Research paper published in Nature Physics

Prof. Scarani’s new research paper published in Nature Physics: Quantum non-locality based on finite-speed causal influences leads to superluminal signalling. An experiment has been proposed that could make us to make a choice between extremes to describe the behavior of the Universe. It is based on what the researchers call a 'hidden influence inequality' exposing how quantum predictions challenge our best understanding about the nature of space and time, Einstein's theory of relativity.

PROVOST'S and DEAN'S CHAIRS

These Chair Professorships are for a three-year term with effect from 1 July 2012, and are bestowed in recognition of their excellent academic contributions to the Faculty and international recognition in their fields of research.

Provost's Chair : Professor Valerio Scarani
Professor Scarani did seminal work on quantum cryptography. He invented a new protocol for more robustly distributing secret messages between distant partners using laser sources. His works on device-independent quantum cryptography and "information causality" are hugely influential and has earned him an international reputation.

Dean's Chairs : Associate Professor Peter Ho
Assoc Prof Ho has made outstanding contributions to the fundamental physics and solution to technological issues of organic semi-conductor devices, such as light-emitting diodes, field-effect transistors, and solar cells. Leading the Organic Nano Device Laboratory (NUS), he and his team has made a number of recent breakthroughs and innovations such as robust polymer-nanometal composites with composition-tuneable conductivity, or novel high-performance polymer semiconductor heterostructures for light-emitting diodes and photovoltaic applications.


Quantized Adiabatic Transport In Momentum Space

A/P Gong Jiangbin's most recent publication with his student, Derek Ho was highlighted as "Editor's Suggestion" by PRL Derek Y. H. Ho and Jiangbin Gong, Quantized Adiabatic Transport In Momentum Space, Phys. Rev. Lett. 109, 010601 (2012). Though topological aspects of energy bands are known to play a key role in quantum transport in solid-state systems, the implications of Floquet band topology for transport in momentum space (i.e., acceleration) have not been explored so far. Using a ratchet accelerator model inspired by existing cold-atom experiments, here we characterize a class of extended Floquet bands of one-dimensional driven quantum systems by Chern numbers, reveal topological phase transitions therein, and theoretically predict the quantization of adiabatic transport in momentum space. Numerical results confirm our theory and indicate the feasibility of experimental studies.


Novel findings on a universal gene-silencing nucleoprotein structure in bacterial

Recent research led by Aassociate Professor Yan Jie at the department of physics and principal investigator at MBI (Mechanobiology Institute), NUS, reported that the E. coli H-NS and its paralogue StpA form rigid helical nucleoprotein filaments on DNA.

Unveiling the Mystery of DNA overstretching transitions

In a series of publications, Assoc/Prof Yan Jie and his team recently made several significant breakthroughs in resolving this debate, confirming the existence of S-DNA. They demonstrated that the overstretching transition produces both types of structural reorganization, depending on minor changes in the physiological environmental conditions. The PNAS paper was published online.


Quantum Information Motion Control Is Now Improved

It was reported that a team of physicists from the Centre for Computational Science and Engineering of the NUS Faculty of Science and China's Zhejiang University have devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. The study could have implications for quantum computers due to improvements in the transport of discrete amounts of information, known as qubits, that are encoded in electrons. It was also mentioned that their paper is about to be published in The European Physical Journal B. A similar report was carried in Physorg.com Online (3 April 2012).

The Rubicon programme is a research programme funded by both Netherlands Organisation for Scientific Research (NWO) and EU Marie Curie Actions. It is directed at promising young postdoctoral researchers who are still at the start of their careers but whose academic strengths give them the potential to become established figures in the Dutch research world. The Rubicon programme is open to all scientific disciplines, e.g. language, culture, science and law, and all nationalities. It offers researchers the opportunity to gain knowledge, skills and experience by spending up to 2 years at a top research institute outside the Netherlands. There is also a limited opportunity to apply for a research period at an excellent Dutch research institute.
