Bongjae Kim - Competing magnetisms and onset of the static magnetic order in Sr2RuO4
This talk was part of the Workshop on "Spin-Orbit Entangled Quantum Magnetism" held at the ESI September 23 -- 27, 2024.
Sr2RuO4 has long been a system of interest due to its unconventional superconducting properties. While paramagnetic metal in its normal state, the system harbors interesting landscape of competing magnetic instabilities that are intricately linked to its superconducting pairing symmetries. In this talk, I will discuss the various magnetic features we have investigated in the Sr2RuO4 and then discuss the various magnetic features we have investigated in Sr2RuO4, highlighting their intimate connection to experimental findings. Specifically, we attempt to explain the onset of a static magnetic order beyond a critical strain by combining the first-principles density functional theory and Moriya’s self-consistent renormalization theory.

    Excellent presentation. An error that needs revision is the fundamental aspect of life, time 2'35", defiance of the 2nd Law. No machine can maintain homeostasis, it needs an external source of energy greater that homeostasis it produces. Thus, the AC may cool your room, but the total heat, considering the outside, is greater with the AC on. The order that a molecule imparts on the environment, through life, considering all the heat exchanges, violates the 2nd Law, and nothing in this universe is supposed to violate the 2nd Law. Hence, we need to re-think our laws of physics. I think Schrödinger told the whole story.

    @1:20 you are therefore stating "an agent's personal beliefs" could "derive from pure quantum states". This is one dopey mix-up of concepts. Pure quantum states relate to a theory of physics. Sure, "people" came up with QM and this theory informs our beliefs, but the physical reality we perceive is not the source of our beliefs. Our beliefs are a category of mental qualia, and physics has absolutely no clue where those qualia come from. They are not brain states. They are something else, and it is not physics. So they cannot derive from quantum mechanics (which is physics). Unless you are prepared to do violence to the definition of the word "physics", but then you are causing a mess of mixing of domains of scientific modelling, which is unhealthy in my view (especially for clean physics pedagogy --- and I am by no means an establishment guy, I do however value good pedagogy in learning, even if the student has to find it for themselves).
