Gauge Equivariant Neural Networks for Quantum Lattice Gauge Theories
Gauge symmetries play a key role in physics appearing in areas such as quantum field theories of the fundamental particles and emergent degrees of freedom in quantum materials. Motivated by the desire to efficiently simulate many-body quantum systems with ...
AMER PHYSICAL SOC2021Conformal 3-Point Functions and the Lorentzian OPE in Momentum Space
In conformal field theory in Minkowski momentum space, the 3-point correlation functions of local operators are completely fixed by symmetry. Using Ward identities together with the existence of a Lorentzian operator product expansion (OPE), we show that t ...
SPRINGER2020Generalized reduced basis methods and n-width estimates for the approximation of the solution manifold of parametric PDEs
Alfio Quarteroni, Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila
The set of solutions of a parameter-dependent linear partial differential equation with smooth coefficients typically forms a compact manifold in a Hilbert space. In this paper we review the generalized reduced basis method as a fast computational tool for ...
Springer2012A Reduced Basis Method for Evolution Schemes with Parameter-Dependent Explicit Operators
During the last decades, reduced basis (RB) methods have been developed to a wide methodology for model reduction of problems that are governed by parametrized partial differential equations (PPDEs). In particular equations of elliptic and parabolic type f ...
