Finite-Element Lattice Hamiltonian Matrix Elements: Anharmonic Oscillators
Abstract. The fimte-element approach to lattice field theory is both highly accurate (relative errors ~ 1/N 2, where N is the number of lattice points) and exactly unitary (in the sense that canonical commutation relations are exactly preserved at the lattice sites). In this Letter, we construct matrix elements for the time evolution operator for the anharmonic oscillator, for which the continu...

The finite-element approach to lattice field theory is both highly accurate (relative errors ∼ 1/N2, where N is the number of lattice points) and exactly unitary (in the sense that canonical commutation relations are exactly preserved at the lattice sites). In this paper we construct matrix elements for the time evolution operator for the anharmonic oscillator, for which the continuum Hamiltoni...
متن کاملNon-Hermitian matrix description of the PT −symmetric anharmonic oscillators
The PT −symmetric differential Schrödinger equation Hψ = Eψ with the operator H = H(x) = p + a x + i β x + c x + i δ x ≡ H∗(−x) on L2(−∞,∞) is studied. At a > 0 it is re-arranged as a linear algebraic diagonalization. With rigorous proof, our non-variational construction of bound states offers an infinite-dimensional analogue to the recent finite-dimensional quasi-exact solution available at th...
متن کاملLattice dynamical finite-element method
A lattice dynamical finite-element method (LDFEM) is proposed for multiscale analysis of stressed complex crystals. Interatomic potential is embedded into the constitutive relation within the hyperelasticity framework, and two energy-based lattice instability criteria, the K criterion and the soft phonon criterion, are incorporated into LDFEM for capturing stress-driven instabilities in a perfe...
متن کاملFinite-element Time Evolution Operator for the Anharmonic Oscillator
The finite-element approach to lattice field theory is both highly accurate (relative errors ∼ 1/N2, where N is the number of lattice points) and exactly unitary (in the sense that canonical commutation relations are exactly preserved at the lattice sites). In this talk I construct matrix elements for dynamical variables and for the time evolution operator for the anharmonic oscillator, for whi...
