Ground State Properties in the Quasi-Classical Regime

  title={Ground State Properties in the Quasi-Classical Regime},
  author={Michele Correggi and Marco Falconi and Marco Olivieri},
  journal={arXiv: Mathematical Physics},
We study the ground state energy and ground states of systems coupling non-relativistic quantum particles and force-carrying Bose fields, such as radiation, in the quasi-classical approximation. The latter is very useful whenever the force-carrying field has a very large number of excitations,and thus behaves in a semiclassical way, while the non-relativistic particles, on the other hand, retain their microscopic features. We prove that the ground state energy of the fully microscopic model… 

Quasi-classical Ground States. II. Standard Model of Non-relativistic QED

. We consider a non-relativistic electron bound by an external potential and coupled to the quantized electromagnetic field in the standard model of non-relativistic QED. We compute the energy

Quasi-classical Ground States. I. Linearly Coupled Pauli-Fierz Hamiltonians

. We consider a spinless, non-relativistic particle bound by an external potential and linearly coupled to a quantized radiation field. The energy E ( u, f ) of product states of the form u ⊗ Ψ f ,

Bogoliubov Dynamics and Higher-order Corrections for the Regularized Nelson Model

We study the time evolution of the Nelson model in a mean-field limit in which N nonrelativistic bosons weakly couple (w.r.t. the particle number) to a positive or zero mass quantized scalar field.

Towards a derivation of Classical ElectroDynamics of charges and fields from QED

. The purpose of this article is twofold: • On one hand, we rigorously derive the Newton–Maxwell equation in the Coulomb gauge from first principles of quantum electrodynamics in agreement with the

Derivation of the Maxwell-Schr\"odinger Equations: A note on the infrared sector of the radiation field

We slightly extend prior results about the derivation of the Maxwell-Schrödinger equations from the bosonic Pauli-Fierz Hamiltonian. More concretely, we show that the findings from [25] about the

Quasi-Classical Spin-Boson Models

. In this short note we study Spin-Boson Models from the Quasi-Classical stand-point. In the Quasi-Classical limit, the field becomes macroscopic while the particles it interacts with, they remain

The Casimir-Polder effect for an approximate Pauli-Fierz model: the atom plus wall case

We study a system composed of a hydrogen atom interacting with an infinite conductor wall. The interaction energy decays like L ´ 3 , where L is the distance between the atom and the wall, due to the



Effective Potentials Generated by Field Interaction in the Quasi-Classical Limit

We study the quasi-classical limit of a quantum system composed of finitely many nonrelativistic particles coupled to a quantized field in Nelson-type models. We prove that, as the field becomes

The mean-field approximation and the non-linear Schrödinger functional for trapped Bose gases

We study the ground state of a trapped Bose gas, starting from the full many-body Schrodinger Hamiltonian, and derive the nonlinear Schrodinger energy functional in the limit of large particle

Magnetic Schrödinger operators as the quasi-classical limit of Pauli–Fierz-type models

We study the quasi-classical limit of the Pauli-Fierz model: the system is composed of finitely many non-relativistic charged particles interacting with a bosonic radiation field. We trace out the

Ground states in non-relativistic quantum electrodynamics

Abstract.The excited states of a charged particle interacting with the quantized electromagnetic field and an external potential all decay, but such a particle should have a true ground state – one

Ground states and spectrum of quantum electrodynamics of non-relativistic particles

A system consisting of finitely many nonrelativistic particles bound on an external potential and minimally coupled to a massless quantized radiation field without the dipole approximation is

Quasi-Classical Dynamics

We study quantum particles in interaction with a force-carrying field, in the quasi-classical limit. This limit is characterized by the field having a very large number of excitations (it is

Hamiltonian systems and semiclassical dynamics for interacting spins in QED

In this article, we consider fixed spin-1/2 particles interacting through the quantized electromagnetic field in a constant magnetic field. We give approximate evolutions of coherent states. This

We consider in this paper the problem of the existence of a ground state for a class of Hamiltonians used in physics to describe a confined quantum system (”matter”) interacting with a massless

Wigner Measures Approach to the Classical Limit of the Nelson Model: Convergence of Dynamics and Ground State Energy

We consider the classical limit of the Nelson model, a system of stable nucleons interacting with a meson field. We prove convergence of the quantum dynamics towards the evolution of the coupled
