Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A quantum of energy in a crystal lattice or other system of bodies which has momentum and position and can in some respects be regarded as a particle.
- ‘At this point we no longer discuss electrons but quasiparticles.’
- ‘The effective masses of the electrons are therefore increased - by a few percent in simple metals and by factors of up to 1000 in ‘heavy fermion ‘systems - but the quasiparticles still carry the same charge and spin as free electrons.’’
- ‘Remember that we also know that in many body systems there are quasiparticles which act very much like normal particles.’
- ‘One point which Wen is particularly excited about is that fermions can appear as quasiparticles in local bosonic lattice systems.’
- ‘There are two types of quasiparticles, Bose and Fermi, and physicists around the globe are exploring the properties of each type.’
