This it is the story of a unique material – made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle. It is also the story of three research groups – two at the Weizmann Institute of Science and one in Germany, and the unique bond that has formed between them.
The material belongs to a group of materials discovered a decade and a half ago known as topological insulators. These materials are conducting on their surfaces and insulating in their inside “bulk.” But the two properties are inseparable: Cut the material, and the new surface will be conducting, the bulk will remain insulating.

Is there life on Triton, the largest moon circling the planet Neptune? An Israeli project aims to find out. One of its key measurement tools will be a super-accurate clock that loses less than one second every 10 million years.
But first, the Israeli project – dubbed “Trident” after the Roman sea god Neptune’s three-pronged spear – must be chosen by NASA to head to space.
Trident, sponsored by the Weizmann Institute of Science and the Israel Space Agency, is one of four projects chosen out of 22 proposals. Each project will now receive $3 million. However, only two will make the final cut for launch in 2026. The craft is expected to reach Neptune in 2038.
Jun 22, 2020... In 2018 it was discovered that two layers of graphene twisted one with respect to the other by a “magic” angle show a variety of interesting quantum phases, including superconductivity, magnetism and insulating behaviours. Now a team of researchers from the Weizmann Institute of Science led by Prof. Shahal Ilani of the Condensed Matter Physics Department, in collaboration with Prof. Pablo Jarillo-Herrero’s group at MIT, have discovered that these quantum phases descend from a previously unknown high-energy “parent state,” with an unusual breaking of symmetry.

No sooner had the radical equations of quantum mechanics been discovered than physicists identified one of the strangest phenomena the theory allows.
“Quantum tunneling” shows how profoundly particles such as electrons differ from bigger things. Throw a ball at the wall and it bounces backward; let it roll to the bottom of a valley and it stays there. But a particle will occasionally hop through the wall. It has a chance of “slipping through the mountain and escaping from the valley,” as two physicists wrote in Nature in 1928, in one of the earliest descriptions of tunneling.
Jan 12, 2021... In this special session, Prof. Avishay Gal-Yam, Weizmann’s supernova hunter, takes us to the Frontiers of the Universe: one of the Institute’s new flagship projects. From studying the tiniest subatomic particles to the far reaches of the galaxy, this initiative aims to put the Institute at the very forefront of advanced physics research – and even into space.

Jan 19, 2021... We have been measuring time for millennia. Prof. Roee Ozeri of the Department of Physics of Complex Systems and Institute Vice President, provides an engaging history of these efforts, their inspiration, and their efficacy, from the sundial to the pendulum to modern atomic clocks.
Dec 29, 2020... Quantum mechanics, the theory that describes the physics of the universe at very small scales, is notorious for defying common sense. Consider, for instance, the way that standard interpretations of the theory suggest change occurs in the quantum turf: shifts from one state to another supposedly happen unpredictably and instantaneously. Put another way, if events in our familiar world unfolded similarly to those within atoms, we would expect to routinely see batter becoming a fully baked cake without passing through any intermediate steps. Everyday experience, of course, tells us this is not the case, but for the less accessible microscopic realm, the true nature of such “quantum jumps” has been a major unsolved problem in physics.
Jan 28, 2021... This webinar introduces Weizmann’s flagship Frontiers of the Universe initiative. Frontiers of the Universe will advance the Institute’s pioneering efforts to understand the nature of space, time, and life itself—from the tiniest subatomic particles to the largest galaxies.

REHOVOT, ISRAEL—January 12, 2021—In the not-so-distant past, the discovery of a supernova—or exploding star—was considered a rare occasion.
When Prof. Avishay Gal-Yam of the Weizmann Institute’s Particle Physics and Astrophysics Department was a doctoral student, he only located seven supernovas over the course of four years. But today, advanced measuring instruments and analytical methods make it possible to detect fifty such explosions daily. While these improved means may have made these celestial events somewhat less notable over the years, the greater number of observations has also increased the probability that researchers will spot rarer types of explosions that have so far existed only as theoretical constructs. Gal-Yam and his colleagues recently discovered a rare-type supernova that has never been observed before. Their findings are being published today in Nature.

A rock star, a Paralympic swimmer, and a Nobel Prize in Physics laureate were among the nine recipients of honorary Doctor of Philosophy degrees from the Weizmann Institute of Science on Monday, November 7, bestowed upon them in recognition of their extraordinary contributions to society.
"Each one of tonight’s honorees has expanded the limits of the possible, while inspiring others to fulfill their own boundless potential," Prof. Alon Chen, president of the Weizmann Institute, said at the conferment ceremony, hosted by news anchor Lucy Aharish on campus at the Michael Sela Auditorium. Part of the Institute’s 74th Annual General Meeting of the International Board, the ceremony and related events are taking place in person — and as usual — for the first time since the outbreak of the COVID-19 pandemic.
