JCMsuite is the finite element solver for the computation of electromagnetic waves in complex nano-optical systems. The continuum mechanics and heat conduction moduls allows for modeling complicated materials such as stress-induced birefringence.

The Journal of Computational Physics (JCP) focuses on the computational aspects of physical problems. JCP encourages original scientific contributions in advanced mathematical and numerical modeling reflecting a combination of concepts, methods and principles which are often interdisciplinary in nature and span several areas of physics ...

Time domain two-dimensional infrared (2DIR) spectroscopy extends the capabilities of traditional infrared spectroscopy by revealing information on vibrational modes’ anharmonicities, couplings, and ... Spin is a fundamental property of any many-electron system.

Numerical modeling of wave propagation in both homogeneous and heterogeneous media was performed using different SGFD schemes to further validate the conclusions obtained from the accuracy analysis. The errors in snapshots and waveforms …

2013年10月15日 · Plane wave pseudopotential (PWP) density functional theory (DFT) calculation is the most widely used method for material simulations, but its absolute speed stagnated due to the inability to use large scale CPU based computers.

2025年2月20日 · Waves are pivotal factors in coastal areas, and effective simulation of wave-related phenomena is crucial. This paper presents the extension of the non-hydrostatic model from single-layer σ transformation to double-layer σ transformation in order to stabilize submerged structures and jet orifices under wave environment. The Lagrangian ...

2006年11月16日 · In wave packet interferometry (WPI), the separation between the temporal envelopes of the pulses must be precisely monitored or maintained. Here we introduce a new (and easy to implement) experimental scheme for phase-selective measurements that combines acousto-optic phase modulation with ultrashort laser excitation to produce an intensity ...

2012年7月1日 · We develop new high-order accurate upwind schemes for the wave equation in second-order form. These schemes are developed directly for the equations in second-order form, as opposed to transforming the equations to a first-order hyperbolic system.

2022年2月15日 · In this paper, we focus on constructing numerical schemes preserving the averaged energy evolution law for nonlinear stochastic wave equations driven by multiplicative noise. We first apply the compact finite difference method and the interior penalty discontinuous Galerkin finite element method to discretize space variable and present two semi ...
