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…
