Can a Spin Liquid State Persist as the Ground State in the Presence of Competing Interactions and Disorder?
Sumanta Mukherjee
In this report, we have shown that, in an otherwise geometrically frustrated lattice, the underlying interactions compete to stabilize different magnetic phases. In conjunction wit…
A unified equation for saturation magnetization and spin transport in weakly disordered ferromagnets
Sumanta Mukherjee
In this report, a unified description of the loss of saturation magnetization in the presence of a distribution of finite-size effects is provided for weakly disordered spin-1/2 fe…
Magnetic Behavior of Ferro-, Antiferro-, and Ferrimagnetic Systems in the Griffiths Phase: A Theoretical Study
Sumanta Mukherjee
In this report, we provide a theoretical framework for the magnetic behavior of the Griffiths phase, which, along with three-dimensional spin-1/2 Ising ferromagnetic systems, can b…
Percolation in a three-dimensional non-symmetric multi-color loop model
Soumya Kanti Ganguly, Sumanta Mukherjee, Chandan Dasgupta
We conducted Monte Carlo simulations to analyze the percolation transition of a non-symmetric loop model on a regular three-dimensional lattice. We calculated the critical exponent…
Thermodynamics of multi-colored loop models in three dimensions
Soumya Kanti Ganguly, Sumanta Mukherjee, Chandan Dasgupta
We study order-disorder transitions in three-dimensional \textsl{multi-colored} loop models using Monte Carlo simulations. We show that the nature of the transition is intimately r…
