Scaling exponents and phase separation in a nonlinear network model inspired by the gravitational accretion
Aleksandar Bogojevic, Antun Balaz, Aleksandar Belic
We study dynamics and scaling exponents in a nonlinear network model inspired by the formation of planetary systems. Dynamics of this model leads to phase separation to two types o…
SPEEDUP Code for Calculation of Transition Amplitudes via the Effective Action Approach
Antun Balaz, Ivana Vidanovic, Danica Stojiljkovic +3
We present Path Integral Monte Carlo C code for calculation of quantum mechanical transition amplitudes for 1D models. The SPEEDUP C code is based on the use of higher-order short-…
Fast Converging Path Integrals for Time-Dependent Potentials II: Generalization to Many-body Systems and Real-Time Formalism
Antun Balaz, Ivana Vidanovic, Aleksandar Bogojevic +2
Based on a previously developed recursive approach for calculating the short-time expansion of the propagator for systems with time-independent potentials and its time-dependent ge…
Properties of Quantum Systems via Diagonalization of Transition Amplitudes II: Systematic Improvements of Short-time Propagation
Ivana Vidanovic, Aleksandar Bogojevic, Antun Balaz +1
In this paper, building on a previous analysis [1] of exact diagonalization of the space-discretized evolution operator for the study of properties of non-relativistic quantum syst…
Fast Converging Path Integrals for Time-Dependent Potentials I: Recursive Calculation of Short-Time Expansion of the Propagator
Antun Balaz, Ivana Vidanovic, Aleksandar Bogojevic +2
In this and subsequent paper arXiv:1011.5185 we develop a recursive approach for calculating the short-time expansion of the propagator for a general quantum system in a time-depen…
Recursive Schr\" odinger Equation Approach to Faster Converging Path Integrals
Antun Balaz, Aleksandar Bogojevic, Ivana Vidanovic +1
By recursively solving the underlying Schr\" odinger equation, we set up an efficient systematic approach for deriving analytic expressions for discretized effective actions. With…
