Optimal transport by a Lagrangian dynamics of population distribution
Babak Benam, Abolfazl Ramezanpour
Human mobility, enabled by diverse transportation modes, is fundamental to urban functionality. Studying these movements across scales-from microscopic to macroscopic-yields valuab…
Messenger size optimality in cellular communications
Arash Tirandaz, Abolfazl Ramezanpour, Vivi Rottschäfer +3
Living cells presumably employ optimized information transfer methods, enabling efficient communication even in noisy environments. As expected, the efficiency of chemical communic…
Efficiency of energy-consuming random walkers: Variability in energy helps
Mohsen Ghasemi Nezhadhaghighi, Abolfazl Ramezanpour
Energy considerations can significantly affect the behavior of a population of energy-consuming agents with limited energy budgets, for instance, in the movement process of people…
Loop corrections for hard spheres in Hamming space
Abolfazl Ramezanpour, Saman Moghimi-Araghi
We begin with an exact expression for the entropy of a system of hard spheres within the Hamming space. This entropy relies on probability marginals, which are determined by an ext…
Bethe free-energy approximations for disordered quantum systems
I. Biazzo, A. Ramezanpour
Given a locally consistent set of reduced density matrices, we construct approximate density matrices which are globally consistent with the local density matrices we started from…
Low-temperature excitations within the Bethe approximation
I. Biazzo, A. Ramezanpour
We propose the variational quantum cavity method to construct a minimal energy subspace of wave vectors that are used to obtain some upper bounds for the energy cost of the low-tem…
