This observation constitutes a concrete example of a three-dimensional quantum spin liquid—a topical state of ... be achieved in a number of ways that grow exponentially with the number of tetrahedra involved, so that no order can occur. A spin ice is ...

The integral membrane protein MsbA (blue) embedded in a ‘semi-transparent’ membranous nanodisc (grey). The nanodisc itself is, through selective deuteration, rendered invisible in SANS experiments that ... in its native context. The membranes that surround our cells contain a large number of proteins. Membrane proteins are therefore a crucial class ...
