Correlated spin liquids in the quantum kagome antiferromagnet at finite field: a renormalisation group analysis
Santanu Pal, Anirban Mukherjee, Siddhartha Lal
We analyse the antiferromagnetic spin- XXZ model on the kagome lattice at finite external magnetic field with the help of a nonperturbative zero-temperature renormalization gr…
Non-perturbative approach to quantum liquid ground states on geometrically frustrated Heisenberg antiferromagnets
Santanu Pal, Anirban Mukherjee, Siddhartha Lal
We have formulated a twist operator argument for the geometrically frustrated quantum spin systems on the kagome and triangular lattices, thereby extending the application of the L…
Scaling theory for Mott-Hubbard transitions
Anirban Mukherjee, Siddhartha Lal
We present a renormalization group (RG) phase diagram for the electronic Hubbard model in two dimensions on the square lattice at, and away from, half filling. The RG proced…
Classical Electrodynamics in a Unified Theory
Partha Ghose, Anirban Mukherjee
Some consequences of a fully classical unified theory of gravity and electromagnetism are worked out for the electromagnetic sector such as the occurrence of classical light beams…
