Complexity of the Laughlin wave function from the Dyson-orbital perspective
J. M. Zhang, Y. Liu
The Fermi sea is a simple and common concept in physics. However, a related and equally simple concept -- the Dyson orbital -- is far less discussed in physics, especially in textb…
Hartree-Fock approximation for bosons with symmetry-adapted variational wave functions
B. R. Que, J. M. Zhang, H. F. Song +1
The Hartree-Fock approximation for bosons employs variational wave functions that are a combination of permanents. These are bosonic counterpart of the fermionic Slater determinant…
Permanent variational wave functions for bosons
J. M. Zhang, H. F. Song, Y. Liu
We study the performance of permanent states (the bosonic counterpart of the Slater determinant state) as approximating functions for bosons, with the intention to develop variatio…
Witnessing a Poincaré recurrence with Mathematica
J. M. Zhang, Y. Liu
The often elusive Poincaré recurrence can be witnessed in a completely separable system. For such systems, the problem of recurrence reduces to the classic mathematical problem of…
Fermi's golden rule: its derivation and breakdown by an ideal model
J. M. Zhang, Y. Liu
Fermi's golden rule is of great importance in quantum dynamics. However, in many textbooks on quantum mechanics, its contents and limitations are obscured by the approximations and…
