One laser is enough

Gases in the environment can be spectroscopically probed fast and precisely using so-called dual frequency combs. Researchers at ETH have now developed a method by which such frequency combs can be created much more simply and cheaply than before. Read more

Artificial magnetic fields for photons

Light particles do not usually react to magnetic fields. Researchers at ETH Zurich have now shown how photons can still be influenced by electric and magnetic fields. In the future that method could be used to create strong artificial magnetic fields for photons. Read more

Temperature sensor for artificial skin

The capacity to detect temperature changes is an important function of the human skin. Researchers at ETH Zurich have now developed a highly sensitive and, at the same time, flexible temperature sensor, which could soon be used in prosthetic limbs and robotic arms. Read more

Hot on the heels of quasiparticles

Electrons in a solid can team up to form so-called quasiparticles, which lead to new phenomena. Physicists at ETH in Zurich have now studied previously unidentified quasiparticles in a new class of atomically thin semiconductors. The researchers use their results to correct a prevailing misinterpretation. Read more

Metal in chains

The electronic energy states allowed by quantum mechanics determine whether a solid is an insulator or whether it conducts electric current as a metal. Researchers at ETH have now theoretically predicted a novel material whose energy states exhibit a hitherto unknown peculiarity. Read more

Electrons at the speed limit

Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Researchers at ETH Zurich have now investigated how fast electrons can ultimately be controlled with electric fields. Their insights are of importance for the petahertz electronics of the future.

First creation of huge quantum states with oscillating ions

For years physicists have strived to control the quantum states of atoms or molecules very accurately. Researchers at ETH Zurich have now established a record for the size of  quantum states generated with massive particles. Their technique could be used to make quantum computers faster. Read more

Three-way battles in the quantum world

In phase transitions, for instance between water and water vapour, the motional energy competes with the attractive energy between neighbouring molecules. Physicists at ETH Zurich have now studied quantum phase transitions in which distant particles also influence one another. Read more

Faster entanglement of distant quantum dots

Entanglement between distant quantum objects is an important ingredient for future information technologies. Researchers at the ETH have now developed a method with which such states can be created a thousand times faster than before. Read more

Surprising discovery of a new particle

Studying peculiar properties of a long known metallic material researchers have chanced upon a new particle. It is related to the so-called Weyl fermions that the mathematician Hermann Weyl predicted almost ninety years ago. Weyl had overlooked the particle, which could have interesting applications in electronics. Read more

A resonator for electrons

Resonators are an important tool in physics. The curved mirrors inside the resonators usually focus light waves that act, for instance, on atoms. Physicists at ETH Zurich have now managed to build a resonator for electrons and to direct the standing waves thus created onto an artificial atom. Read more

Smaller, faster, cheaper

Transmitting large amounts of data, such as those needed to keep the internet running, requires high-performance modulators that turn electric signals into light signals. Researchers at ETH Zurich have now developed a modulator that is a hundred times smaller than conventional models. Read more

Soundproofing with quantum physics

Sebastian Huber and his colleagues show that the road from abstract theory to practical applications needn’t always be very long. Their mechanical implementation of a quantum mechanical phenomenon could soon be used for soundproofing purposes. Read more

Squeezed quantum cats

ETH professor Jonathan Home and his colleagues reach deep into their bag of tricks to create so-called “squeezed Schrödinger cats”. These quantum systems could be extremely useful for future technologies. Read more
