Between classical and quantum

- N. P. Landsman
- Mathematics, Physics
- 10 June 2005

The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it. Our discussion of this… Expand

A Topos for Algebraic Quantum Theory

- C. Heunen, N. P. Landsman, Bas Spitters
- Mathematics, Physics
- 27 September 2007

The aim of this paper is to relate algebraic quantum mechanics to topos theory, so as to construct new foundations for quantum logic and quantum spaces. Motivated by Bohr’s idea that the empirical… Expand

Real- and imaginary-time field theory at finite temperature and density

- N. P. Landsman, C. V. Weert
- Physics
- 1987

Abstract This report gives a detailed account of relativistic quantum field theory in the grand canonical ensemble. Three approaches are discussed: traditional Euclidean Matsubara, and two recently… Expand

Observation and superselection in quantum mechanics

- N. P. Landsman
- Physics
- 23 November 1994

Abstract We attempt to clarify the main conceptual issues in approaches to ‘objectification’ or ‘measurement’ in quantum mechanics which are based on superselection rules. Such approaches venture to… Expand

Quantization of Poisson algebras associated to Lie algebroids

- N. P. Landsman, B. Ramazan
- Mathematics, History
- 4 January 2000

We prove the existence of a strict deformation quantization for the canonical Poisson structure on the dual of an integrable Lie algebroid. It follows that any Lie groupoid C*-algebra may be regarded… Expand

Strict deformation quantization of a particle in external gravitational and Yang-Mills fields

- N. P. Landsman
- Mathematics
- 1 August 1993

An adaptation of Rieffel's notion of “strict deformation quantization” is applied to a particle moving on an arbitrary Riemannian manifold Q in an external gauge field, that is, a connection on a… Expand
