چکیده:


Solid-state spin defects in 3D materials have shown remarkable capabilities in quantum sensing and information processing. While these materials are effective, the search for scalable alternatives is ongoing. Two-dimensional materials like hexagonal boron nitride (hBN) are emerging as promising candidates. The negatively charged boron vacancy (VB) in hBN exhibits exceptional room-temperature properties, positioning it as a compelling platform for scalable quantum technologies. This lecture explores recent advances in harnessing VB centers for quantum technologies, focusing on three interconnected pillars: spin control, strain-mediated coupling, and decoherence mitigation. First, we demonstrate efficient nuclear spin hyperpolarization using active spin driving and the Holstein-Primakoff transformation. This enables the initialization of large-scale quantum simulators from thermal spin baths. Second, we propose a strain-induced coupling scheme in hBN nanoribbons. This scheme demonstrates robust room-temperature entanglement and Dicke-Ising simulations. Finally, we investigate the decoherence dynamics of VB centers, focusing on the interplay between dipolar hyperfine interactions and spin-phonon coupling. Our findings provide a foundation for developing practical quantum devices that leverage the advantages of van der Waals materials.

In this talk, I will try to sketch the big picture of our universe's history (of course as far as we know till now). This leads us to the darkness, dark matter and dark energy, the standard model of cosmology. Then I will review very briefly the recent tensions and anomalies in this model. If we had time, I would like to end with my own question: Why is our universe so simple?

Abstract
Fractons, characterized by restricted mobility and governed by higher-moment conservation laws, represent a novel phase of matter with profound connections to tensor gauge theories and emergent gravity. I will systematically explore the duality between fractons and non-Lorentzian particles—specifically, Carroll and Galilean particles—within electromagnetic (EM) fields. By constructing canonical actions for fractons in rank-2 gauge fields, we derive their equations of motion and demonstrate that static fractons exhibit duality with the electric sector of Carroll particles, while mobile fracton dipoles correspond to both the electric and magnetic sectors of Galilean particles. Furthermore, by gauging the fracton algebra, we develop a geometric framework for fracton gravity, linking it to non-Lorentzian spacetime geometries. These results unify fracton dynamics with the non-relativistic and ultra-relativistic limits of physics, offering insights into emergent gravity and exotic condensed matter systems.

Abstract


I will argue that the usual effective field theory techniques break down in the rapdily expanding background of the early universe. The TCC ("Trans-Planckian Censorship Criterion") plays a key role in the argument. I will then discuss an attempt to obtain an emerging metric space-time and early universe cosmology starting from a quantum mechanical matrix model.
