How to detect weak emergent broken-symmetries of the Kagome antiferromagnet from Raman spectroscopy
O. Cepas, J. O. Haerter, C. Lhuillier
We show that the magnetic Raman response of a spin-liquid is independent of the polarizations of the light for triangular symmetries. In contrast, a ground-state that has a broken…
The Hall Number, Optical Sum Rule and Carrier Density for the -- model
Jan O. Haerter, B. Sriram Shastry
We revisit the relationship between three classical measures of particle number, namely the chemical doping , the Hall number and the particle number inferred from th…
Dynamical thermal response functions for strongly correlated one-dimensional systems
Michael R. Peterson, Subroto Mukerjee, B. Sriram Shastry +1
In this article we study the thermal response functions for two one-dimensional models, namely the Hubbard and spin-less fermion - models. By exactly diagonalizing finite siz…
Thermoelectric effects in a strongly correlated model for NaCoO
Michael R. Peterson, B. Sriram Shastry, Jan O. Haerter
Thermal response functions of strongly correlated electron systems are of appreciable interest to the larger scientific community both theoretically and technologically. Here we fo…
Finite temperature properties of the triangular lattice t-J model, applications to NaCoO
Jan O. Haerter, Michael R. Peterson, B. Sriram Shastry
We present a finite temperature () study of the t-J model on the two-dimensional triangular lattice for the negative hopping , as relevant for the electron-doped NaCoO$_2…
Strong Correlations Produce the Curie-Weiss Phase of NaCoO
Jan O. Haerter, Michael R. Peterson, B. Sriram Shastry
Within the t-J model we study several experimentally accessible properties of the 2D-triangular lattice system NaCoO, using a numerically exact canonical ensemble study of…
Kinetic Antiferromagnetism in the Triangular Lattice
Jan O Haerter, B Sriram Shastry
We show that the motion of a single hole in the infinite Hubbard model with frustrated hopping leads to weak metallic antiferromagnetism of kinetic origin. An intimate relation…
