Phase Transitions in the Hubbard Model on the Square Lattice
Zhituo Wang
We study the low temperature properties of the two-dimensional weakly interacting Hubbard model on $\ZZZ^2$ with renormalized chemical potential , fixed, in…
Corrected Loop Vertex Expansion for Phi42 Theory
Vincent Rivasseau, Zhituo Wang
This paper is an extended erratum to J. Math. Phys.53, 042302 (2012) and arXiv:1104.3443, in which the classic construction and Borel summability of the phi^4_2 Euclidean quantum f…
Construction of the noncommutative rank I Bergman domain
Zhituo Wang
In this paper we present a harmonic oscillator realization of the most degenerate discrete series representations of the SU(2,1) group and the deformation quantization of the coset…
How are Feynman graphs resumed by the Loop Vertex Expansion?
Vincent Rivasseau, Zhituo Wang
The purpose of this short letter is to clarify which set of pieces of Feynman graphs are resummed in a Loop Vertex Expansion, and to formulate a conjecture on the theory in n…
