Tackling the Fermionic Sign Problem in the Auxiliary-Field Monte Carlo Method
G. Stoitcheva, W. E. Ormand, D. Neuhauser +1
We explore a novel and straightforward solution to the sign problem that has plagued the Auxiliary-field Monte Carlo (AFMC) method applied to many-body systems for more than a deca…

Hydrodynamic Tensor-DFT with correct susceptibility
Igor V. Ovchinnikov, Lizette A. Bartell, Daniel Neuhauser
In a previous work we developed a family of orbital-free tensor equations for DFT [J. Chem. Phys. 124, 024105 (2006)]. The theory is a combination of the coupled hydrodynamic momen…

Bogoliubov-like mode in the Tonks-Girardeau Gas
Igor V. Ovchinnikov, Daniel Neuhauser
We reformulate 1D boson-fermion duality in path-integral terms. The result is a 1D counterpart of the boson-fermion duality in the 2D Chern-Simons gauge theory. The theory is consi…
