Quantum chaos and regularity in theory
Helmut Kroeger, Xiang-Qian Luo, Harald Markum +1
We check the eigenvalue spectrum of the Hamiltonian against Poisson or Wigner behavior predicted from random matrix theory. We discuss random matrix theory as a tool…

Quantum Theory with Many Degrees of Freedom from Monte Carlo Hamiltonian
Xiang-Qian Luo, C. Q. Huang, J. Q. Jiang +3
With our recently proposed effective Hamiltonian via Monte Carlo, we are able to compute low energy physics of quantum systems. The advantage is that we can obtain not only the spe…
