The fractional quantum Hall effect in wide quantum wells
... spatial separation of the wavefunctions is much larger in the wider quantum well. This has important implications. Our observation of a 5/2 state in the 1SB at a non integer filling of the 2SB implies that the topmost occupied LLs of both SBs are partially filled. They must be pinned at the same ene ...

... Atomic Orbitals and Quantum Numbers • Quantum numbers specify the properties of atomic orbitals and the properties of electrons in orbitals. • The principal quantum number, symbolized by n, indicates the main energy level occupied by the electron. 1, 2, 3, etc. as n increases the electron’s energy l ...

Temperature Dependence of the Energy Gap of InP Quantum Dots
... This paper presents a sophomore-level experiment that allows students to see the “particle-in-abox” behavior of a real system (quantum dots of different sizes) and explores the temperature dependence of the quantum dots’ energy gap. Quantum dots are nanometer-sized clusters of atoms that contain any ...

A Brief Review on Quantum Bit Commitment

This impossibility comes from the fact that a cheating strategy using EPR pairs can always be implemented. Thus, different approaches have been presented in order to avoid the no-go theorem [1 ...

An Accidental Relationship Between a Relative Quantum
... Concurrence and other measures of entanglement, being nonlinear functions of the density operator, can not be directly measured. Therefore, the search of observables related to entanglement, including entanglement witnesses, is an important goal. In this paper we show a result in that direction. For ...
