[كتاب][B] Spectral theory of block operator matrices and applications

C Tretter - 2008‏ - books.google.com
This book presents a wide panorama of methods to investigate the spectral properties of
block operator matrices. Particular emphasis is placed on classes of block operator matrices …

Counterexample to the Laptev–Safronov conjecture

S Bögli, JC Cuenin - Communications in Mathematical Physics, 2023‏ - Springer
Abstract Laptev and Safronov (Commun Math Phys 292 (1): 29–54, 2009) conjectured an
inequality between the magnitude of eigenvalues of a non-self-adjoint Schrödinger operator …

Ground states in the spin boson model

D Hasler, I Herbst - Annales Henri Poincaré, 2011‏ - Springer
We prove that the Hamiltonian of the model describing a spin which is linearly coupled to a
field of relativistic and massless bosons, also known as the spin-boson model, admits a …

Bose particles in a box II. A convergent expansion of the ground state of the Bogoliubov Hamiltonian in the mean field limiting regime

A Pizzo - arxiv preprint arxiv:1511.07025, 2015‏ - arxiv.org
In this paper we consider an interacting Bose gas at zero temperature, in a finite box and in
the mean field limiting regime. The N gas particles interact through a pair potential of …

On spectral renormalization group

J Fröhlich, M Griesemer, IM Sigal - Reviews in Mathematical …, 2009‏ - World Scientific
The operator-theoretic renormalization group (RG) methods are powerful analytic tools to
explore spectral properties of field-theoretical models such as quantum electrodynamics …

Analytic perturbation theory and renormalization analysis of matter coupled to quantized radiation

M Griesemer, DG Hasler - Annales Henri Poincaré, 2009‏ - Springer
For a large class of quantum mechanical models of matter and radiation we develop an
analytic perturbation theory for non-degenerate ground states. This theory is applicable, for …

Spectral analysis of a model for quantum friction

S De Bievre, J Faupin, B Schubnel - Reviews in Mathematical …, 2017‏ - World Scientific
An otherwise free classical particle moving through an extended spatially homogeneous
medium with which it may exchange energy and momentum will undergo a frictional drag …

Ground state and resonances in the standard model of the non-relativistic QED

IM Sigal - Journal of Statistical Physics, 2009‏ - Springer
We prove existence of a ground state and resonances in the standard model of the non-
relativistic quantum electro-dynamics (QED). To this end we introduce a new canonical …

Bose particles in a box I. A convergent expansion of the ground state of a three-modes Bogoliubov Hamiltonian

A Pizzo - arxiv preprint arxiv:1511.07022, 2015‏ - arxiv.org
In this paper we introduce a novel multi-scale technique to study many-body quantum
systems where the total number of particles is kept fixed. The method is based on Feshbach …
