Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 23.05 в 11:30 будет заслушан
доклад:

Харинцев С. С. (Институт физики, Казанский федеральный университет)
Нелокальная фотоника разупорядоченных сред

Нелокальная фотоника - это новое научное направление, которое изучает
взаимодействие света со средами, обладающими сильной пространственной
дисперсией. Учет пространственной дисперсии (или пространственной
нелокальности) приводит к существенно новым физическим принципам
взаимодействия света и вещества. В частности, в нелокальных средах
возникают непрямые оптические переходы, обусловленные пространственным
синхронизмом электронов и фотонов, локализованных вблизи структурных
неоднородностей. В основе данного явления лежит увеличение импульса
фотонов при их пространственной локализации.

Примером нелокальных сред являются двойные системы «кристалл-жидкость»,
структура которых обладает дальним порядком и локальным беспорядком. К
таким системам относятся галоидные перовскиты, жидкие кристаллы,
коллоидные системы, высокоэнтропийные кристаллы, полимеры, вода,
мицеллы, белки и т.д. [1, 2].

В докладе будут рассмотрены такие полупроводники как кремний [3] и
металл-галоидные перовскиты [4], в которых наблюдается широкополосное
неупругое рассеяния света, известного как электронное комбинационное
рассеяние света [1-3]. Будет показано, что электронное рассеяние света
вызывает аномальное увеличение показателя преломления гетерогенных сред
и приводит к их оптическому нагреву. В лекции будут рассмотрены
некоторые приложения в области оптоэлектроники, фотовольтаики и
биомедицины.

Space Force general selected for Golden Dome program

U.S. President Donald Trump unveiled a plan for his ambitious "Golden Dome" missile defense shield this week, stating it will cost $175 billion and take about three years to develop - but some experts say the price tag could be many times higher.

NASA legend Gene Kranz returns to mission control

Gene Kranz, who served in Apollo mission control as "White Flight," was at the head of the room when Apollo 11 landed on the moon and Apollo 13 "had a problem." He may have never said "Failure is not an option," but his record of success has earned him a prestigious award.

Spaceflight

(Axiom Space)

Private Ax-4 mission to the ISS is 'go' for launch June 8

The next private astronaut mission to the International Space Station (ISS) just completed a major milestone ahead of its upcoming launch. Houston-based company Axiom Space completed an internal Flight Readiness Review (FRR) on Wednesday (May 21) ahead of the launch of the company's fourth crewed mission to the ISS. Ax-4 is on track for a liftoff next month on a SpaceX Falcon 9 rocket with a multinational crew aboard a brand-new Dragon spacecraft. The mission is scheduled to get off the ground on June 8 at 9:11 a.m. EDT (1311 GMT), from NASA's Kennedy Space Center in Florida.

Tile-shedding private Chinese rocket launches 6 satellites

The Chinese company LandSpace launched its methane-powered Zhugque-2E rocket on Saturday (May 17), carrying a batch of six satellites to orbit. Zhugque-2E lifted off Saturday at 12:12 a.m. EDT (0412 GMT; 12:12 p.m. in Beijing) from Site 96 at the Jiuquan Satellite Launch Center's Complex-43, in northwestern China's Gobi Desert. The mission, carried out by LandSpace for commercial satellite maker Changsha Tianyi Space Science and Technology Research Institute, known as Spacety for short, carried six Tianyi satellites into low Earth orbit (LEO).

Jupiter used to be twice as big as it is now

Long before it became the giant planet we see today, Jupiter was even bigger and had a much stronger magnetic field, according to a new study that looked back in time to reveal what the world was like in its early years.

Technology

(Starfish Space)

Starfish Space satellite will attempt 1st commercial docking

Starfish Space plans to make history on its second-ever mission, which is set to lift off next month. On Tuesday (May 20), the Seattle-based startup unveiled the outline of the groundbreaking flight, which is called Otter Pup 2. It will send one of Starfish's small Otter satellite-servicing vehicles to low Earth orbit (LEO) on SpaceX's Transporter 14 mission, which is scheduled to lift off in June.

Search for Life

Perseverance rover rolls into 'Crocodile' plateau on Mars

NASA's Perseverance rover has made to a new region on Mars, which may contain some of the Red Planet's oldest and most interesting rocks. Perseverance landed inside the 28-mile-wide (45 kilometers) Jezero Crater in February 2021, on a mission to search for past signs of Mars life and collect dozens of samples for future return to Earth.

Star Wars

(ILM/Lucasfilm)

'Star Wars: The Empire Strikes Back' at 45: Stop-motion master Phil Tippett on creating the iconic Battle of Hoth

Today marks the 45th anniversary of "Star Wars: The Empire Strikes Back," which was released in theaters by 20th Century Fox on May 21, 1980, and has been aptly christened by adoring fans and sagacious critics as one of the greatest sci-fi sequels ever made. Two-time Academy Award-winning visual effects wizard Phil Tippett ("Return of the Jedi," "Jurassic Park," "Starship Troopers") and his talented ILM team shot the movie's pivotal stop-motion sequences in Lucasfilm's warehouse headquarters in San Rafael, California. These iconic scenes transported audiences to the icy world of Hoth for the rebel base opening's camel-like tauntauns and menacing Imperial AT-AT Walkers.

100th woman in space talks inspiring the next generation

For Emily Calandrelli, known to many as "The Space Gal," the dream of spaceflight began over 20 years ago. Last year, that dream became a reality. As the 100th woman to travel to space, Calandrelli isn't just celebrating personal achievement -- she's using her journey to inspire others, uplift underrepresented communities and push the boundaries of STEM (science, technology, engineering and math) accessibility.

Asteroid passing between Earth and moon today

A newly discovered house-size asteroid is set to make a close, yet harmless approach to Earth today (May 21), passing within one-third of the Earth-moon distance. The close approach will happen at approximately 1:30 p.m. ET on May 21 (1730 GMT), at which point the asteroid, designated 2025 KF, will pass a mere 71,700 miles (115,000 kilometers) from Earth, according to NASA.

Are we ready for the worst space weather? 'We don't know'

Imagine being told a storm is heading your way, but you won't know how bad the winds are or whether they'll knock out power until just minutes before it hits. That's the challenge scientists face when it comes to predicting solar storms. We've come a long way in understanding space weather. We can spot solar storm eruptions, track their speed, and estimate when they'll arrive at Earth, sometimes with up to a day's warning. However, one critical piece of information remains frustratingly out of reach until the last moment: the orientation of the storm's magnetic field, known as the Bz component.

Early universe 'zippers' and 'twisters' may solve mystery

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe. Every major galaxy like the Milky Way has a retinue of smaller dwarf galaxies orbiting it. The Milky Way has several dozen, including the famous Large and Small Magellanic clouds. Beginning in the 1970s, astronomers noticed that these dwarf galaxies' positions and orbits weren't entirely random. Instead, dwarf galaxies tended to exist within the same plane. For example, the 11 brightest satellites of the Milky Way share a plane, and many dwarf galaxies around the Andromeda galaxy form what is known as the Great Plane of Andromeda.

A brand-new SpaceX rocket just earned its wings. A Falcon 9 rocket lifted off from Florida's Cape Canaveral Space Force Station Tuesday (May 20) at 11:19 p.m. EDT (0319 GMT on May 21), carrying 23 of the company's Starlink broadband satellites to low Earth orbit (LEO).

NASA's X-59 jet takes 'flight' without leaving the ground

During the testing, engineers turned on most of the aircraft's systems but left the engine off. The flight computer still had control over the X-59's control surfaces, responding to inputs that simulated changes in altitude, speed, temperature or the health of its various systems.
