mitochondria-Targeted Photocytotoxicity.
Utso Bhattacharyya,Brijesh Kumar,Aditya Garai,Arnab Bhattacharyya,Arun Kumar,Samya Banerjee,Paturu Kondaiah,Akhil R. Chakravarty +7 more
TL;DR: Ternary oxidovanadium(IV) complexes of curcumin (Hcur), dipicolylamine (dpa) base, and its derivatives having pendant noniodinated and di-iodinated boron-dipyrromethene (BODIPY) moiety and their chloride salts were prepared, characterized, and studied for anticancer activity.
Journal ArticleDOI
Intertwined nematic orders in a frustrated ferromagnet
Yasir Iqbal,Pratyay Ghosh,Rajesh Narayanan,Rajesh Narayanan,Brijesh Kumar,Johannes Reuther,Johannes Reuther,Ronny Thomale +7 more
TL;DR: In this paper, the authors investigated the quantum phases of the frustrated spin on the square lattice with ferromagnetic and antiferromagnetic interactions and found an intermediate paramagnetic phase located between classically ordered spin phases and incommensurate spiral phases.
Journal ArticleDOI
Quantum spin models with exact dimer ground states
TL;DR: Inspired by the exact solution of the Majumdar-Ghosh model, a family of one-dimensional, translationally invariant spin Hamiltonians is constructed in this paper, where the exchange coupling is antiferromagnetic, and decreases linearly with the separation between the spins.
Journal ArticleDOI
Theory of quantum oscillations of magnetization in Kondo insulators
P. Ram,Brijesh Kumar +1 more
TL;DR: In this article, the Kondo lattice model of spin-1/2 local moments coupled to the conduction electrons at half filling is studied for its orbital response to magnetic field on bipartite lattices.
