Interaction of Hawking radiation with static sources outside a Schwarzschild black hole

We show that the response rate of (i) a static source interacting with Hawking radiation of massless scalar field in Schwarzschild spacetime (with the Unruh vacuum) and that of (ii) a uniformly accelerated source with the same proper acceleration in Minkowski spacetime (with the Minkowski vacuum) are equal. We show that this equality will not hold if the Unruh vacuum is replaced by the Hartle-Hawking vacuum. It is verified that the source responds to the Hawking radiation near the horizon as if it were at rest in a thermal bath in Minkowski spacetime with the same temperature. It is also verified that the response rate in the Hartle-Hawking vacuum approaches that in Minkowski spacetime with the same temperature far away from the black hole. Finally, we compare our results with others in the literature.Comment: 18 pages (REVTEX

George F. Rohrlich Collection 1938-1994

The bulk of the collection consists of materials documenting the planning of the 50th reunion of Harvard Refugee Scholars. There are also a few materials documenting the establishment of the Harvard Refugee Scholar program.Georg Rohrlich was born into a middle-class Jewish family in Vienna, Austria, on January 6, 1914. He attended a modern Gymnasium (1924-32) and earned a doctorate in jurisprudence at the University of Vienna (1937). He emigrated to the United States in September 1938. In autumn 1939, he was accepted into Harvard University's newly-established scholarship program for refugees, the Harvard Refugee Scholar program. He earned a doctorate in political economy and government in 1943. and became an American citizen in June 1944.Rohrlich's career as a social welfare administrator began in 1947, when he served as a civilian economist for the Allied Powers in Tokyo and helped to re-establish Japan's social security system. After his return to the United States, he worked for the Social Security Administration (1950-53) and for the Department of Labor (1953-59). He then took a post with the International Labor Organization, an agency of the United Nations, and administered a training program for social security officials from underdeveloped nations (1959-64).Rohrlich re-entered the academic world in 1964. After three years at the University of Chicago's School of Social Science Administration (1964-67), he moved to Temple University's School of Business Administration, where he remained until his retirement in 1981.Between 1989 and 1991, Rohrlich helped to organize a fiftieth reunion of the Harvard Refugee Scholars (June 1990) and wrote a short history of the program.He died on August 21, 1995.See also "The Story of the Harvard Refugee Scholars" (MS 259)See also Georg F.

Mein Leben in Oesterreich vor und nach dem 11. Maerz 1938.

Memoirs written for Havard competition.Georg Rohrlich describes his childhood in Vienna, including his parents' divorce, his time with the boy scouts (Pfadfinder), his friendships with Jewish and gentile classmates, his time at the University of Vienna and antisemitic encounters there, the "Anschluss", and how he left Vienna on a Dutch airplane in 1938.Georg Rohrlich was born into a middle-class Jewish family in Vienna, Austria, on January 6, 1914.
