His Leiden honorary doctorate, the future of scientists, and diversity in science. Robbert Dijkgraaf tells about it in one of the classical rooms of the Academy Building. ‘It's very special, my honorary doctorate. A rare homage.’

Majorana particles have been getting bad publicity: a claimed discovery in ultracold nanowires had to be retracted. Now Leiden physicists open up a new door to detecting Majoranas in a different experimental system, the Fu-Kane heterostructure, they announce in Physical Review Letters.

Measurements on a superconducting material show an abrupt transition between a normal metal and a 'strange' metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. 'We don't have any theoretical machinery for this', says theoretical physicist Jan Zaanen,…

For the first time, physicists have visualized the ‘melting’ of electrons inside a special class of insulators. It allows electrons to move freely and turns the insulator into a metal and possibly later into a superconductor. Publication in Nature Physics.

Irene Battisti is the discoverer of the year 2019. The physicist won the C.J. Kok Public Award for her research into microscopy and superconductors.
