Citation | Peter Littlewood has made seminal contributions in the theory of collective phenomena in condensed matter physics. While at Bell Laboratories, NJ, he developed the phenomenology of sliding charge density waves, as model systems for friction and force flow. In systems such as niobium triselenide he explained the coupled AC and DC phenomena, glassy dynamics, and self- organised criticality. He provided the accepted mechanism for colossal magnetoresistance in manganese oxides, and this work has been very influential. He discovered the amplitude collective mode in superconductors, which is the condensed matter analogue of the Higgs boson, and he invented the marginal Fermi liquid phenomenology for cuprate superconductors. His recent work in Cambridge is centred around Bose condensation and lasing in semiconductor microstructures. |
