Researchers Discover A New Property Of Light



An international team of researchers have discovered a new property of light called “self-torque”


First, let’s take a step back. Over the last few decades, physicists have discovered that it is possible to twist the wavefront of a light beam, giving it angular momentum. This looks a bit like a spiral staircase, with the beam wrapping around an empty middle. When such a beam is targeted at something, you see a bright donut. These beams are said to have orbital angular momentum (OAM), a property not dependent on polarization (which instead is about the geometry of the electromagnetic oscillations.)
As reported in the latest issue of the journal Science, researchers have discovered that it’s possible for an OAM light beam to exhibit “self-torque”. As the beam moves forward, its twist goes from wider to narrower, a bit like a screw. If such a beam is projected onto a flat surface, it would appear in the shape of a croissant or crescent.
“Remarkably, in addition to many well-known properties such as intensity, wavelength, and polarization, light can be twisted and thus it can possess angular momentum,” co-author Carlos Hernandez-garcia, a senior researcher at the University of Salamanca, said in a video released with the paper.


The discovery happened when the team was studying light beams produced in certain high-energy optical processes. These are often used to generate extreme ultraviolet light or powerful X-rays in order to study tiny and fast molecular processes. The team discovered that self-torque light beams are a natural product of these processes.
“I remember when the Salamanca team first told us about the self-torque of light in this experiment, we really scratched our heads a lot about this,” said study author Kevin Dorney, a postdoctoral researcher associate at Kapteyn-Murnane Group, JILA. “Orbital angular momentum is not such a trivial subject to begin with, so when you add a time dependence into the profile of these beams, things get very interesting.”
“With self-torque, we take two visible donut beams, separate them by just a little bit in time and then make the harmonics with that. When we do that, the beam that is emitted actually looks like a croissant. And this croissant contains over an octave of orbital angular momentum values along the light pulse. And that’s the unique property of the self-torque of light,” Dorney added.




The team are now interested in studying how the beams behave and if there is any application to such a discovery.
“This is the first time that anyone has predicted or even observed this new property of light, so the immediate applications are not obvious,” co-lead author Laura Rego, of the University of Salamanca, said in the video. “From the fundamental-science point of view, this new structural property adds a new degree of freedom to study the dynamics of the light-matter interaction.”
One day, it might even be possible for researchers to develop a way to modulate this self-torque like we can modulate frequencies of other sorts.

  1. This new torque behavior of light might be a good quantum screw driver. Turning a gyro on that level could steer exotic reactions and guidance capabilities beyond anything ever before. An oscillating preferred chiral orientation would make a laser a drill with precise depth penetration. A colloidal could be stirred be for a new fabrication technique. I can think of many applications. Just no guarantee my conjecture is realistic.

Am so happy, thanks to Dr OLU I also learn that Dr OLU also help with Breast Enlargement Hips and Bums Enlargement etc.. If you are in any situation with a little Penis, weak ejaculation, small breast_hips_bums do get to Dr OLU now for help on his email (Drolusolutionhome@gmail.com) or add him on whatsapp line +2348140654426

  5. hello, I am becky morgan After being in relationship with Anderson for years, he broke up with me, I did everything possible to bring him back but all was in vain, I wanted him back so much because of the love I have for him, I begged him with everything, I made promises but he refused. I explained my problem to my friend and she suggested that I should rather contact a spell caster that could help me cast a spell to bring him back but I am the type that never believed in spell, I had no choice than to try it, I mailed the spell caster, and he told me there was no problem that everything will be okay before three days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4 pm. My ex called me, I was so surprised, I answered the call and all he said was that he was so sorry for everything that happened that he wanted me to return to him, that he loves me so much. I was so happy and went to him that was how we started living together happily again. Since then, I have made promise that anybody I know that have a relationship problem, I would be of help to such person by referring him or her to the only real and powerful spell caster who helped me with my own problem. email: {drgodfathercure@gmail.com or what's app +2347062606817} you can email him if you need his assistance in your relationship or any other Case.

  9. I’m indeed very happy for the great help that Dr. ebhodaghe rendered to me, I am here to give my testimony about a doctor who helped me in my life. I and my wife was infected with HERPES SIMPLEX VIRUS last 4 years ago, we went to many hospitals for cure but there was no solution, on till one faithful day , we saw a blog whereby Dr. ebhodaghe cured a woman who also had herpes affection,we (Me and My wife) decided to contact him which we did, he asked us to buy some items, unfailingly we sent him the money he will need in buying the items required , He caste the spell and sent me some herbs. He asked me to go for check-up after 17 days of casting the spell, Luckily for me we were tested herpes negative, now I believe all these Testimonies about him on the internet, he is truly a great man, if you are going through the same problem and you need help you can contact the great Herbalist (drebhodaghe7@gmail.com) or call/ WhatsApp +2347063500456

  10. I want to share a testimony of how Dr.Osemuhau herbal mixture cream saves me from shame and disgrace, my penis was a big problem to me as the size was really so embarrassing,and i was also having weak erection problem. I can't make love to my wife and my penis was just too small a full grown man like me having 4 inches penis and to worsen it i don't last in sex i cant even last two minutes it was really a thing of shame to me. My wife was really tired of me because my sex life was very poor,she never enjoyed sex,i was always thinking and searching for solutions everywhere until when i saw a testimony of how Dr.Osemuhau herbal mixture cream have been helping people regarding their sex life, so i decided to give him a try and to my greatest surprise in less than one week of taking the herbs my penis grow to 8 inches i couldn't believe my eyes and as i speak now my penis is now 8 inches and i do not have week erection again. I can make love to my wife longer in bed. And my marriage is now stable,my wife now enjoy me very well in bed. can contact him drosemuhau@gmail.com {) or call or what-apps him through +2348168714427
