Integrable Many - Body Systems and Gauge Theories
The review studies connections between integrable many-body systems and gauge theories. It is shown how the degrees of freedom in integrable systems are related with topological degrees of freedom in gauge theories. The relations between families of integrable systems and N = 2 supersymmetric gauge theories are described. It is explained that the degrees of freedom in the many-body systems can ...
متن کاملTime evolution of one-dimensional Quantum Many Body Systems
The level of current understanding of the physics of time-dependent strongly correlated quantum systems is far from complete, principally due to the lack of effective controlled approaches. Recently, there has been progress in the development of approaches for one-dimensional systems. We describe recent developments in the construction of numerical schemes for general (one-dimensional) Hamilton...
متن کاملEfficient simulation of one-dimensional quantum many-body systems.
We present a numerical method to simulate the time evolution, according to a generic Hamiltonian made of local interactions, of quantum spin chains and systems alike. The efficiency of the scheme depends on the amount of entanglement involved in the simulated evolution. Numerical analysis indicates that this method can be used, for instance, to efficiently compute time-dependent properties of l...
متن کاملGauge invariance in quantum hadrodynamics
This paper describes the derivation of a new representation of an SU(2)L× SU(2)R locally-invariant model of the strong interactions called quantum hadrodynamics 3 (QHD-III). QHD-III is a gauge-invariant theory based on the linear σ model, the gauge bosons being the ρ and the a1. The new representation considerably simplifies the lagrangian. To derive the new representation, the gauge invariance...
متن کاملTwo-Dimensional Quantum Gravity in Temporal Gauge
We propose a new type of gauge in two-dimensional quantum gravity. We investigate pure gravity in this gauge, and find that the system reduces to quantum mechanics of loop length l. Furthermore, we rederive the c=0 string field theory which was discovered recently. In particular, the pregeometric form of the Hamiltonian is naturally reproduced. To be published in Nuclear Physics B ∗ e-mail addr...
