Spontaneous dimerization and moment formation in the Hida model of spin-1 kagomé antiferromagnet
Pratyay Ghosh, Brijesh Kumar
The Hida model, defined on honeycomb lattice, is a spin-1/2 Heisenberg model of aniferromagnetic hexagons (with nearest-neighbor interaction, ) coupled via ferromagnetic bon…

Level crossings induced by a longitudinal coupling in the transverse field Ising chain
Grégoire Vionnet, Brijesh Kumar, Frédéric Mila
We study the effect of antiferromagnetic longitudinal coupling on the one-dimensional transverse field Ising model with nearest-neighbour couplings. In the topological phase where,…

Theory of Quantum Oscillations of Magnetization in Kondo Insulators
Panch Ram, Brijesh Kumar
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. T…
