For years, physicists were unable to take advantage of the advancements in computer algebra. Most systems were simply not able to handle the specialized rules and operators, non-commutative variables, and complex notation used regularly in physics calculations, with the result that physicists continued to find it easier to work their problems with pencil and paper. Fortunately, the situation has changed, with new advancements being made all the time that make the complex calculations of physics easier and more reliable.
In this webinar, learn more about recent advancements in computational physics, and see how these techniques can be applied to problems from general relativity, classical mechanics, quantum mechanics, and classical field theory. A recent project involving the digitization of the solutions to Einstein’s field equations shown in the book “Exact Solutions to Einstein’s Field Equations,” will also be presented.

Almost all clinics, small and large, use magnetic resonance images (MRI) in their treatment-planning workflows. Modern treatment planning requires images of high geometric fidelity with high spatial and contrast resolution to delineate disease extent and proximity to adjacent organs at risk. However, imaging protocols needed for accurate treatment planning differ significantly from those used in diagnostic radiology. As the integration of MRI into radiation oncology is expanding rapidly, a need exists to highlight the considerations for safe and effective implementation. This webinar will describe the major differences from diagnostic MRI, provide an overview of MRI safety and training models, introduce clinical-workflow considerations, and describe the development of a robust quality-assurance programme. Special considerations for motion management and treatment planning will be described.Read more >
After the first demonstration of an optical frequency comb based on a mode-locked laser in 1999, Ti:sapphire lasers with repetition rates around 1 GHz were the sources of choice for scientists around the world. Their key feature was a mode spacing 10 times higher than that of comparable 100 MHz sources (simplifying mode identification) and the ability to generate a fully coherent super-continuum with 100 times more power per mode either directly from the cavity or using an external microstructured fibre (enhancing signal-to-noise ratio). The world’s first optical atomic clock was built in 2001 using a 1 GHz Ti:sapphire laser and subsequently it has been shown that these lasers indeed support an accuracy at the 10–20 level with a 1 s stability at the 10–17 level and optical linewidths at the millihertz level, i.e. ideal candidate clockworks for a new generation of optical atomic clocks. The Ti:sapphire technology has even been taken out to as far as 10 GHz, a regime where individual modes with powers in excess of 1 mW can be separated with a grating spectrometer and used individually for direct spectroscopy, spectrograph calibration or optical arbitrary waveform generation.
To overcome some of the disadvantages of early Ti:sapphire lasers (requirement for frequent alignment, cleaning and use of AO modulators for control purposes) and to make the full advantages of GHz frequency comb technology accessible to the science community, Laser Quantum has developed the hermetically sealed and permanently aligned taccor 1 GHz Ti:sapphire laser featuring an integrated pump laser with direct pump power control. This intervention free laser forms the basis for the new taccor comb system featuring an f-2f interferometer and full comb-stabilization electronics.
This webinar reviews the benefits of gigahertz Ti:sapphire frequency combs and focuses on the recent progress using Laser Quantum‘s hermetically sealed line of taccor lasers.
The physics of electromagnetic coupling through space is fundamental to modern technology. It is exploited in some devices such as RFID tags and directional couplers to communicate information. In other devices, electromagnetic interference (EMI) is an unwanted effect that must be controlled: for example, the problem of crosstalk in electrical circuits and cables. In this webinar we will discuss the simulation of electromagnetic coupling in a variety of different applications, considering examples of capacitive, inductive and radiative couplings in frequencies from the kHz to GHz range. We will show how modelling can provide insight into design, either to improve the quality of a communication device, or to mitigate EMI through effective electromagnetic shielding. A live demo will illustrate how to simulate antenna crosstalk using COMSOL Multiphysics®. We will conclude this webinar with a Q&A session.Read more >
