They PhDid It! (Part 5): Dr Gan and Spintronics

They PhDid It! (Part 5): Dr Gan and Spintronics

Every year in CoS, dozens of PhD students defend their thesis and earn their doctorate, the highest university degree. In this series, we catch up with some new doctors to find out about their experience of doing a PhD in CoS, what made them embark on the intense four year journey and what plans they have for the future. Meet Dr Gan Weiliang, a research fellow from SPMS.

Building A Michelson Interferometer

Building A Michelson Interferometer

The Michelson interferometer is a device that uses optical intereference to measure extremely small distance variations. First invented in the late 19th century, it remains in active use today; in 2017,  the Nobel Prize in Physics was awarded to the LIGO experiment for using large-scale Michelson interferometers to detect gravitational waves. Recently, our team at SPMS set out to construct a Michelson interferometer for science education and outreach.

Probing the Ultimate Limits of Quantum Detection

Probing the Ultimate Limits of Quantum Detection

Suppose you only have enough energy to produce a dozen photons — what can you use them to see? In a new theoretical paper, the ultimate detection limits imposed by the laws of quantum physics have been derived, solving a decade-old open problem in quantum theory.

Discovery of a Two-Dimensional Carborane Cluster

Discovery of a Two-Dimensional Carborane Cluster

A new form of carborane, a cluster of carbon and boron atoms arranged in an unusual flat pattern, has been isolated by chemists at Nanyang Technological University, Singapore. This discovery has overturned a 50-year old set of theoretical rules central to cluster chemistry, paving the way to a new family of chemicals.

Physicists Create a Four Dimensional Synthetic Material

Physicists Create a Four Dimensional Synthetic Material

As we all know, space is three dimensional. Many aspects of physics, including the fundamental properties of matter, depend strongly on the dimensionality of space. For instance, 2D materials like graphene, in which the atoms are confined to a two dimensional plane, have properties very different from standard 3D materials. Now, researchers have created a synthetic material that behaves as though it has four dimensions (4D), higher than the number of dimensions in the space around us.
