Description: Plasmas (or ionized gases) are often referred to as a “fourth” state of matter – but perhaps, they should be the “first”. This is because the plasmas are the most common state (over 95%) of matter in the visible universe. From technologies such as fluorescent lighting and microelectronics manufacturing to natural systems such as lightning, the aurora, and the solar wind, plasmas are ubiquitous in our lives. Even more remarkably, over the last three decades plasma scientists have learned how to control a certain type of plasma – a “complex” or “dusty” plasma – to make it have solid-like, fluid-like, or gas-like properties. This means that dusty plasmas are not just a fourth state of matter – they can take on the properties of all four states of matter. This presentation will provide an introduction to the physics and applications of plasmas and will describe some of the fascinating aspects of complex/dusty plasma research – including the one-of-a-kind, high magnetic field dusty plasma laboratory that has recently begun operating at Auburn.
