Low-Lying Electronic Excitations and Nonlinear Optic Properties of Polymers via Symmetrized Density Matrix Renormalization Group Method
S. Ramasesha, Swapan K. Pati, H. R. Krishnamurthy +2
A symmetrized Density Matrix Renormalization Group procedure together with the correction vector approach is shown to be highly accurate for obtaining dynamic linear and third orde…
Multi-configurational Symmetrized Projector Quantum Monte Carlo Studies of excited states of the Hubbard model
Bhargavi Srinivasan, S. Ramasesha, H. R. Krishnamurthy
We develop a novel multi-configurational Symmetrized Projector Quantum Monte Carlo (MSPQMC) method to calculate excited state properties of Hubbard models. We compare the MSPQMC re…
DMRG Studies of the Spin-Half Heisenberg System with Dimerization and Frustration
R. Chitra, Swapan K. Pati, H. R. Krishnamurthy +2
Using the density matrix renormalization group technique, we study the ground state phase diagram and other low-energy properties of an isotropic antiferromagnetic spin-half chain…
