Now in a new study, physicists Dr. Raditya Weda Bomantara and Professor Gong Jiangbin have theoretically demonstrated that different edge modes of a topological time crystal can be braided and that it is possible to exploit their approach to generate the states necessary for universal quantum computation.
Associate Professor Murray Barrett who led the research at NUS have discovered that lutetium - a previously overlooked element - possesses properties ideal for making high performance atomic clocks.
A team led by Prof Goki EDA from the Departments of Physics and Chemistry and the Centre for Advanced 2D Materials (CA2DM) at NUS has discovered a way to grow nano- and micro-ribbon structures of molybdenum disulphide that are only three atoms thick and on average hundreds of nanometers wide.
Thousands of years ago the Archimedes screw emerged as a superb design to pump water into irrigation ditches. It is believed to be of critical historical importance to the ancient world. On the physics side, in 1983 D.J. Thouless (Physics Nobel Laureate 2016) proposed an elegant quantum pump , which directly connects topological invariants with quantized matter transport. Thouless pump has opened up new applications of quantum physics and continues to influence fundamental research.
NUS physicists have found that complex electron-electron interactions change the energy levels at molecule-metal interfaces, affecting the performance of molecular electronic devices.
NUS physicists have developed new self-directed molecular motors for nanoscale applications.
NUS scientists have developed energy efficient ultra-thin light-emitting diodes (LEDs) for next generation communication technologies.

CQT researchers have exploited the vibrations of trapped ions to explore a phenomenon known from optics. The technique offers new tools for experiments in quantum thermodynamics and quantum computing.
NUS physicists have discovered that gold nanoparticles can enhance the light emission from tungsten disulphide (WS2) flakes and reveal minute changes in the material composition.
In two separate studies led by Professor Andrew Wee and Associate Professor Andrivo Rusydi from the Department of Physics at the NUS Faculty of Science, the researchers uncovered the role of oxygen in MoS2, and a novel technique to create multiple tunable, inverted optical band gaps in the material.
The Laser Brillouin group of Prof KUOK Meng Hau has simulated the dependence of the eigenmodes of skyrmions in ultrathin ferromagnetic films, on the Dzyaloshinskii-Moriya interaction and applied magnetic field. Special thanks to AIP, the work has been highlighted as an article in American Institute of Physics Publishing in the News, and as a press release in Newswise, entitled "The Synchronized Dance of Skyrmion Spins".
Prof ZHANG Chun and his Ph.D. student, LIU Shuanglong together with research fellow, Dr Argo NURBAWONO, from the Department of Physics, NUS have developed a more general version of the popular and widely-used density functional theory (DFT) which can be applied to steady-state non-equilibrium situations. Prof Zhang Chun's work has received attention by Phy.org
A collaboration between Prof Su Ying QUEK from the Department of Physics, NUS and Prof John THONG from the Department of Electrical and Computer Engineering, NUS has shown that "edge-contacted" device geometries in Ni/Co-graphene interfaces result in some of the lowest contact resistances reported to date.
NUS scientists in collaboration with BASF SE scientists have jointly developed a novel device structure for organic field-effect transistors (OFETs) that show unprecedentedly low contact resistance.
NUS physicists, Prof Jeroen Anton VAN KAN and his collaborators have designed and successively micro-fabricated a miniature ion beam source prototype, paving the way to improve ion beam brightness by up to a million times.
NUS physicists, Prof Edward Teo and Dr Chen Yu have found a new type of black hole that can exist in anti-de Sitter space, whose event horizon is infinite in extent yet has a finite area.
