Classical physics breaks down to the level of atoms and molecules. This was made
possible by the invention of a new apparatus that enabled the introduction of
measurements in microscopic area of physics. There were two revolutions in the way
we viewed the physical world in the twentieth century: relativity and quantum
mechanics. Quantum mechanics was born in 1924, through the work of Einstein,
Rutherford and Bohr, Schrödinger and Heisenberg, Born, Dirac, and many others. The
principles of quantum mechanics that were discovered then are the same as we know
Colours! The most beautiful of buds – an apple bud in my garden changes colour
from red to rosy after a few days. Why? It then explodes into a beautiful pale rosy
ﬂower. After a few months what was once a ﬂower looks completely different: it
has become a big, round and red apple. Look at the apple skin. It is pale green,
but moving along its surface the colour changes quite abruptly to an extraordinary
vibrant red. The apple looks quite different when lit by full sunlight, or when placed
in the shade....
The development of quantum mechanics has taken physics in a vastly new direction from that of classical physics from the very start. In fact, there continue at present to be many developments in the subject of a very fundamental nature, such as implications for the foundations of physics, physics of entanglement, geometric phases, gravity and cosmology and elementary particles as well. It is hoped the papers in this volume will provide a much needed resource for researchers with regard to current topics of research in this growing area....

Quantum-squeezing effects of strained multilayer graphene NEMS
Yang Xu1*, Sheping Yan1, Zhonghe Jin1* and Yuelin Wang2
Abstract Quantum squeezing can improve the ultimate measurement precision by squeezing one desired fluctuation of the two physical quantities in Heisenberg relation. We propose a scheme to obtain squeezed states through graphene nanoelectromechanical system (NEMS) taking advantage of their thin thickness in principle.
