We present the mathematical model for TPBS parameters via Fourier Grid Hamiltonian method after second quantization on a K-G lattice is done with Bosonic operators. This study is realistic to understand quantum localization by nonlinearity that is essential for many small-structured nano-devices. An eigen-spectrum is shown that indicates two-phonon QB state separated at upper segment of energy from a single-phonon continuum. Hence, the objective of this paper is to explore whether the switching is easier at a particular point of nonlinearity by quantum calculations hitherto not done on lithium tantalite.
