Why some wet surfaces are less slippery
Why some wet surfaces are less slippery
Many surfaces get slippery when wet. Some surfaces have the opposite behaviour: they get less slippery. UvA researchers have now shed light on why this is the case. Hydrogen bonds between the surface and the water turn out to play an important role. The research, carried out by PhD candidate Liang Peng in collaboration with five physicists and chemists from UvA, ARCNL and the German Max Planck Institute for Polymer Research, was published in Physical Review Letters this week.

Photonic chip with record-breaking radio frequency dynamic range
Researchers at the University of Twente have developed a revolutionary programmable integrated microwave photonic filter with a record-breaking dynamic range. This represents a major breakthrough in the integration of functionality and performance in radio frequency photonic signal processors. David Marpaung, one of the authors of the study says: "Our work breaks the conventional and fragmented approach of integration, functionality and performance that currently prevents the adoption of these photonic systems in real applications.

Quantum sound connects future quantum devices
Physicists from the Gröblacher lab at TU Delft have built a device that can link different quantum devices and qubits to each other. This device, a silicon chip with vibrations traveling through it, functions as a network between quantum devices. This marks the first time that scientists are able to store as many qubits as they'd like within a very compact area on this type of chip.

Building the backbone of the information society
Building the backbone of the information society
How the Eindhoven Hendrik Casimir Institute develops novel information and communication systems. The future of our information-based society will be built on hybrid technologies, EHCI researchers Diana Leitao and Chigo Okonkwo are convinced. And that is why both scientists, though firmly rooted in their respective disciplines of physics and electrical engineering, are strong advocates for seeking synergies between people with different research backgrounds.

Confining classical and quantum waves with crystals
Manipulating elusive waves like light, sound or electrons, in periodic structures or crystals, has something mysterious. In the leading physics journal Physical Review Letters, published by the American Physical Society, a team of researchers from the University of Twente now describes how any kind of wave, whether quantum or classical, is confined in any kind of crystal.

Chains of liquid
Chains of liquid
Pour coffee into a mug and you might notice that the liquid cascading from the jug resembles droplets linked in a chain. Such oscillating "waterfalls" crop up frequently in our daily lives, but their origin is still not fully understood. In a publication that appeared in Physical Review Fluids this week, UvA-IoP physicist Antoine Deblais and coworkers shed light on these chains of liquid.

Trapping sound and light on a chip
Scientists at the University of Twente have developed a new technique to effectively trap soundwaves and light, using multilayer silicon nitride waveguides. The research project successfully proved that manipulating light with sound in large-scale circuits is viable and compatible with current production methods Expanding the photonic toolbox In recent decades, chips and electronic devices have become exponentially smaller and faster.

Astronomers detect hot gas bubble swirling around the Milky Way's supermassive black hole
Astronomers detect hot gas bubble swirling around the Milky Way’s supermassive black hole
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a 'hot spot' orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. The research was led by Maciek Wielgus of the Max Planck Institute for Radio Astronomy in Bonn, Germany.

Quantum algorithms help computers understand language
PhD candidate uses tools from quantum mechanics to help computers interpret ambiguous language. Words or sentences can often have multiple meanings. This is a concept that is hard to grasp for regular computers. PhD candidate Adriana Duarte Correia used quantum algorithms to make computers understand that a sentence like 'Look at the dog with one eye' can mean two different things at the same time.

Interplay of electronics and photonics for next generation quantum devices
Interplay of electronics and photonics for next generation quantum devices
For building quantum computers, making use of both electronics and photonics - technology that works with light - on one and the same chip, is promising. Thanks to silicon technology that we know well from today's electronic devices, quantum devices could be better protected from influences from the outside world.

Can we live longer? Leiden physicist makes discovery in protective layer in genes
Can we live longer? Leiden physicist makes discovery in protective layer in genes
With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery will help us understand ageing and disease.

TU Delft researchers create flow-driven rotors at the nanoscale
Researchers from TU Delft have constructed the smallest flow-driven motors in the world. Inspired by iconic Dutch windmills and biological motor proteins, they created a self-configuring flow-driven rotor from DNA that converts energy from an electrical or salt gradient into useful mechanical work. The results open new perspectives for engineering active robotics at the nanoscale.

Explosive neutron star merger captured for the first time in millimeter light
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)- an international observatory co-operated by the US National Science Foundation's National Radio Astronomy Observatory (NRAO)- have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star.

Quantum Machine Learning enters the fray in CERN’s LHCb experiment
In a recent article in the Journal of High Energy Physics (JHEP), the LHCb collaboration reports the application of Quantum Machine Learning for identifying properties of so-called jets: streams of particles that result from particle collisions. It is the first paper to describe the application of quantum computing to the identification of jets originating from beauty quarks or anti-quarks, a type of particle of particular interest to the LHCb experiment.

Magnetic spins that 'freeze' when heated: nature in the wrong direction
Magnetic spins that ’freeze’ when heated: nature in the wrong direction
Physicists observed a strange new type of behaviour in a magnetic material when it's heated up. The magnetic spins 'freeze' into a static pattern when the temperature rises, a phenomenon that normally occurs when the temperature decreases. They publish their findings in Nature Physics on July 4th. The researchers discovered the phenomenon in the material neodymium, an element that they described several years ago as a 'self-induced spin glass'.

Negligence in Nature article on Quantized Majorana conductance
In the 2018 Nature article Quantized Majorana conductance , the first author involved, Dr Hao Zhang, and corresponding author, Professor Leo Kouwenhoven, were partly negligent and partly culpably negligent. There was no violation of scientific integrity. This is the judgement of the Executive Board of TU Delft, based on recommendations of the TU Delft Research Integrity Committee (CWI), supported by external experts, and advice of the Netherlands Board on Research Integrity (LOWI).
