Quantum computers have the potential to provide quadratic speedup for Monte Carlo methods currently used in various classical applications. In this work, we examine the advantage of quantum computers for financial option pricing with the Monte Carlo

Recent studies have demonstrated the efficiency of Variational Autoencoders (VAE) to compress high-dimensional implied volatility surfaces into a low dimensional representation. Although this method can be effectively used for pricing vanilla options

Game theory is one of the key paradigms behind many scientific disciplines from biology to behavioral sciences to economics. In its evolutionary form and especially when the interacting agents are linked in a specific social network the underlying so

The purpose of this paper is to understand buyer/seller adoption dynamics in independent, buyer-side B2B exchanges. In a stylized model, we assume that the main role of the exchange is to reduce search costs for buyers. Buyers and sellers enter or ex

The Ginzburg-Landau (GL) and Schr\"odinger equations with a nonuniform magnetic flux density $\mathbf{B}(\mathbf{r})$ admit a class of internally orthogonal solutions with $\ensuremath{\nabla}g=\ensuremath{-}\ensuremath{\nabla}\mathrm{ln}|\ensuremath

The behavior of Haldane-gap antiferromagnets in a strong magnetic field is not universal. While the low-energy physics of the conventional one-dimensional spin-1 Heisenberg model in its magnetized regime is described by one incommensurate soft mode,

The Schrodinger equation for an interacting spinless electron gas in a nonuniform magnetic field admits an exact solution in Jastrow product form when the fluctuations in the magnetic field track the fluctuations in the scalar potential. For tracking

In the quasi-one-dimensional antiferromagnets CsMnBr${}_{3}$ and RbMnBr${}_{3}$ the magnetization produced by an external magnetic field displays a much stronger dependence upon the direction of the field than expected from calculations done for a sy

White's density-matrix renormalization-group (DMRG) method has been applied to the one-dimensional Ising model in a transverse field (ITF), in order to study the accuracy of the numerical algorithm. Due to the exact solubility of the ITF for any fini
