Symmetry-protected topological order identified via Gutzwiller-guided density-matrix-renormalization-group: $mathrm{SO}(n)$ spin chains

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Pei-Yuan Cai, Hui-Ke Jin, Yi Zhou, , | Summary: We present a comprehensive study of topological phases in the SO($n$) spin chains using a combination of analytical parton construction and numerical techniques. For even $n=2l$, we identify a novel SPT$^2$ phase characterized by two distinct topological sectors, […]

Superconducting quantum oscillations and anomalous negative magnetoresistance in a honeycomb nanopatterned oxide interface superconductor

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yishuai Wang, Siyuan Hong, Wenze Pan, Yi Zhou, Yanwu Xie | Summary: The extremely low superfluid density and unprecedented tunability of oxide interface superconductors provide an ideal platform for studying fluctuations in two-dimensional superconductors. In this work, we have fabricated a LaAlO3/KTaO3 interface superconductor patterned with a […]

Massive Black Hole Seed Formation in Strong X-ray Environments at High Redshift

Posted by dbos Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kazutaka Kimura, Kohei Inayoshi, Kazuyuki Omukai, , | Summary: Direct collapse of pristine gas in early galaxies is a promissing pathway for forming supermassive black holes (BHs) powering active galactic nuclei (AGNs) at the epoch of reionization (EoR). This seeding mechanism requires suppression of molecular hydrogen (H$_2$) […]

Measuring Casimir Force Across a Superconducting Transition

Posted by dbos Delft

Kavli Affiliate: Sander Otte | First 5 Authors: Minxing Xu, Robbie J. G. Elbertse, Ata Keşkekler, Giuseppe Bimonte, Jinwon Lee | Summary: The Casimir effect and superconductivity are foundational quantum phenomena whose interaction remains an open question in physics. How Casimir forces behave across a superconducting transition remains unresolved, owing to the experimental difficulty of […]

Do We Know How to Model Reionization?

Posted by dbos Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I compare the power spectra of the radiation fields from two recent sets of fully-coupled simulations that model cosmic reionization: "Cosmic Reionization On Computers" (CROC) and "Thesan". While both simulations have similar power spectra of the radiation sources, […]

Quantum geometry from the Moyal product: quantum kinetic equation and non-linear response

Posted by dbos UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Xiaoyang Huang, Lucile Savary, Leon Balents, | Summary: We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-diagonalize the dynamics. Expanding to the second order in gradients, which is beyond […]

Cosmogenic Neutrino Point Source and KM3-230213A

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Qinyuan Zhang, Tian-Qi Huang, Zhuo Li, , | Summary: Cosmogenic neutrinos (CNs) are produced by ultra-high energy cosmic rays (UHECRs) interacting with cosmic background radiation. We investigated the properties of CN point/extended sources, i.e, the neutrino spectrum, and angular profile as functions of time, by assuming that […]
