We investigate the diffusion of linguistic innovations on a fully connected network to understand the emergence of linguistic diversity. We employ an agent-based dynamics based on the Axelrod model, where interactions between agents are dri...
Complex dynamics and multistability of driven diatomic molecules revealed by numerical modeling of shifted molecular potentials [0.03%]

We have explored the nonlinear dynamics of six common, driven, diatomic molecules using a shifted Tietz-Wei (sTW) model of their molecular potential functions. We focused on the variations in their resonances, bifurcations and multistabilit...

Slowly modulated nonlinear waves are accurately described in the framework of the conservative nonlinear Schrödinger equation (NLS). However, in many physical systems, the wave evolution is affected by energy gains and losses, therefore re...
Hydrodynamic equations for a system with translational and rotational dynamics [0.03%]

We obtain the equations of fluctuating hydrodynamics for many-particle systems whose microscopic units have both translational and rotational motion. The orientational dynamics of each element are studied in terms of Langevin equations for ...
Exact statistics of helical wormlike chains with twist-bend coupling [0.03%]

We present a solution for the Green's function for the general case of a helical wormlike chain with twist-bend coupling and demonstrate the applicability of our solution for evaluating general structural and mechanical chain properties. We...

In this work, we extensively explore the thermodynamic properties of Brownian particles moving in an underdamped medium. Extending our previous analysis [Phys. Rev. E 101, 012131 (2020)10.1103/PhysRevE.101.012131], we examine systems subjec...

We describe and analyze a generalization of the classic "Four Bugs on a Square" cyclic pursuit problem. Instead of allowing the bugs to spiral towards one another, we constrain N bugs to the perimeter of the unit circle. Depending on their ...

A quantum thermal diode, similar to an electronic diode, allows for unidirectional heat transmission. In this paper, we study a quantum thermal diode composed of two two-level atoms coupled to auxiliary two-level atoms. We find that while e...

Notch signaling is a ubiquitous and versatile intercellular signaling system that drives collective behaviors and pattern formation in biological tissues. During embryonic development, Notch is involved in generation of collective biochemic...

In the frequency power spectral density, periodic oscillations appear as a Dirac comb at integer multiples of the frequency of the period. In weakly nonlinear systems or systems close to the primary instability threshold, the periodicity ma...
