Are we living in a simulation?
This multi-part series by Klee Irwin, founder of Quantum Gravity Research, is about the nature of reality. One philosophy to consider is materialism, which is the guess that reality is not made of information at its core but is made of material or matter. The digital physics revolution is the increasingly popular belief among physicists that materialism is a false philosophy and that reality is literally made of information vs being conveniently described by it.
If reality is made of information, two candidates for what its substrate would be include: (1) An emergent universal computer. Or (2) an emergent universal mind. Either one could serve as the substrate to hold and process information.
The series starts with an emphasis on the instability of human civilization in the 21st century and how quickly old scientific and cultural belief systems are changing. It ends with the provocative suggestion that a clearer scientific picture of what reality is could shift humanity off course from its current high potential for apocalypse. Specifically, if the truer picture turns out to be a status quo rejection of the ancient philosophy of materialism, the implication is that it would change how humanity evolves and interacts on this planet going forward.

![Caroline S. Gorham - What Hopf Fibrations can tell us about crystallization and glass formation

QGR visitor and friend Caroline Gorham delivered a guest lecture to the QGR team on what Hopf Fibrations can tell us about crystallization and glass formation.
This research elucidates the topological origins of the formation of crystalline and non-crystalline solid states, by adopting a quaternion orientational order parameter. Crystalline solids are considered to form in “restricted dimensions’’ 4D/(3D+1t), by a defect-binding topological transition of third homotopy group defects and disclinations, as a higher-dimensional analogue to the formation of topologically-ordered superfluid states in “restricted dimensions’’ 2D/(1D+1t) (e.g., Josephson junction arrays). Ultimately, it is suggested that, the notion of restricted dimensions may be interpreted by considering the dimensionality of the topological defects associated with the complex or quaternion order parameter (fiber space of the 1st and 2nd Hopf fibrations). This work thereby generalizes the fundamental concepts of: Bose-Einstein condensation, the Hohenberg-Mermin-Wagner theorem and Berezinskii-Kosterlitz-Thouless (BKT) topological ordering transitions from complex to quaternion Lie algebra domains. O(n) quantum rotor models mathematically model rotating Bose-Einstein condensates that exist in “restricted dimensions.” These models allow for the existence of frustrated ground states and, ultimately, a quantum phase transition between orientationally-ordered and orientationally-disordered ground states. These spectrum of ground states are ultimately realized in the laboratory, e.g., a superfluid-to-Mott insulator transition (complex) and a crystalline-to-glass transition (quaternion). The Kauzmann point (``ideal glass transition’’) is identified as a self-dual critical point between crystalline and non-crystalline solid states, achieved at a critical value of geometrical frustration (e.g., in topologically close-packed crystals) or for an infinitely slow cooling rate in glass-forming liquids. The transport properties of the ground states depend intimately on the ratio of potential and kinetic energies in the relevant O(n) quantum rotor model. Using this topological viewpoint, the inverse thermal transport properties of crystalline and non-crystalline solid states (above approximately 50 K) are considered alongside the electrical transport properties of JJAs across the singularity at the superconductor-to-superinsulator transition.
Caroline Gorham received her Ph.D. in Materials Science and Engineering at Carnegie Mellon University in August 2018. Her primary research interests have focused on the applications of topology to understand structure and thermal transport properties in crystalline and non-crystalline solid state forms of condensed matter.
