Fluctuating spin density waves in metals
Recent work has used a U(1) gauge theory to describe the physics of Fermi pockets in the presence of fluctuating spin density wave order. We generalize this theory to an arbitrary band structure and ordering wavevector. The transition to the large Fermi surface state, without pockets induced by local spin density wave order, is described by embedding the U(1) gauge theory in a SU(2) gauge theor...
متن کاملFluctuating charge-density waves in a cuprate superconductor.
Cuprate materials hosting high-temperature superconductivity (HTS) also exhibit various forms of charge and spin ordering whose significance is not fully understood. So far, static charge-density waves (CDWs) have been detected by diffraction probes only at particular doping levels or in an applied external field . However, dynamic CDWs may also be present more broadly and their detection, char...
متن کاملSuperconductivity and spin-density waves in multiband metals
We present a detailed description of two-band quasi-two-dimensional metals with s-wave superconducting SC and antiferromagnetic spin-density-wave SDW correlations. We present a general approach and use it to investigate the influence of the difference between the shapes and the areas of the two Fermi surfaces on the phase diagram. In particular, we determine the conditions for the coexistence o...
متن کاملUniversal thermopower of bad metals
“Bad metals” are known to have a large linear resistivity at highT that is universally seen near the Mott-Hubbard insulating phase. Less well known is that the thermopower α(T ) of the Mott-Hubbard systems also exhibits simple universal features: (i) close to the insulating phase, where the resistivity has a low-temperature upturn, α(T ) has a pronounced low-T peak that shifts to higher T with ...

of the S, state in place of the second C, value in eq 9. Note that the first C, value must be that of the So state since the distribution of the CF3H molecule is the same as that in the ground state duing the light absorption. In this way, the stabilization energy in the SI state during the light absorption is calculated to be 904 cm-]. With these values, the bathochromic shift due to the compl...
