Lecture

Photonic Time-Crystals (PTCs) are materials in which the refractive index varies periodically and abruptly in time. They conserve momentum but not energy, and display momentum bands separated by gaps. The fundamentals of PTCs will be presented, with an emphasis on light-matter interactions ranging from light emission by atoms and free electrons to superluminal k-gap solitons and recent experiments on time-refraction at optical frequencies.

Speaker Bio

Mordechai “Moti” Segev is the Robert J. Shillman Distinguished Professor of Physics and Electrical Engineering, at the Technion, Israel. He received his BSc and PhD from the Technion in 1985 and 1990. After postdoc at Caltech, he joined Princeton as Assistant Professor (1994), becoming Associate Professor in 1997, and Professor in 1999. Subsequently, Moti went back to Israel, and in 2009 was appointed as Distinguished Professor.

Moti’s interests are mainly in photonics, solitons, lasers, and quantum optics. He won numerous international awards, among them the 2007 Quantum Electronics Prize of the European Physics Society, the 2009 Max Born Award of the Optical Society of America, and the 2014 Arthur Schawlow Prize of the American Physical Society. In 2011, he was elected to the Israel Academy of Sciences, in 2015 to the National Academy of Science (USA), and in 2021 to the American Academy of Arts and Sciences. In 2014 Moti Segev won the Israel Prize (highest honor in Israel) and in 2019 he has won the EMET Prize.

Above all his achievements, Moti takes pride in the success of his graduate students and postdocs, among them are currently 23 professors in the USA, Germany, Taiwan, Croatia, Italy, India, China and Israel, and many holding senior R&D positions in the industry.
