WebApr 12, 2024 · A large part of statistical physics and probability theory is concerned with determining the free energy of a given Hamiltonian. In many models for disordered systems, this Hamiltonian is itself a random function. This paper focuses on the free energies of random Hamiltonians obeying rich distributional symmetries. We begin with a few … WebAny Hamiltonian matrix with a finite dimension has a discrete spectrum. So all the physical systems (or all the Hamiltonian) are gapped. Certainly, the above is not what we mean by "gapped Hamiltonian" in physics. But what does it mean for a Hamiltonian to be gapped?

The most common of these involves a linear arrangement of the potential minima in the space of all bath degrees of freedom and gives rise to a common bath that couples to the system sites.
The Hamiltonian can induce a symplectic structure on a smooth even-dimensional manifold M in several equivalent ways, the best known being the following: As a closed nondegenerate symplectic 2-form ω. According to the Darboux's theorem, in a small neighbourhood around any point on M there exist suitable local coordinates (canonical or symplectic coordinates) in which the symplectic form becomes: WebJan 23, 2024 · Hamiltonian systems (in the usual "finite-dimensional" sense of the word) play an important role in the study of certain asymptotic problems for partial …
