The first a part of this booklet comprises E. Lieb's basic contributions to the mathematical conception of Condensed subject Physics. frequently thought of the founder of the sector, E. Lieb demonstrates his skill to choose crucial matters and to formulate them as well-defined mathematical difficulties and, ultimately, to unravel them. the second one half offers Lieb's paintings on integrable types. His groundbreaking articles helped to set up precisely Soluble versions as a flourishing examine box in its personal correct. The papers gathered during this quantity have additionally been rigorously annotated via the editors.

Pauli and the Spin-Statistics Theorem

This booklet goals to make generally obtainable an comprehensible facts of the notorious spin-statistics theorem. This widely recognized yet little-understood theorem is meant to give an explanation for the truth that electrons obey the Pauli exclusion precept. This truth, in flip, explains the periodic desk of the weather and their chemical homes.

Elementary particles; a short history of some discoveries in atomic physics

Whilst in 1957 Chen Ning Yang, along with his colleague Tsung Dao Lee, steered that, in layman's phrases, the correct- and left-handed simple materials of topic behaved another way, and while scan proven that the legislation of nature do distinguish among a procedure and its replicate snapshot, our wisdom of primary actual rules took one of many surprising turns that have characterised its background.

Example text

The shortest proof is to return to H and the SZ -0 subspace (in the original variables). For each U > 0 the ground state "'(U) is nondegenerate as has been shown and I want to prove that 2S -I B 1 - 1A I. The nondegeneracy of the ground state for all U> 0 implies that the S of this unique ground state must be independent of U, for otherwise continuity in U would imply a degeneracy for some value of U > O. However, when U is very large, H, as stated before, is equivalent (to leading order in U) to h, the Heisenberg antiferromagnetic Hamiltonian defined in remark (4).

Lieb Departments of Physics and Mathematics. Princeton University. P. 0. Box 708. Princeton. New Jersey 08544 (Received 12 December 1988) In the attractive Hubbard model (and some extended versions of it), the ground state is proved to have spin angular momentum S =0 for every (even) electron filling. In the repulsive case, and with a bipartite lattice and a half-filled band, the ground state has S - t II B I - I A II, where IB I (I A I) is the number of sites in the B (A) sublattice.
