Normie Jean B. Sajor Quantum mechanics is one of the most functional theories in the world of physics. It describes the workings of particles, atoms, and molecules with extraordinary accuracy and also explains the action of lasers and transistors. Yet, the debate about the relation of quantum mechanics to the familiar physical world continues. For […]

### Simultaneous Diagonalization of Hermitian Matrices

Friday, May 8th, 2009by MARYJANE D. MADULARA In an earlier post about the properties of Hermitian operators, it was noted that quantum operators of physical significance are Hermitian by type. Here we discuss more fully about Hermitian matrices. A n x n matrix is Hermitian if it is equal to its corresponding adjoint matrix. Now, for each Hermitian […]

### Properties of Quantum Oscillators 1

Friday, April 3rd, 2009by SIMON JUDE BURGOS In this post we investigate the properties of a quantum oscillator by using an algebraic tool in quantum mechanics called ‘ladder operators’. Using the ladder operator it becomes easy to find the following properties for a quantum oscillator in a given energy level: the average position and momentum and the square […]

### For a Deeper Understanding and Appreciation of our Physical World

Friday, November 28th, 2008In June 2008, for the first time in the southern Philippines the biggest group of more than a dozen and a half graduate students studying quantum mechanics was ever assembled. Never mind that the Philippines was discovered by Magellan in the year 1521. Anyway, quantum mechanics was only formulated in 1926; relatively quite recent. Quantum […]
