A Generalized Coherent State Framework for Many-Body Density of States
Deniz Coskun, R. Chitra
We develop a general framework to calculate the many-body density of states (DOS) of isolated and interacting quantum systems. Based on the generalized coherent state formalism and…

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…

A Bosonic Mean-Field Theory for Frustrated Heisenberg Antiferromagnets in Two Dimensions
R. Chitra, Sumathi Rao, Diptiman Sen
We use a recently developed bosonic mean-field theory (MFT) to study the ordered ground states of frustrated Heisenberg antiferromagnets (FHAFM) in two dimensions. We emphasize the…
