EPS-NA 2014-15 Annual Report

EPS-NA continues to attract more members and in 2014-2015 had the highest number of members who paid their membership fees (25 members). In 2015, 13 members including four executive members met at The American Physical Society (APS) in San Antonio. Dr. Guebre Xabiher Tessema participated through Skype.

A group picture of the participants after the meeting.

Dr. Amy Flatten greeted the members and made some remarks. Prof. Herman Winick of Stanford University came to the meeting and introduced the plans for building an African Light Source and asked EPS-NA to help get Ethiopians be part of the Steering committee. The meeting focused on how to engage members to be more active in the organization. Some of the suggestions include:

- Enhance the web page and provide more information and solicit members with expertise and time in web design to help.

- More presence on social media and face book was recommended. We ask all members to join the EPS-NA Facebook https://www.facebook.com/groups/epsna/.

- Encourage members to organize regional activities: Example mentioned was Dr. Guebre Xabiher Tessema participation in the Youth Mentoring program in Washington. Since it has been proven to be very challenging to organize a meeting for all members, meetings of regional representatives will help expand the activities of EPS in the US.

-Provide more opportunities to aspiring young Ethiopians in the US through networking with EPS Members.

- Declining enrollment of physics students in Physics departments in Ethiopia was raised as a concern and an opportunity for EPS-NA to get involved.

EPS-NA Award Program to Undergraduate and Graduate Physics majors in Ethiopia

EPS-NA Successfully conducted the 2014-2015 award competition in Ethiopia in collaboration with EPS-Ethiopia. EPS-NA recognized the following five undergraduate students and one graduate student for the 2014-15 EPS-NA awards.

  1. Under graduate junior:
    1. Yenesew Asradew Nibret, Debremarkos University
  2. Undergraduate senior:
    1. Jamal Assen Mohammed, Haramaya University

The competition was open to all physics departments in Ethiopia and the awards were given to more students outside AAU this year. The Executive Committee also decided to increase the amount of the award to $250 for each winner to have more impact on the lives of the winners.

In addition in 2014-15 EPS-NA received a request for a financial support from Mr. Shinie Shewangizaw. The support was needed to be able to pay the cost sharing to ministry of education in order to enroll in the Graduate program at AAU.

The EPS-NA- EC investigated the legitimacy of the request and received a strong letter of recommendation from Dr. Lemi. Mr. Shinie has the highest undergraduate GPA in his cohort. We believe Mr. Shinie Shewangizaw is a deserving student and has a strong potential to succeed. EPS-NA decided to make this one time award for $650 to help Mr. Shinie to enroll in the graduate program.

EPS-NA wanted to make sure the members also know who they are supporting and how membership fees are making a difference in the lives of Ethiopian Physicists in Ethiopia. We have therefore included (attached document) the profiles of each winner and their pictures and statements made by the winners.

We hope this profile will help you recognize the difference you are making in the lives of young needy Ethiopians who like us would like to succeed in life. So please send your membership fees and other donations to make more impact.

YOHANNES ACHENEFE- Graduate -Addis Ababa University

“I am from Debark, Gondar, where my family lives in farming. Because of this award I will be motivated to work harder in my research activities. The award also supplements the small research fund I was given by Addis Ababa University for dissertation writing and alleviate my financial burdens in my final semester.”


“Currently I teach in high school and I always miss the education environment in College. I am grateful that EPS-NA understands my desire to pursue my graduate study based on my application letter submitted to society. I would like to thank the Ethiopian physical society - North America for the financial support I got in order to pay off my cost sharing to the ministry of education. This clears my path to conduct my graduate program. I am very happy for this scholarship award” Recommendation by Dr. Lemi “He was a hard working and the best student, and based on his achievement in the aforementioned courses I found him at the top from out of forty students. Also, I know that he finished his undergraduate study with first rank in Physics Department with very great distinction, and narrowly missed the gold medal prize of the college. I have also noticed while instructing computational physics laboratory classes that he was a well mannered person of excellent spirit in team work.”

University of Minnesota engineers make sound loud enough to bend light on a computer chip. The PI in the article published in nature communication is Semere Tadesse, an Ethiopian graduate student at the department of Physics and Astronomy.

MINNEAPOLIS / ST. PAUL (11/26/2014)—During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That’s because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).

Now, University of Minnesota engineering researchers have developed a chip on which both sound wave and light wave are generated and confined together so that the sound can very efficiently control the light. The novel device platform could improve wireless communications systems using optical fibers and ultimately be used for computation using quantum physics.

The research was recently published in Nature Communications, a leading research journal.

The University of Minnesota chip is made with a silicon base coated with a layer of aluminum nitride that conducts an electric change. Applying alternating electrical signal to the material causes the material to deform periodically and generate sound waves that grow on its surface, similar to earthquake waves that grow from the epicenter of the earthquake. The technology has been widely used in cell phones and other wireless devices as microwave filters.

“Our breakthrough is to integrate optical circuits in the same layer of material with acoustic devices in order to attain extreme strong interaction between light and sound waves,” said Mo Li, assistant professor in the Department of Electrical and Computer Engineering and the lead researcher of the study.

The researchers used the state-of-the-art nanofabrication technology to make arrays of electrode with a width of only 100 nanometers (.00001 centimeters) to excite sound waves at an unprecedented high frequency that is higher than 10 GHz, the frequency used for satellite communications.

“What’s remarkable is that at this high frequency, the wavelength of the sound is even shorter than the wavelength of light. This is achieved for the first time on a chip,” said Semere Tadesse, a graduate student in the University of Minnesota’s School of Physics and Astronomy and the first author of the paper. “In this unprecedented regime, sound can interact with light most efficiently to achieve high-speed modulation.”

In addition to applications in communications, researchers are pursuing quantum physics applications for the novel device. They are investigating the interaction between single photons (the fundamental quantum unit of light) and single phonons (the fundamental quantum unit of sound). The researcher plan to use sound waves as the information carriers for quantum computing.

The research is funded by National Science Foundation and Air Force Office of Scientific Research. The device was fabricated in the cleanroom at the Minnesota Nano Center at the University of Minnesota.

Imaging at a trillion frames per second:

Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion.

This technology may someday be used to build cameras that can look “around” corners or see inside the body without X-rays.

Photography is about creating images by recording light. At the MIT media lab, professor Ramesh Raskar and his team members have invented a camera that can photograph light itself as it moves at, well, the speed of light.

New quantum test claims that the Heisenberg Uncertainty principle not quite right

(Source: Phys. Rev. Letter. and BBC News)

The Heisenberg uncertainty principle is in part an embodiment of the idea that in the quantum world, the mere act of observing an event changes it. But the idea had never been put to the test, and a team writing in Physical Review Letters (PRL 109, 100404 (2012)) says "weak measurements" prove the rule was never quite right. That could play havoc with "uncrackable codes" of quantum cryptography.

Quantum mechanics has since its very inception raised a great many philosophical and metaphysical debates about the nature of nature itself. Heisenberg's uncertainty principle, as it came to be known later, started as an assertion that when trying to measure one aspect of a particle precisely, say its position, experimenters would necessarily "blur out" the precision in its speed.

That raised the spectre of a physical world whose nature was, beyond some fundamental level, unknowable.
