Dirac Landau Levels Using Cylindrical Coordinates | Relativistic Quantum Mechanics Dietterich Labs 2023-01-08 | In this video, I show you one last technique for solving the Dirac equation for relativistic Landau Levels, and that is the use of the power series method in cylindrical coordinates.Clarification: By uncoupled, I don't just mean that there is no term in which k_z and m multiply each other. I am also referring to the fact that they multiply different alpha matrices. The relations satisfied by the alpha matrices ensure that cross terms don't show up. In this video, I only remembered to mention this at the very end.That Cartesian video:youtu.be/M9w2Plj7brwThe ladder operator video:youtu.be/aDAw3glRHDwMy Quantum Mechanics Lecture Series:youtube.com/playlist?list=PLSpklniGdSfSsAFCzO-YWGlJ4TNv8sMdy

Annoying Ass Spinor Spherical Harmonics Identity | Quantum Mechanics Dietterich Labs 2022-12-27 | In this video, I show how to do a tricky homework problem that I had a while ago.My Quantum Mechanics Lecture Series:youtube.com/playlist?list=PLSpklniGdSfSsAFCzO-YWGlJ4TNv8sMdyTypo: At 5:43, it should be Y(l , m+½) = (Sqrt { [ ( 2l + 1 ) ÷ 4π ] ⋅ ( l − m − ½ )! ÷ ( l + m + ½ )! } )⋅[exp i(m+½)φ]⋅P(l , m+½)
Bhabha Scattering With The Spinor Helicity Formalism | Quantum Field Theory Dietterich Labs 2022-12-09 | In this video, I use the spinor helicity formalism to perform a calculation that I have already done in another video (the calculation of the ultra-relativistic Bhabha differential scattering cross section), for practice and comparison.Here is my previous video on Bhabha scattering:youtu.be/iXgpsPYZ7hgNote: the bosonic normalization I chose to use in the general differential scattering cross section is not arbitrary, apart from not including mass factors. It is the one consistent with the usual spinor-helicity formalism.

The Variational Method (QM approximation) | Quantum Mechanics Dietterich Labs 2022-09-11 | In this video, I introduce, prove, and demonstrate the variational method from quantum mechanics. A technique used to compute an upper bound on the energy of the ground state of a quantum system.My Quantum Mechanics Lecture Series:youtube.com/playlist?list=PLSpklniGdSfSsAFCzO-YWGlJ4TNv8sMdyClarification: I ignored the negative root because it would not lead to a smooth trial function, and would therefore be much worse than the simple square guess that we were trying to improve on. Also, one in general has to check that the root one does select actually is a minimum, a step that I skipped here.

I then show some of the germinated rosewood seeds.To be clear: when I say "less reputable suppliers", I mean from a seed viability perspective, not from a plant poaching perspective. I do not support plant poaching, and do not buy poached plants.

When Will The Ball Fall? | Classical Mechanics Dietterich Labs 2022-08-03 | In this video, I demonstrate a way of using Lagrange multipliers to solve for when a ball looses contact with a circle that it's rolling off of. This technique could be applied to other cases where a constraint applies for only some of the time evolution of a system, and it is necessary to calculate the point where it stops applying.Typo at 2:25: On the RHS of the first equation of motion, there should be a square on the theta-dot.

The Double Pendulum | Classical Mechanics Dietterich Labs 2022-06-19 | In this video, I show you how to handle the double pendulum problem mathematically. We derive the lagrangian, and the equations of motion. We then make the small angle approximation, and calculate the normal frequencies and normal modes.Typo: In my initial expression for y_1, the angle should be theta_1.Note: A good point was made in the comments section of this video. What I called an eigenvalue problem isn't exactly that, because neither V-tilde of T-tilde are the identity. One could take the base matrix equation, and multiply it by T-tilde-inverse to convert it into one, but that doesn't change how the system is actually solved. I therefore kept calling it an eigenvalue problem without fully converting it into one.

Quantum ElectroWeak Theory & Spontaneous Symmetry Breaking | Quantum Field Theory Dietterich Labs 2021-01-24 | In this video, I explain how spontaneous symmetry breaking works in the quantum electroweak theory.Quantum Field Theory Lecture Series: youtube.com/playlist?list=PLSpklniGdSfSsk7BSZjONcfhRGKNa2uouThere are a few places in this video where I wrote out the finished charged current lagrangian without using the psi notation that I broadly adopted for Dirac fermion fields. The way I accidentally wrote it is a common alternative notation, and the context still makes everything clear, so it shouldn't be a big problem, but I still wanted to clarify.Also, the subscript "SM" on the last two Lagrangians is supposed to be "WSM" standing for Weinberg-Salam Model.When I state the gauge transformation laws, "R" refers to the right handed sector, which consists only of e_R. I meant to just write e_R, but I accidentally mixed in an alternative notation again.
SU(3) Higgs Mechanism Example | Quantum Field Theory Dietterich Labs 2020-12-28 | In this video, I work through the problem of spontaneous symmetry breaking in SU(3) Yang-Mills theory, induced by a Higgs field transforming in the fundamental representation.Quantum Field Theory Lecture Series: youtube.com/playlist?list=PLSpklniGdSfSsk7BSZjONcfhRGKNa2uouIt's worth pointing out that I chose to leave the vector boson interactions inside the field strength tensor terms, to keep the result compact. This does mean that the Proca Lagrangian density doesn't appear explicitly in the final answer, although it is clearly present. It also means that the massless and massive vector boson Lagrangians do contain fields of the other type via the still-implicit vector boson interaction terms. Because it is clear where all the important parts are, I decided that this would be a good compromise between clarity and compactness.
Fermion Masses From Spontaneous Symmetry Breaking | The Yukawa Interaction | Quantum Field Theory Dietterich Labs 2020-12-03 | In this video, I explain how spontaneous symmetry breaking can be used to produce masses for more than just vector bosons via the Higgs mechanism.

Spontaneous Symmetry Breaking And The Higgs Mechanism | Quantum Field Theory Dietterich Labs 2020-09-29 | In this video, I use a set of example theories to explain and demonstrate spontaneous symmetry breaking and the Higgs mechanism. Quantum Field Theory Lecture Series: youtube.com/playlist?list=PLSpklniGdSfSsk7BSZjONcfhRGKNa2uou Superfluid Helium Resonance Experiment video: youtu.be/unUNQNmuvUQA clarification on tachyon condensation:Tachyon condensation handles the tachyon problem at high energy in theories that are used for phenomenology. The first two theories discussed in this video only contain the scalar field used for breaking symmetry. There is therefore nothing for the tachyons present at high energy to decay into. Tachyon condensation therefore doesn’t take care of the problem for these theories. This is ok, however, because they aren’t used for phenomenology. In theories like the third example and ones like the standard model, which are used for phenomenology, tachyon condensation is free to take place on account of there being many particles that the tachyons can decay into. So when I say that tachyons don’t imply unphysicality at high energy, I mean that they don’t guarantee it. It ultimately depends on the theory.Generalizing Gladstones Theorem To Complex Fields:The way that I stated the Goldstone theorem in this video was that the number of broken generators (and Nambu-Goldstone bosons) is equal to the number of unbroken directions in isospin space, resulting from the zero isospin components in the new vacuum about which we were expanding the theory. This makes perfect sense when the scalar field is real, and there is therefore one field per component. How this could be correct for a complex scalar field, where there are two fields per component is a little less obvious. It turns out that the immediate generalization is to say that there are as many broken generators (and Nambu-Goldstone bosons) as there are fields set equal to zero in the vacuum about which we are expanding. However, we can always recast an N component complex scalar field as a 2N component real scalar field, in which case the original statement would apply again. So in a round about way, that statement of the Goldstone theorem is generally valid, even for a complex scalar field.Take the U(1) example in this video. It includes a one component complex scalar field. The new vacuum about which we are expanding the theory is real. One field has therefore been set equal to zero in that vacuum, namely the imaginary component. From this and the Goldstone theorem, we would expect one broken generator, one Nambu-Goldstone boson, and one massive gauge field. This is exactly what we see.We could always recast the U(1) theory as an SO(2) theory with a two component real scalar field, instead of a one component complex scalar field. The new vacuum would then have one zero component, and one real constant component, and the earlier statement of the Goldstone theorem would apply and produce the same answer.One final note on the U(1)/SO(2) problem. One is used to seeing residual symmetry associated with zero isospin components in the scalar field, but in U(1)/SO(2) theory, there is only one generator to be broken, so there is no residual symmetry.
