Universal power-law decay of the impulse energy in granular protectors.
TLDR
A universal power-law behavior is found in time for the leakage of the impulse energy confined inside various granular containers.
Nondestructive identification of impurities in granular medium
We found differing characteristics in the backscattered signal depending on the presence of light and heavy impurities in a granular chain. The difference is due to soliton confinement in the region
Local and nonlocal entanglement for quasiparticle pairs induced by Andreev reflection
We investigate local and nonlocal entanglement of particle pairs induced by direct and crossed Andreev reflections at the interfaces between a superconductor and two normal conductors. It is shown
Current rectification by spontaneous symmetry breaking in coupled nanomechanical shuttles.
TLDR
It is shown that left-right-symmetric double shuttles may generate direct net current due to bistable motions caused by parametric instability, and the symmetry-broken direct current appears near omega.
Giant persistent currents in the open Aharonov-Bohm rings
We investigate persistent currents in the Aharonov-Bohm rings coupled to external leads. For a contacted double-ring structure, it is found that the flux-independent perfect transmission occurs at
POWER LAWS IN NONLINEAR GRANULAR CHAIN UNDER GRAVITY
The signal generated by a weak impulse propagates in an oscillatory way and dispersively in a gravitationally compacted granular chain. For the power-law type contact force, we show analytically that
Heisenberg picture approach to the invariants and the exact quantum motions for coupled parametric oscillators
For N-coupled generalized time-dependent oscillators, primary invariants and a generalized invariant are found in terms of classical solutions. Exact quantum motions satisfying the Heisenberg
