A note on a boundary sine-Gordon model at the free-Fermion point
Rajan Murgan
We investigate the free-Fermion point of a boundary sine-Gordon model with nondiagonal boundary interactions for the ground state using auxiliary functions, obtained from T-Q equat…
The solution of an open XXZ chain with arbitrary spin revisited
Rajan Murgan, Christopher Silverthorn
The Bethe ansatz solutions for an open XXZ spin chain with arbitrary spin with N sites and nondiagonal boundary terms are revisited. The anisotropy parameter, for cases considered…
Generalized T-Q relations and the open spin-s XXZ chain with nondiagonal boundary terms
Rashad Baiyasi, Rajan Murgan
We consider the open spin-s XXZ quantum spin chain with nondiagonal boundary terms. By exploiting certain functional relations at roots of unity, we derive a generalized form of T-…
Jordan and Jordan Higher All-derivable Points of Some Algebras
Jiankui Li, Zhidong Pan, Qihua Shen
In this paper, we characterize Jordan derivable mappings in terms of Peirce decomposition and determine Jordan all-derivable points for some general bimodules. Then we generalize t…
A note on the IR limit of the NLIEs of boundary supersymmetric sine-Gordon model
Rajan Murgan
We consider the infrared (IR) limit of the nonlinear integral equations (NLIEs) for the boundary supersymmetric sine-Gordon (BSSG) model, previously obtained from the NLIEs for the…
Rigid rings and Makar-Limanov techniques
Anthony J. Crachiola, Stefan Maubach
A ring is rigid if there is no nonzero locally nilpotent derivation on it. In terms of algebraic geometry, a rigid coordinate ring corresponds to an algebraic affine variety which…
