Closed-form solutions for the Salpeter equation
Fernando Alonso-Marroquin, Yaoyue Tang, Fatemeh Gharari +1
We propose integral representations and analytical solutions for the propagator of the dimensional Salpeter Hamiltonian, describing a relativistic quantum particle with no sp…
Stylized Facts of High-Frequency Bitcoin Time Series
Yaoyue Tang, Karina Arias-Calluari, M. N. Najafi +2
This paper analyses the high-frequency intraday Bitcoin dataset from 2019 to 2022. During this time frame, the Bitcoin market index exhibited two distinct periods, 2019-20 and 2021…
Variable order porous media equations: Application on modeling the S&P500 and Bitcoin price return
Yaoyue Tang, Fatemeh Gharari, Karina Arias-Calluari +2
This article reveals a specific category of solutions for the Variable Order (VO) nonlinear fractional Fokker-Planck equations. These solutions are formulated using VO -Ga…
Stochastic and deterministic dynamics in networks with excitable nodes
Milad Rahimi-Majd, Juan G. Restrepo, Morteza Nattagh-Najafi
The analysis of the dynamics of a large class of excitable systems on locally tree-like networks leads to the conclusion that at a continuous phase transition takes place, wh…
Flicker Noise in Two-Dimensional Electron Gas
M. N. Najafi, S. Tizdast, Z. Moghaddam +1
Using the method developed in a recent paper (Euro. Phys. J. B 92.8 (2019): 1-28) we consider noise in two-dimensional electron gas (2DEG). The electron coherence length of t…
Coupling of and and conformal field theories: The geometrical point of view
M. N. Najafi
The coupling of the , and conformal field theories are numerically considered in this paper. As the prototypes of the couplings, $(c_1=-2)\oplus (c_2=0)…
