Magnetisation plateaux of the quantum pyrochlore Heisenberg antiferromagnet
Santanu Pal, Siddhartha Lal
We predict magnetisation plateaux ground states for Heisenberg antiferromagnets on pyrochlore lattices by formulating arguments based on gauge and spin-parity transformatio…
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…
Orbital and spin ordering physics of the MnO spinel
Santanu Pal, Siddhartha Lal
Motivated by recent experiments, we present a comprehensive theoretical study of the geometrically frustrated strongly correlated magnetic insulator MnO spinel oxide based…
