Quantum Physics from Beginner to Expert (Quantum mechanics)
This course is for everyone: beginner to expert!
We will cover the whole band width of quantum mechanics starting from the initial experimental observations and ending up with relativistic quantum theory.
Quantum mechanics is arguably among the most fascinating fields of science.
It has made numerous appearances in modern pop-culture and is present in our everyday lives. Still, it is also very challenging to get a grasp at this topic – even understanding the most fundamental concepts can be very difficult without instructions.
However, I think that this most fascinating field of science is often taught either too vague or with a too strong focus on the mathematics. Instead of watching random Youtube videos or going through hundred of hours of university courses, I think that Udemy courses are a nice platform for purposeful learning. You are kindly invited to join this carefully prepared course that will teach you the 101 of quantum physics.
Why me?
My name is Börge and I am a postdoc working as a scientist in quantum theory. Due to my expertise in the field, I know which topics are most important and which parts can be cut short (especially the very dry parts). I have not forgotten the time when I learned about quantum physics and still remember the problems that I and other students had. I have refined my advisor skills as a tutor of Bachelor, Master and PhD students in theoretical physics.
This course is for you if you …
-
… have ever wondered what is the big deal with quantum physics
-
… want to know why we need quantum physics
-
… want to learn the methods how to actually calculate quantum problems like the tunnel effect
-
… want to walk comfortably in the quantum world without being totally overwhelmed by its difficult language
-
… have interest in popular physics phenomena like quantum computing or superconductivity and want to understand their core ideas and relations to quantum mechanics
-
… are about to attend a university course
-
… if you have already attend a university course and want to learn what comes next
or
-
… if you simply want to have a carefully condensed refresher before your exams 🙂
Welcome
Why do we need quantum physics?
The Schrödinger equation
Solving stationary examples
Optional: Programming Session
More theoretical background
Typo: In the "definition" of the delta distribution, the limit of a should go to zero and not infinity.
Comment:
~1:47 I forgot the tilde (~) on top of psi(p,t) in the second equation
Second quantization: The harmonic oscillator
Correction: 05:44
In the third line, the term on the right should be 1/2*a^+ (like in the line before) and not 1/2*a.
Correction:
~11:05: The last term should be 1/sqrt(1-x^2) instead of 1/(1-x^2)
Real-world example: The hydrogen atom
Corrections:
~2:00: Third equation: epsilon/r^2 should actually be epsilon/r.
~7:38: k^2 d/d rho should actually be the second derivative k^2 d^2/d rho^2
Relativistic quantum theory & Electron spin
Correction:
~1:40 I missed the square on the E (energy) in the second equation: E^2/c^2-p^2 = m^2c^2
Correction:
~1:14 I missed the square on the E (energy) in the second equation: E^2/c^2-p^2 = m^2c^2
