SUMMARY:Microchips for cold atoms: from quantum science to portable devices
DESCRIPTION:Featuring Professor Peter Kruger\, Nottingham University\n\nPar
	t of the Physics Department Colloquia Series.\n\nThe field of ultracold ato
	ms links atomic and condensed matter physics. The development of laser cool
	ing and trapping techniques\, including the ability to routinely produce qu
	antum degenerate gases\, has advanced to the point where non-trivial comple
	x quantum systems can be prepared and controlled\, and their subsequent evo
	lution can be observed. This ability opens the path to investigations of no
	n-equilibrium dynamics of interacting quantum many-body systems and device-
	oriented quantum technology development alike.\nIn this talk we will introd
	uce the concept of an atom chip and show how such a miniaturized and integr
	ated manipulation toolbox for quantum gases leads to a large variety of new
	 possibilities for both fundamental science and applied technology. We will
	 discuss first cold atom devices that are already leaving the laboratory. A
	t the same time\, new materials and geometries\, such as graphene films\, p
	rovide means to further miniaturization. Here the separation of a nanokelvi
	n trapped gas and a room-temperature solid can be reduced to well within a 
	micron. New possibilities for studies of dynamics arise in this regime\, in
	 which the gas’s environment can be tailored with a resolution beyond rel
	evant intrinsic length scales (healing length). Conversely\, a quantum gas 
	trapped at a micron or less distance from a surface is a highly sensitive p
	robe for structure and transport within the solid\, where high spatial reso
	lution and field sensitivity are uniquely combined.
