Generation of new classes of integrable quantum and statistical models
Anjan Kundu
A scheme based on a unifying q-deformed algebra and associated with a generalized Lax operator is proposed for generating integrable quantum and statistical models. As important ap…
New series of integrable vertex models through a unifying approach
Anjan Kundu
Applying a unifying Lax operator approach to statistical systems a new class of integrable vertex models based on quantum algebra is proposed, which exhibits a rich variety for gen…
Consistent refinement of Bethe strings for spin and electron models and a new non-Bethe solution
Anjan Kundu
Well known Bethe strings in spin chains, delta-electron gas, Hubbard and t-J models are shown to be imprecise, while their consisten refinement along with a new non-Bethe r-string…
Integrability and exact solution of correlated hopping multi-chain electron systems
Anjan Kundu
Exact quantum integrability is established for a class of multi-chain electron models with correlated hopping and spin models with interchain interactions, by constructing the rela…
Refinement of Bethe ansatz string and its alternative
Anjan Kundu
The well known string solution to Bethe ansatz equations is shown to be inconsistent in its widely accepted form. A valid refinement demanding higher order corrections in subsequen…
Exact solution of a many body problem with nearest and next-nearest neighbour interactions
B. Basu-Mallick, Anjan Kundu
Recently a partially solvable many-body problem with nearest and next-nearest neighbour interactions is proposed [cond-mat/9904121]. We show that by adding a suitably chosen moment…
