用动量截断定义了固定总动量极化子的哈密顿量。通过证明截断哈密顿量的预解式的强收敛,在二维空间中定义了固定总动量的重整化哈密顿量。物理极化子的哈密顿量被定义为固定动量哈密顿量的直接积分。
Hamiltonians for the polaron of fixed total momentum are defined using momentum cutoffs. A renormalized Hamiltonian of fixed total momentum is defined in two space dimensions by proving the strong convergence of the resolvents of the cutoff Hamiltonians. The Hamiltonian for the physical polaron is defined as the direct integral of the fixed momentum Hamiltonians.
