Many-body wavefunctions for normal liquid $^3$He

, 2006
We present new trial wave-functions which include 3-body correlations into the backflow coordinates and a 4-body symmetric potential. We show that our wavefunctions lower the energy enough to stabilize the ground state energies of normal liquid $^3$He in

Non-Markovian dynamics for an open two-level system without rotating wave approximation: Indivisibility versus backflow of information

, 2012
By use of the two measures presented recently, the indivisibility and the backflow of information, we study the non-Markovianity of the dynamics for a two-level system interacting with a zero-temperature structured environment without using rotating wave

Spin-liquid and magnetic phases in the anisotropic triangular lattice: the case of $\kappa$-(ET)$_2$X

, 2009
The two-dimensional Hubbard model on the anisotropic triangular lattice, with two different hopping amplitudes $t$ and $t^\prime$, is relevant to describe the low-energy physics of $\kappa$-(ET)$_2$X, a family of organic salts.

Development of an Air Duct Damper to Prevent Backflow Odor from the Ventilation Shaft in Buildings

Journal of Asian Architecture and Building Engineering, 2017
Nowadays, backflow odor, along with floor noise, has been recognized as an environmental right dispute element between the units within a multi-unit dwelling in Korea because it causes not only foul odors flowing back into the unit vent pipe to flow ...

Trial wave functions for High-Pressure Metallic Hydrogen

, 2007
Many body trial wave functions are the key ingredient for accurate Quantum Monte Carlo estimates of total electronic energies in many electron systems. In the Coupled Electron-Ion Monte Carlo method, the accuracy of the trial function must be conjugated ...
