Spontaneous exciton condensation in 1T-TiSe2: a BCS-like approach
C. Monney, H. Cercellier, F. Clerc +9
Recently strong evidence has been found in favor of a BCS-like condensation of excitons in 1\textit{T}-TiSe. Theoretical photoemission intensity maps have been generated by the…
Evidence for an excitonic insulator phase in 1T-TiSe
H. Cercellier, C. Monney, F. Clerc +7
We present a new high-resolution angle-resolved photoemission study of 1\textit{T}-TiSe in both, its room-temperature, normal phase and its low-temperature, charge-density wa…
Charge order and phase segregation in overdoped bilayer manganites
T. Maitra, A. Taraphder, H. Beck
There have been recent reports of charge ordering around in the bilayer manganites. At , there appears to be a coexistence region of layered A-type antiferromagnetc…
Effect of orbital currents on the restricted optical sum rule
L. Benfatto, S. G. Sharapov, H. Beck
We derive the restricted optical-conductivity sum rule for a model with circulating orbital currents. It is shown that an unusual coupling of the vector potential to the interactio…
Transport properties in the d-density-wave state in an external magnetic field: The Wiedemann-Franz law
S. G. Sharapov, V. P. Gusynin, H. Beck
We derive the electrical and thermal conductivities of the -density-wave state in an external magnetic field in the low-temperature regime and in the presence of impurities.…
