Partition function zeros of quantum many-body systems: perturbative results
Muhammad Sedik, B Sriram Shastry
A systematic method to find the Yang-Lee partition function zeros of quantum many-body systems based on perturbation theory at finite temperatures was recently introduced in arXiv:…
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…
A Sum Rule for Thermal Conductivity and Dynamical Thermal Transport Coefficients in Condensed Matter -I
B Sriram Shastry
We display an interesting sum rule for the dynamical thermal conductivity for many standard models of condensed matter in terms of the expectation of a thermal operator. We present…
Extracting Hidden Symmetry from the Energy Spectrum
Emil A. Yuzbashyan, William Happer, Boris L. Altshuler +1
In this paper we revisit the problem of finding hidden symmetries in quantum mechanical systems. Our interest in this problem was renewed by nontrivial degeneracies of a simple spi…
