Steuard Jensen (with Jeff Harvey).  "Worldsheet instanton corrections to the Kaluza-Klein monopole."  Journal of High Energy Physics.  Volume 2005. Number 10. p. 28.  October 11, 2005.

More Details:

The Kaluza-Klein monopole is a well known object in both gravity and string theory, related by T-duality to a "smeared" NS5-brane which retains the isometry around the duality circle. As the true NS5-brane solution is localized at a point on the circle, duality implies that the Kaluza-Klein monopole should show some corresponding behavior. In this paper, we express the Kaluza-Klein monopole as a gauged linear sigma model in two dimensions and show that worldsheet instantons give corrections to its geometry. These corrections can be understood as a localization in "winding space" which could be probed by strings with winding charge around the circle.

 

Alma College’s early acceptance agreement with the Michigan State University College of Human Medicine recognizes the College’s strengths in science and health education. The agreement reserves two admissions slots per year for Alma College pre-med graduates.

Prof. Sandy Lopez-Isnardi

Prof. Sandy Lopez-Isnardi
Departments: Art and Design

In the print “Sands of Time” dark shadows and textures come together with silver and grey tones to form an almost surreal beach setting. Sandy Lopez-Isnardi, associate professor of art and design, has been making traditional gelatin prints like this for more than 20 years. Her work also includes non-silver and chromogenic prints and most recently has focused on the Midwestern landscape in photography. Her digital work is experimental, including two-dimensional and installation works.
