DSQSS: Discrete Space Quantum Systems Solver
نویسندگان
چکیده
The Discrete Space Quantum Systems Solver (DSQSS) is a program package for solving quantum many-body problems defined on lattices. DSQSS based the Monte Carlo method in Feynman's path integral representation and covers broad range of using flexible input files that define arbitrary unit cells dimensions matrix elements representing interactions among an number degrees freedom. Finite temperature calculations spin Bose- Hubbard models can be performed by specifying parameters such as dimensions, lattice size, coupling constants, temperature. present paper details use presents applications thereof.

Quantum Mechanics on Discrete Space and Time
We propose the assumption of quantum mechanics on a discrete space and time, which implies the modification of mathematical expressions for some postulates of quantum mechanics. In particular we have a Hilbert space where the vectors are complex functions of discrete variable. As a concrete example we develop a discrete analog of the one-dimensional quantum harmonic oscillator, using the depend...
متن کاملState space synthesis of discrete linear systems
The target of this paper is to draw attention to some important relations between different procedures of state space synthesis of discrete linear systems optimizing the quadratic cost function. Common form of the synthesis concerns one-dimensional and multi-dimensional control problems solved by Second Method of Lyapunov, Maximum Principle of Pontryagin and by Bellamn's Dynamic Programming. Em...
متن کاملParagrassmann Integral, Discrete Systems and Quantum Groups
This report is based on review paper [1]. Some aspects of differential and integral calculi on generalized grassmann (paragrassmann) algebras are considered. The integration over paragrassmann variables is applied to evaluate the partition function for the Z p+1 Potts model on a chain. Finite dimensional paragrassmann representations for GL q (2) are constructed. Generalizations of grassmann al...
متن کاملQuantum Dynamical Systems with Quasi–Discrete Spectrum
We study totally ergodic quantum dynamical systems with quasi–discrete spectrum. We investigate the classification problem for such systems in terms of algebraic invariants. The results are noncommutative analogs of (a part of) the theory of Abramov. Supported in part by the National Science Foundation under grant DMS–9801612
متن کاملA Geometric Renormalisation Group in Discrete Quantum Space-Time
We model quantum space-time on the Planck scale as dynamical networks of elementary relations or time dependent random graphs, the time dependence being an effect of the underlying dynamical network laws. We formulate a kind of geometric renormalisation group on these (random) networks leading to a hierarchy of increasingly coarse-grained networks of overlapping lumps. We provide arguments that...
