Classical fractional time series from quantum XXZ spin chains
Zoltán Udvarnoki, Gábor Fáth, Miklós Werner +1
Entangled quantum mechanical states in one dimension can be used to represent and simulate classical stochastic processes with nontrivial statistical properties. Long-range quantum…
Deep Weighted Monte Carlo: A hybrid option pricing framework using neural networks
Sándor Kunsági-Máté, Gábor Fáth, István Csabai +1
Recent studies have demonstrated the efficiency of Variational Autoencoders (VAE) to compress high-dimensional implied volatility surfaces into a low dimensional representation. Al…
Evolutionary games on graphs
Gyorgy Szabo, Gabor Fath
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 intera…
Logarithmic delocalization of end spins in the S=3/2 antiferromagnetic Heisenberg chain
Gabor Fath, Ors Legeza, Peter Lajko +1
Using the DMRG method we calculate the surface spin correlation function, , in the spin antiferromagnetic Heisenberg chain. For comparison we a…
Probable absence of a quadrupolar spin-nematic phase in the bilinear-biquadratic spin-1 chain
K. Buchta, G. Fáth, Ö. Legeza +1
We study numerically the ground-state phase diagram of the bilinear-biquadratic spin-1 chain near the ferromagnetic instability point, where the existence of a gapped or gapless no…
A renormalization group theory of cultural evolution
Gabor Fath, Miklos Sarvary
We present a theory of cultural evolution based upon a renormalization group scheme. We consider rational but cognitively limited agents who optimize their decision making process…
