The high density region of QCD in a large mass and chemical potential model
Roberto De Pietri, Alessandra Feo, Erhard Seiler +1
We study the high density region of QCD within an effective model obtained in the frame of the hopping parameter expansion. The model still acknowledges the sign problem peculiar t…
apeNEXT: A multi-TFlops Computer for Simulations in Lattice Gauge Theory
F. Bodin, Ph. Boucaud, N. Cabibbo +19
We present the APE (Array Processor Experiment) project for the development of dedicated parallel computers for numerical simulations in lattice gauge theories. While APEmille is a…
The apeNEXT project (Status report)
F. Bodin, Ph. Boucaud, J. Micheli +18
We present the current status of the apeNEXT project. Aim of this project is the development of the next generation of APE machines which will provide multi-teraflop computing powe…
Status of the apeNEXT project
R. Ammendola, F. Bodin, Ph. Boucaud +27
We present the current status of the apeNEXT project. Aim of this project is the development of the next generation of APE machines which will provide multi-teraflop computing powe…
The APENEXT project
F. Bodin, P. Boucaud, N. Cabibbo +31
APENEXT is a new generation APE processor, optimized for LGT simulations. The project follows the basic ideas of previous APE machines and develops simple and cheap parallel system…
Status of APEmille
APE-Collaboration, :, A. Bartoloni +31
This paper presents the status of the APEmille project, which is essentially completed, as far as machine development and construction is concerned. Several large installations of…
Matrix model formulation of four dimensional gravity
R. De Pietri
The attempt of extending to higher dimensions the matrix model formulation of two-dimensional quantum gravity leads to the consideration of higher rank tensor models. We discuss ho…
Hamiltonian LGT in the complete Fourier analysis basis
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
The main problem in the Hamiltonian formulation of Lattice Gauge Theories is the determination of an appropriate basis avoiding the over-completeness arising from Mandelstam relati…
The basis of the physical Hilbert space of lattice gauge theories
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
Non-linear Fourier analysis on compact groups is used to construct an orthonormal basis of the physical (gauge invariant) Hilbert space of Hamiltonian lattice gauge theories. In pa…
