Abstract: We present a model of quantum cosmology based on anti-de Sitter/conformal field theory (AdS/CFT) holography. The spacetimes in our construction are time-symmetric, big-bang/big-crunch cosmologies with a negative cosmological constant $\Lambda$. In the simplest version of our model the cosmology lives inside a spatially finite bubble within an otherwise empty AdS spacetime. By studying the thermodynamic and geometric properties of this spacetime, we provide evidence that the ``bubble of cosmology'' spacetime has a well-defined dual CFT description.

Abstract: Crystalline graphene multilayers present a rich playground to explore correlated electronic phenomena in a tunable and ultra-clean setting. For instance, Bernal bilayer graphene and rhombohedral trilayer graphene host multiple symmetry-broken metallic phases at low temperature, as well as unconventional superconductors with different pairing symmetries.

"Exotic weak decays offer a unique way to probe physics beyond the Standard Model in a low-energy regime using the atomic nucleus as a window to complement the high-energy searches done at particle accelerator facilities. However, in order to extract the relevant physics parameters from experimental observations, inputs from nuclear theory are required.

[abstract] Quasiprobability representations serve as a bridge between classical and quantum descriptions of physical systems. In these representations, nonnegativity allows for a probabilistic interpretation, aligning the description with classical physics.

Abstract:
Rhombohedral(R)-stacked TMD means the neighbouring layers are oriented in the same direction, which can be obtained through either chemical synthesis or artificial stack with a small twist. The investigation into how the stacking order determines the properties of TMD homobilayers is crucial for understanding the exotic physics observed in two-dimensional semiconductors.

Abstract: By quenching the interaction strength, we induce and study a topological dynamical phase transition between superconducting phases of a planar fermionic model. Using the Lindblad Master Equation approach to account for the interactions of Bogoliubov quasiparticles among themselves and with the fluctuations of the superconducting order parameter, we derive the corresponding relaxation dynamics of the order parameter. To fully characterize the phase transition, we also compute the fidelity and the spin-Hall conductance of the system.

| Event Location: HENN 202 | Speaker: Heather Gray (UC Berkeley)
Abstract:
The search for the Higgs boson was central to the conception and design of the LHC detectors. However, measurements of the Higgs coupling to the second and third-generation quarks were regarded as extremely challenging and, in some cases, impossible. Scientific ingenuity and original thought have allowed ATLAS and CMS to probe the coupling of the Higgs boson to quarks. I will discuss techniques (including machine learning) used to achieve this and provide a brief perspective on future directions.

Abstract: In the first part of my talk, I will discuss a Holstein-like model with two electrons nonlinearly coupled to quantum phonons. Using an efficient method based on full quantum approach [1-4] we simulate the dynamical response of a system subject to a short spatially uniform optical pulse that couples to dipole-active vibrational modes. Nonlinear electron-phonon coupling can either soften or strengthen the phonon frequency in the presence of electron density [5].

Abstract:
I will discuss the need to extend the Standard Model of particle physics in order to describe the dark matter, a mysterious substance whose existence can be inferred from cosmological measurements, but whose fundamental nature remains unknown. I’ll discuss how a broad strategy of searching for dark matter using techniques from particle physics and astronomy maximize our chances of successfully discovering its identity, and what this could mean for future research in particle physics.

Abstract: In my presentation, I will give an overview of three primary areas that have been my focal research interests at NOMATEN CoE: i) crystal and amorphous plasticity, ii) transport properties of high-entropy alloys (HEAs), and iii) micro-structural informatics. In i), my research has employed statistical physics to unravel the microscopic basis of plasticity based on the collective dynamics of shear transformation zones in amorphous solids as well as dislocations mechanics in crystalline metals.

Abstract:
Rubin Observatory is on track to start operations of the Legacy Survey of Space and Time (LSST) in fall 2025, setting off a rush of data that will be massive (20TB per night) and nonstop for ten years. The LSST will survey approximately 20,000 square degrees of sky in ugrizy bandpasses, with highly accurate astrometry and photometry, with individual images reaching depths of about 24.5 in r band.

Abstract:
The Standard Model of particle physics cannot be the final word on how to understand fundamental particles theoretically. The missing pieces, intriguing patterns and extreme hierarchies of the Standard Model demand explanations, but any new theory must tread a tightrope of increasingly precise measurements.

Abstract: Sensors that leverage quantum phenomena to measure physical quantities harbor many attractive features beyond classical sensors. Solid-state quantum sensors, with the nitrogen-vacancy (NV) center in diamond a forefront technology, are particularly attractive for their compatibility with biological and condensed matter systems, offering ultra-high spatial resolution and sensitivity over a wide temperature range, while being quantitative and non-invasive.

Abstract: When two atomically-thin layers of a material are stacked one atop each other, with a relative twist angle between them, properties can emerge that bear little resemblance to the behavior of the individual layers. Though much can be predicted and designed about such structures, I will share two vignettes about how my students aimed for a particular behavior but found something quite different.
