Partition function zeros of quantum many-body systems
B Sriram Shastry
We present a new method for calculating the Yang-Lee partition function zeros of a translationally invariant model of lattice fermions, exemplified by the Hubbard model. The method…
The Integrable system: The Universal Hamiltonian for Quantum Chaos
B. Sriram Shastry
We summarize recent work showing that the model of interacting particles in 1-dimension is a universal Hamiltonian for quantum chaotic systems. The problem is analyzed in t…
Super Lax Pairs and Infinite Symmetries in The System
B. Sriram Shastry, Bill Sutherland
We present an algebraic structure that provides an interesting and novel link between supersymmetry and quantum integrability. This structure underlies two classes of models that a…
Method for reconstructing the self-energy from the spectral function
B Sriram Shastry
A fundamental question about the nature of quantum materials such as High-T systems remain open to date -- it is unclear whether they are (some variety of) Fermi liquids, or (s…
