Topological order and thermal equilibrium in polariton condensates
In a two-dimensional fluid, disorder-causing mechanisms are exceptionally strong and so an absolute order cannot be achieved. Nevertheless, there is an enormous difference between systems of lesser and of greater order (for example between an ordinary fluid such as...
Turning a pinch of salt into an electrical switch
A team of scientists from the LCN at UCL, the University of Liverpool in the UK and the Advanced Microscopy Laboratory at the University of Zaragoza in Spain have discovered a way to induce and control a fundamental electrical switching behaviour by interfacing...
Fixing the positions of individual molecules on the surface of a single layer of silicon atoms
A new way to control the positioning of individual molecules on the surface of materials that are only a single layer of atoms thick has been discovered by a team of scientists from the LCN at UCL in the UK; the Japan Advanced Institute of Science and Technology...
Observation of strong coupling and cavity quantum electrodynamics in a solid-state MASER at room-temperature
Creating practical solid-state, quantum computers that operate at room-temperature is a challenging task. This is because stored information is readily destroyed by thermal noise. A signature of a physical system’s ability to function as a quantum computer is the...
