We discuss a simple model for creation of entanglement in a system composed of two two-level atoms interacting with a common environment. The role of the environment in entangling and disentangling of the atoms is explored. We demonstrate how the spontaneous decay of an initial excitation of the system can create a transient entanglement between the atoms. The opposite situation is also discuss...

T his is the fourth paper in our series, identifying unusual phenomena and providing recommendations for the thermo-mechanical characterization of shape memory alloy (SMA) wire. Part 11 provided basic background of the martensitic transformations between austenite (A) and martensite (M) which are responsible for the shape memory (SM) effect and superelasticity (SE). Two typical NiTi SMA alloys ...

Finding the exotic phenomena in strongly correlated electron systems (SCESs) and understanding the corresponding microphysics have long been the research frontiers of condensed matter physics. The remarkable examples for the intriguing phenomena discovered in past years include unconventional superconductivity, heavy Fermion behaviors, giant magneto-resistance and so on. A fascinating type of r...

Leptospirosis, a disease of great significance in tropical countries, presents commonly as a biphasic illness with acute febrile episode in the first phase followed by a brief afebrile period and then by the second phase of fever with or without jaundice and renal failure. However, it has varied manifestations and unusual clinical features ascribed to immunological phenomena can occur due to th...

This paper studies a system of coupled discrete fractional-order logistic maps, modeled by Caputo’s delta fractional difference, regarding its numerical integration and chaotic dynamics. Some interesting new dynamical properties unusual phenomena from this chaotic-map are revealed. Moreover, the coexistence attractors, necessary ingredient existence hidden is proved analyzed.

Ultrafast laser pulses can be used to drive materials into nonequilibrium states that have unusual properties and are promising for technological applications. Different classes of phenomena observed during after the optical illumination. This Colloquium discusses recent developments in this field, prospects using these techniques create with novel functionalities a controlled way.
