The phase behavior of a quasi-one-dimensional fluid of hard spheres is studied in hard cylindrical and rectangular straight channels using the transfer operator method. The radius of the channel (R) is chosen such that only first-neighbor i...

We calculate the eigenvalues of a class of random matrices, namely, the randomly segmented tridiagonal quasi-Toeplitz matrix (rstq-T), in exact closed form. The contexts under which these matrices arise are ubiquitous in physics. In our cas...

We study the decay of tangential velocity profiles with distance from a local disturbance in hard-sphere colloidal suspensions as the colloidal glass transition is approached. The disturbance, generated by a dimer of superparamagnetic parti...

The unique geometry of the two-dimensional tripartite Kagome lattice is responsible for shaping diverse families of spatially localized and time-periodic nonlinear modes, known as discrete breathers. We state conditions for the existence of...

This work presents a lattice Boltzmann (LB) model for immiscible multiphase flow with phase change. By integrating the pseudopotential model with the color-gradient model, the current model is capable of capturing phase change spontaneously...

Landau-damped oscillations in collisionless plasmas, described by van Kampen and Case, are quasimodes, representing a continuous superposition of singular eigenfunctions, not true eigenmodes. Recent work by Ng et al. shows that even rare co...
Generation of non-Maxwell-Boltzmann energy distributions during thermalization of interacting baths [0.03%]

We report on numerical experiments of thermalization between two reservoirs in which interspecies interactions are mediated via a Hamiltonian with a Gaussian dependence upon the distance between the particles. By using relatively high stati...
Mechanistic insights into air discharge mode transition: Revealing the indispensible roles of N_{2}(v) and N_{2}O_{5} [0.03%]

The phenomenon of discharge mode transition in air plasmas, which refers to the selective production of reactive species under different external conditions, has been a longstanding issue and has regained major attention recently due to eme...

The anticipating synchronization in an ensemble of electrochemical cell oscillators exhibiting chaotic dynamics is analyzed. Using a setup up of up to three oscillators, it is observed that when such systems are coupled by unidirectional de...
