Ground-state Entropy of the Ising model on a Frustrated lattice
B Sriram Shastry, Bill Sutherland, Frédéric Mila +1
We report the ground-state entropy of a 2-d Ising model on the Shastry-Sutherland lattice. We also study a generalization of this model, where a constraint on the zero temperature…
Weyl's Relations, Integrable Matrix Models and Quantum Computation
B. Sriram Shastry, Emil A. Yuzbashyan, Aniket Patra
Starting from a generalization of Weyl's relations in finite dimension , we show that the Heisenberg commutation relations can be satisfied in a specific dimensional subsp…
Yang-Lee Zeros of Certain Antiferromagnetic Models
Muhammad Sedik, Junaid Majeed Bhat, Abhishek Dhar +1
We revisit the somewhat less studied problem of Yang-Lee zeros of the Ising antiferromagnet. For this purpose, we study two models, the nearest-neighbor model on a square lattice,…
Integrable matrix theory: Level statistics
Jasen A. Scaramazza, B. Sriram Shastry, Emil A. Yuzbashyan
We study level statistics in ensembles of integrable matrices linear in a real parameter . The matrix is considered integrable if it has a prescribed number $…
Integrals of motion for one-dimensional Anderson localized systems
Ranjan Modak, Subroto Mukerjee, Emil A. Yuzbashyan +1
Anderson localization is known to be inevitable in one dimension for generic disordered models. Since localization leads to Poissonian energy level statistics, we ask if localized…
Quantum integrability in systems with finite number of levels
Emil A. Yuzbashyan, B. Sriram Shastry
We consider the problem of defining quantum integrability in systems with finite number of energy levels starting from commuting matrices and construct new general classes of such…
Bloch Walls and Macroscopic String States in Bethe's solution of the Heisenberg Ferromagnetic Linear Chain
Abhishek Dhar, B Sriram Shastry
We present a calculation of the lowest excited states of the Heisenberg ferromagnet in 1-d for any wave vector. These turn out to be string solutions of Bethe's equations with a ma…
Equilibrium and dynamical properties of the ANNNI chain at the multiphase point
Abhishek Dhar, B. Sriram Shastry, Chandan Dasgupta
We study the equilibrium and dynamical properties of the ANNNI (axial next-nearest-neighbor Ising) chain at the multiphase point. An interesting property of the system is the macro…
