A note on the Lee-Yang circle theorem
Ranjan Kumar Ghosh
A simple proof of the celebrated theorem of Lee and Yang is attempted in this short note.
Duality and even number spin-correlation functions in the two dimensional square lattice ising model
Ranjan Kumar Ghosh
The Kramers-Wannier duality is shown to hold for all the even number spin correlation functions of the two dimensional square lattice Ising model in the sense that the high tempera…
On the low temperature series expansion for the diagonal correlation functions in the two-dimensional Ising model
Ranjan Kumar Ghosh
A previously tested differential equation method for generating low temperature series expansion for diagonal spin-spin correlation functions in the d=2 Ising model is extended to…
A non-singular potential for the Dirac monopole
Ranjan Kumar Ghosh, Palash B. Pal
We propose a new vector potential for the Abelian magnetic monopole. The potential is non-singular in the entire region around the monopole. We argue how the Dirac quantization con…
Is There a Problem with Quantum Gravitation?
Ranjan Kumar Ghosh
We argue that Quantum Gravitation forces us to sum over metrics of all signatures.
Exactly Solvable Fermionic N-chain Models
Ranjan Kumar Ghosh, P. K. Mohanty, Sumathi Rao
Motivated by the problem of N coupled Hubbard chains, we investigate a generalisation of the Schulz-Shastry model containing two species of one-dimensional fermions interacting via…
