Kavli Affiliate: Lars Bildsten | First 5 Authors: William C. Schultz, Benny T. H. Tsang, Lars Bildsten, Yan-Fei Jiang, | Summary: Observations indicate that turbulent motions are present on most massive star surfaces. Starting from the observed phenomena of spectral lines with widths much larger than thermal broadening (e.g. micro- and macroturbulence) to the detection […]

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Yijian Zou, Paolo Glorioso, Ehud Altman, Matthew P. A. Fisher | Summary: We investigate the prospects of employing the linear cross-entropy to experimentally access measurement-induced phase transitions (MIPT) without requiring any postselection of quantum trajectories. For two random circuits that are identical in […]

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Jong Yeon Lee, Wenjie Ji, Zhen Bi, Matthew P. A. Fisher, | Summary: Measurements allow efficient preparation of interesting quantum many-body states exhibiting long-range, topological, or fractonic orders. Here, we prove that the so-called conformal quantum critical points (CQCP) can be obtained by performing general […]

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Jong Yeon Lee, Wenjie Ji, Zhen Bi, Matthew P. A. Fisher, | Summary: Measurements allow efficient preparation of interesting quantum many-body states with long-range entanglement, conditioned on additional transformations based on measurement outcomes. Here, we demonstrate that the so-called conformal quantum critical points (CQCP) can […]

Kavli Affiliate: Lars Bildsten | First 5 Authors: Adam S. Jermyn, Evan B. Bauer, Josiah Schwab, R. Farmer, Warrick H. Ball | Summary: We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). The new auto_diff module implements automatic differentiation in MESA, an enabling capability that alleviates the need […]

Kavli Affiliate: David Gross | First 5 Authors: Felipe Montealegre-Mora, David Gross, , , | Summary: The representation theory of the Clifford group is playing an increasingly prominent role in quantum information theory, including in such diverse use cases as the construction of protocols for quantum system certification, quantum simulation, and quantum cryptography. In these […]

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Matthew P. A. Fisher, Vedika Khemani, Adam Nahum, Sagar Vijay, | Summary: Quantum circuits — built from local unitary gates and local measurements — are a new playground for quantum many-body physics and a tractable setting to explore universal collective phenomena far-from-equilibrium. These models have […]

Kavli Affiliate: Lars Bildsten | First 5 Authors: Benny T. -H. Tsang, Daniel Kasen, Lars Bildsten, , | Summary: Eruptive mass loss likely produces the energetic outbursts observed from some massive stars before they undergo core-collapse supernovae (CCSNe). The resulting dense circumstellar medium (CSM) may also cause the subsequent SNe to be observed as Type […]
