Properties of fermionic systems with the Path-integral ground state method
Sebastian Ujevick, V. Zampronio, B. R. de Abreu +1
We investigate strongly correlated many-body systems composed of bosons and fermions with a fully quantum treatment using the path-integral ground state method, PIGS. To account fo…
Using Nanoresonators with Robust Chaos as HRNGs
Lucas R. Rodrigues, W. G. Dantas, Sebastian Ujevic +1
In this paper, we investigate theoretically the potential of a nanoelectromechanical suspended beam resonator excited by two-external frequencies as a hardware random number genera…
Kinetic energies of liquid and solid phases of He
E. J. Rugeles, Sebastian Ujevic, S. A. Vitiello
Kinetic energies of a system of He are investigated at zero temperature. The multi-weight extension to the diffusion Monte Carlo method is used to implement the Feynman-Hellman…
Cyclotron enhancement of tunneling
M. V. Medvedeva, I. A. Larkin, S. Ujevic +2
A state of an electron in a quantum wire or a thin film becomes metastable, when a static electric field is applied perpendicular to the wire direction or the film surface. The sta…
Analysis of the contributions of three-body potentials in the equation of state of 4He
Sebastian Ujevic, S. A. Vitiello
The effect of three-body interatomic contributions in the equation of state of 4He are investigated. A recent two-body potential together with the Cohen and Murrell (Chem. Phys. Le…
