We study numerically the kinetic roughening properties of the precursor fronts of nonvolatile liquid droplets spreading on solid substrates, for the case of circular droplets, more frequently addressed in experiments. To this end, we perfor...
Stochastic radiative transfer in random media. III. Effective opacity [0.03%]

Homogenization of random media is a practical approach to efficiently simulate stochastic radiative transfer, which requires establishing a reliable effective opacity model. In this work, a new effective opacity model is developed by consid...

Graph neural networks can accurately predict the chemical properties of many molecular systems, but their suitability for large, macromolecular assemblies such as gels is unknown. Here, graph neural networks were trained and optimized for t...

Ultrashort pulsed lasers can produce thin columns of plasma in the air via femtosecond filamentation, and these plasmas have been found to generate broadband terahertz and radio frequency (RF) radiation. A recent theory argues that the curr...

During quasistatic dynamics of granular systems, the stress and structure self-organize, but there is currently no quantitative measure or understanding of this phenomenon. Such an understanding is essential because local structural propert...

It is well established that the ferromagnetic phase remains stable under random magnetic fields in three and higher dimensions for the ferromagnetic Ising model and the Edwards-Anderson model of spin glasses without correlation in the disor...

We derive an expression for the exact probability Pr[i∼j] of a link between a node i with degree d_{i} and a node j with degree d_{j} in a graph belonging to the class of Erdős-Rényi G(N,L) random graphs with N nodes and L links. The pro...

Theory and experiment have long discussed negative thermodynamic pressure states, but their microscopic origins are unclear. I address this problem within the framework of quantum thermodynamics. I show that the pressure exerted on the boun...
Discrete-time walk on one-dimensional lattice under stochastic resetting: Advantage of quantum over classical scenario [0.03%]

We investigate the effect of stochastic restart/resetting on discrete-time quantum walks concerning its impact on the meantime to absorption in the walk on the one-dimensional lattice terminated by a pair of totally absorbing sites. The two...

Quantum harmonic oscillators coupled through coordinates and momenta, represented by the Hamiltonian H[over ̂]=∑_{i=1}^{2}(p[over ̂]_{i}^{2}/2m_{i}+m_{i}ω_{i}^{2}/2x_{i}^{2})+H[over ̂]_{int}, where the interaction of two oscillators H[...
