Quantum mechanics


Quantum mechanics is the study of the dynamics of particles at its most fundamental level. The state of a particle, such as its position or momentum, is described by a statistical distribution given by its wavefunction. As this name suggests, this formalism gives matter many properties that are classically associated with waves.

    Physicists have discovered a new topological phase of matter, the Weyl semimetal, whose surface features a non-closed Fermi surface whereas the low-energy quasiparticles in the bulk emerge as Weyl fermions. A brief review of these developments and perspectives on the next steps forward are presented.

    Topological semimetals give access to new quantum phenomena — for example, massless fermions have not been observed as elementary particles, yet they can be realized in the form of quasiparticles in these materials — and could allow the development of robust quantum devices.
