| Event Location: BRIM 311 | Speaker: Domenico Giuliano – Department of Physics, Università della Calabria, Italy
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.

| Event Location: BRIM 311 | Speaker: Janez Bonca – University of Ljubljana
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].

| Event Location: HENN 202 | Speaker: Tim Tait, University of California, Irvine
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:
Gravitational wave astronomy is entering a golden era of discovery, and many key science goals of this new frontier rely on 'multi-messenger’ observations that leverage the combination of both 'cosmic messengers' of gravitational waves and light.

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.

Abstract: Ultrafast optoelectronic circuits offer new opportunities for investigating and controlling the electrical responses of microstructured quantum materials and heterostructures at femtosecond timescales and THz frequencies. Based on metal waveguides and laser-triggered photoconductive switches, these chip-scale circuits can be interfaced to quantum materials to directly probe the ultrafast flow of electrical currents or perform near-field THz spectroscopy on length scales orders of magnitude smaller than the diffraction limit.

Abstract: DNA, RNA and proteins, which drive life, have complicated, constantly changing structures. For example, DNA inside cells is supercoiled, and the amount of supercoiling is constantly under flux.
This supercoiling can drive structural transitions, such as AT-rich regions in under-twisted DNA denaturing under physiological conditions.

Abstract:
The Callan Rubakov Effect describes the interaction between (massless) fermions and a smooth monopole in 4d gauge theory. In this scenario, the fermions can probe the UV physics inside the monopole core which leads to interesting effects such as proton decay in GUT models. However, the monopole-fermion scattering appears to lead to out-states that are not in the perturbative Hilbert space. In this talk, we will review this issue and propose a new physical mechanism that resolves this long-standing confusion.
