Escaping the quantum critical singularity; modulated magnetism in PrPtAI
The transition between ferromagnetism and paramagnetism in metals is one of the simplest examples of a continuous phase transition. Interesting behaviour is expected when the transition temperature becomes small because incoherent fluctuations above the transition...
A light touch to reading electron spins
Scientists at the LCN have shown a new way of reading electron spins, which eliminates the need for powerful magnetic fields and reduces the reliance on very low temperatures. The study is published this week in the journal Nature Materials. One of the fundamental...
Quantum states explored with a voltmeter
Research has demonstrated laser control of quantum states in an ordinary silicon wafer and observation of these states via a conventional electrical measurement. The findings – published in the journal Nature Communications by a UK-Dutch-Swiss team from the...
