Sweeping of Lattice Disorder and Associated Phenomena in Colossal Magnetoresistance Compounds
Evgenii E. Narimanov, Chandra M. Varma
We show through a variational calculation that in a large range of parameters the paramagnetic to ferromagnetic transition in colossal magnetoresistance compounds is accompanied by…
Higgs Boson in Superconductors
C. M. Varma
Superfluid helium, describable by a two-component order parameter, exhibits only the Bogolubov mode with energy at long wavelengths, while a Lorentz-invariant theory with a…
Singular Fermi Liquids
C. M. Varma, Z. Nussinov, W. van Saarloos
An introductory survey of the theoretical ideas and calculations and the experimental results which depart from Landau Fermi-liquids is presented. Common themes and possible routes…
Ferroelectrics with Low-energy Electronic Excitations
T. K. Ng, C. M. Varma
We formulate a general theory of the dielectric response of a lattice with a structural transition and a polarization instability due to a soft-optic mode coupled to low energy ele…
