Renormalized Oscillator Hamiltonians
Let pj, q,, denote the self-adjoint operators -iajax, and multiplication by x, on L’(W), respectively. Let H,, = (l/2) xyr= r o,(pf +qj-l)whereo,>O,andletPbe a polynomial in the q’s that is bounded below. The existence and uniqueness problems are considered for H, + IF’(q) renormalized relative to its own ground state. For example, suppose that P has degree 2d and P(q) >~(qf + ... +qz)“-k for s...
متن کاملImportance of multispin couplings in renormalized Hamiltonians.
We introduce a Monte Carlo approach to the calculation of more distant renormalized interactions with higher accuracy than is possible with previous methods. We have applied our method to study the effects of multispin interactions, which turn out to be far more important than commonly assumed. Even though the individual multispin interactions usually have smaller coupling constants than two-sp...
متن کاملQuantum Models Related to Fouled Hamiltonians of the Harmonic Oscillator
We study a pair of canonoid (fouled) Hamiltonians of the harmonic oscillator which provide, at the classical level, the same equation of motion as the conventional Hamiltonian. These Hamiltonians, say K1 and K2, result to be explicitly time-dependent and can be expressed as a formal rotation of two cubic polynomial functions, H1 and H2, of the canonical variables (q, p). We investigate the role...
متن کامل9 Oscillator representations for self - adjoint Calogero Hamiltonians
In the article arXiv:0903.5277 [quant-ph], we have presented a mathematically rigorous quantum-mechanical treatment of a one-dimensional motion of a particle in the Calogero potential V (x) = αx−2. In such a way, we have described all possible s.a. operators (s.a. Hamiltonians) associated with the formal differential expression Ȟ = −dx + αx−2 for the Calogero Hamiltonian. Here, we discuss a new...
متن کاملProblems with the definition of renormalized Hamiltonians for momentum-space renormalization transformations.
For classical lattice systems with finite (Ising) spins, we show that the implementation of momentum-space renormalization at the level of Hamiltonians runs into the same type of difficulties as found for real-space transformations: Renormalized Hamiltonians are ill-defined in certain regions of the phase diagram.
