Stochastic resonance in bistable systems: The effect of simultaneous additive and multiplicative correlated noises

open access: yes, 1999
We analyze the effect of the simultaneous presence of correlated additive and multiplicative noises on the stochastic resonance response of a modulated bistable system. We find that when the correlation parameter is also modulated, the system's response,

Fermi Arcs Dominating the Electronic Surface Properties of Trigonal PtBi2

open access: yesAdvanced Physics Research, Volume 4, Issue 5, May 2025.
Trigonal PtBi2 is a Weyl semimetal with recently demonstrated surface superconductivity. Scanning tunneling spectroscopy of the quasiparticle interference in the normal state of this material, combined with density functional theory calculations, reveals that the scattering between Fermi arcs dominates the interference spectra, providing conclusive ...

Structure and magnetism of orthorhombic epitaxial FeMnAs [PDF]

open access: yes, 2013
The molecular beam epitaxy growth of Fe on MnAs/GaAs(001) leads to the formation of an epitaxial FeMnAs phase at the Fe/MnAs interface. The investigation of the structure by high angle annular dark field imaging in a scanning transmission electron ...

Unifying approach for fluctuation theorems from joint probability distributions

open access: yes, 2010
Any decomposition of the total trajectory entropy production for Markovian systems has a joint probability distribution satisfying a generalized detailed fluctuation theorem, when all the contributing terms are odd with respect to time reversal.
