Roy Glauber, a Nobel doctor and Harvard physics professor, dies at 93 – Harvard Gazette

Roy J. Glauber, 46, the pioneering theoretical physicist, who received the Nobel Prize in 2005 and was one of the last living scientists present during the dawn of the atomic age, died on December 26, 2018. He were 93

The investigation that set Glauber on the road to Nobel began his interest in a terrible experiment of 1956, which confirmed a key concept of quantum physics – that light was so particle and wave – and put the foundation for the field. His 1963-paper landmark, "The Quantum Theory of Optical Coherence", used quantum mechanical tools to transform the understanding of light science, which was previously only studied using classical techniques.

"We really did not have a full understanding of the quantum properties of light, and what Roy's work was a framework to think about," said Mikhail Lukin, the George Vasmer Leverett Physics Professor and co-director of Quantum Science and Engineering. "It allowed us to think about these types of questions in a large amount … so I would argue that his work has cost the foundation for the chemical science and technology that people are talking about now."

Lukin said that the theories described by Glauber have opened the door for many scientific discoveries and also new generations, including quantum computers and networks and the use of quantum cripta, which depends on quantum mechanics to create impossible crack codes.

"These ideas all grow from this framework he developed," said Lukin. "Some people talk about these new developments as the second quantum revolution – the first was to understand the laws of quantum mechanics. But in this second revolution … the idea is that we now understand the quantum world and we are actually If we can check it, let's see what we can use it. Can we build materials with the properties you need to design? Can we build up quantities of computers? Can we build up quantities where we can send information with absolute security of one side of the country to the other? These types of ideas are very dependent on understanding where the class world ends and the quantum world begins, and here, where Roy's ideas have pioneered and developed have become absolutely critical. "

Glauber graduated from the Bronx High School of Science and entered Harvard as a 17-year-old novice, but left as sophomore when he was recruited to join the Manhattan Project, where he worked with the future Nobel-winning physicist Richard Feynman to calculate the critical mass of the first atomic bomb. Glauber later attended the bomb's first attempts.

After World War II, he returned to Harvard to finish his students and then get Ph.D. After receiving his doctorate he was promoted to a position at the Robert Oppenheimer Institute for Advanced Study, and worked there before returning to Harvard in 1952, where he spent the remnants of his career.

Although he was seriously known about his scientific work, friends said Glauber was not lighter. For years, he was a "keeper of the trimmer", releasing the stage of aircraft aircraft launched during the Ig Nobel Prize's annual ceremony recognizing unusual or insignificant scientific achievements.

One of the few years Glauber missed the Ig Nobel ceremony was in 2005 – because he was in Stockholm gathering his real Nobel.

"I think he has carried out his role at the Ig Noble ceremony," said Arthur Jaffe, the Land T. Clay teacher of Mathematics and Theoretical Science. "He loved to describe smiling his role as the doorman, sweeping the stage at the end of the presentation."

In his free time, Jaffe said, Glauber was interested in classical music. He and his companion, Atholie Rosett, have occasionally hosted events for one local performance in their home.

"People consider him a father of … a huge area of ​​physics that was very prolific in modern life," said Jaffe. "He always had a very clear opinion on his estimation by other scientists. He personally remained modest, his character has not changed since the Nobel Prize has not changed."

Irwin Shapiro, the Timken University Professor, met Glauber for more than six decades, first as a student and later as his colleague. He credits Glauber making sure he got his first job after receiving his Ph.D.

"He was only four years older than me, and he called the head of the MIT Lincoln Laboratory, who thought to contract me and suggested, without uncertainty that he did that," said Shapiro.

Although both grew up in New York City, they never met before Shapiro became the first doctor of Glauber.

"One anecdote that made him laugh when I told him when I first became his counselor in 1952, I told my mother about it and mentioned the name of Roy as my adviser," Shapiro remembered. "She mentioned it slightly to her younger sister, who shouted and said:" Oh, Felicia's little boy, Roy! "I do not know how my aunt knew Roy's mother, but somehow they were friends."

Glauber is survived by his son, Jeffrey, daughter, Valerie Glauber Fleishman; sister, Jacqueline Gordon; Rosett, his 13-year-old companion; and five grandsons.
