About this document
Ground State Wavefunctions in Many-Body Physics by Aman-Sharma is a document available to read on EtoBox.
The document discusses a novel approach in many-body physics where the ground state wavefunction is used to derive the Hamiltonian, rather than the traditional perturbative method. It introduces the Majumdar-Ghosh model, which describes a one-dimensional chain of spin-1/2 particles that form singlet pairs, leading to a unique ground state with no classical analog. The text also explores the implications of this model, including the existence of soliton-like defects and the concept of off-diagonal long-range
