A theoretical model based on the single electron tunneling phenomenon is employed to calculate the time-dependent electrical resistance of an Ag–Ag 2 S–Pt atomic switch at different applied voltages. While a negative voltage is applied to Pt elec

Through MD simulation of the transient heat pulse propagation in asymmetric Y junction, we report a novel type of controllable heat conduction in graphene nanostructure. The Y junction consists of a steam breaking into a wide branch and a narrow bran

In this work, the expansion dynamics of a helium plasma jet in ambient air is examined. By using a fast imaging technique, the expansion of plasma jet from glass nozzle to air is captured which is in the form of plasma bullet propagating into the air

The entanglement swapping protocol is analyzed in a relativistic setting, where shortly after the entanglement swapping is performed, a Bell test is performed. For an observer in the laboratory frame, a Bell violation is observed between the qubits w

Recent work has proposed that the interaction between ordinary matter and a stochastic gravitational background can lead to the decoherence of large aggregates of ordinary matter. In this work we point out that these arguments can be carried over to

Signal velocity is calculated in a medium with negative group delay (NGD). By accounting for the medium and the detector noise sources, the time varying probability of error at the detector [ Pe ( t ) ] is evaluated in the NGD channel and a normal di

We analyze residual spectra of 3 K blackbody radiation (CMB) using non-extensive thermostatistics with a parameter q - 1. The limits of vertical bar q - 1 vertical bar < 1.2 x 10(-5) and the temperature fluctuation vertical bar delta T vertical bar <

Taking the intrinsic decoherence effect into account, the tripartite nonlocality is measured by the extent of violation of multipartite Bell inequality in a three-qubit Heisenberg XY chain in the presence of an external magnetic field. It is shown th

We study the time-evolution of entanglement and Bell-inequality violation of a two-qubit system in the presence of classical Ornstein–Uhlenbeck noise. It is shown that both disentanglement and Bell nonlocality depend strongly on the initial paramet

The boson-detector model is generalized to investigate the decay of two-particle coherence. It is found from the visibility of the two-particle interferometer that the detector system not only destructs the coherence but also creates the correlation
