Boosting Binomial Exotic Option Pricing with Tensor Networks
Maarten van Damme, Rishi Sreedhar, Martin Ganahl
Pricing of exotic financial derivatives, such as Asian and multi-asset American basket options, poses significant challenges for standard numerical methods such as binomial trees o…
A critical lattice model for a Haagerup conformal field theory
Robijn Vanhove, Laurens Lootens, Maarten Van Damme +4
We use the formalism of strange correlators to construct a critical classical lattice model in two dimensions with the \emph{Haagerup fusion category} as input data…
Variational methods for contracting projected entangled-pair states
Laurens Vanderstraeten, Lander Burgelman, Boris Ponsioen +5
The norms or expectation values of infinite projected entangled-pair states (PEPS) cannot be computed exactly, and approximation algorithms have to be applied. In the last years, m…
Efficient MPS methods for extracting spectral information on rings and cylinders
Maarten Van Damme, Robijn Vanhove, Jutho Haegeman +2
Based on the MPS formalism, we introduce an ansatz for capturing excited states in finite systems with open boundary conditions, providing a very efficient method for computing, e.…
Riemannian optimization of isometric tensor networks
Markus Hauru, Maarten Van Damme, Jutho Haegeman
Several tensor networks are built of isometric tensors, i.e. tensors satisfying . Prominent examples include matrix product states (MPS) in canonical form…
Tangent-space methods for truncating uniform MPS
Bram Vanhecke, Maarten Van Damme, Jutho Haegeman +2
A central primitive in quantum tensor network simulations is the problem of approximating a matrix product state with one of a lower bond dimension. This problem forms the central…
Real-time scattering of interacting quasiparticles in quantum spin chains
Maarten Van Damme, Laurens Vanderstraeten, Jacopo De Nardis +2
We develop a method based on tensor networks to create localized single particle excitations on top of strongly-correlated quantum spin chains. In analogy to the problem of creatin…
