On Quantum Solitons in the Sawtooth Lattice
Diptiman Sen, B. Sriram Shastry, R. E. Walstedt +1
We study the sawtooth lattice of a coupled spin Heisenberg system, a variant of the railroad trestle lattice. The ground state of this system is two-fold degenerate with peri…

Large- limit of a Hubbard model in a magnetic field: chiral spin interactions and paramagnetism
Diptiman Sen, R. Chitra
We consider the large- limit of the one-band Hubbard model at half-filling on a non-bipartite two-dimensional lattice. An external magnetic field can induce a three-spin chiral…
