Hund’s Rule, Interorbital Hybridization, and High-$T_c$ Superconductivity in the Bilayer Nickelate

Posted by klaurent November 21, 2023UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Xing-Zhou Qu, , , | Summary: Understanding the pairing mechanism in bilayer nickelate superconductors constitutes a fascinating quest. Here we investigate the intriguing interplay between Hund’s rule coupling and interorbital hybridization in a two-orbital model for bilayer nickelates, using a comprehensive tensor network approach: density […]

Hund’s Rule, Interorbital Hybridization, and High-$T_c$ Superconductivity in the Bilayer Nickelate

Posted by dbos November 21, 2023UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Dai-Wei Qu, Xin-Wei Yi, Wei Li, Gang Su | Summary: Understanding the pairing mechanism in bilayer nickelate superconductors constitutes a fascinating quest. Using density matrix renormalization group for $T=0$ and thermal tensor networks for $T>0$ properties, along with density functional theory calculations, we investigate the […]

Roles of Hund’s Rule and Hybridization in the Two-orbital Model for High-$T_c$ Superconductivity in the Bilayer Nickelate

Posted by dbos November 21, 2023UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Dai-Wei Qu, Wei Li, Gang Su, | Summary: The intriguing interplay between the two $e_g$ orbitals in the high-$T_c$ nickelate superconductor La$_3$Ni$_2$O$_7$ is studied via the density matrix renormalization group (DMRG) and finite-$T$ thermal tensor-network calculations. We consider a bilayer $t$-$J$ model that incorporates both […]

A Spatially resolved X-ray Polarization map of the Vela Pulsar Wind Nebula

Posted by dbos November 21, 2023December 4, 2023Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Kuan Liu, Fei Xie, Yi-Han Liu, Chi-Yung Ng, Niccolo’ Bucciantini | Summary: In this paper, we present a full spatially resolved polarization map for the Vela Pulsar Wind Nebula (PWN) observed by IXPE. By employing effective background discrimination techniques, our results show a remarkably high degree […]

Third harmonic generation enhancement and wavefront control using a local high-Q metasurface

Posted by klaurent November 20, 2023Caltech

Kavli Affiliate: Harry Atwater | Summary:High quality factor optical nanostructures provide great opportunity to enhance nonlinear optical processes such as third harmonic generation. However, the field enhancement in these high quality factor structures is typically accompanied by optical mode nonlocality. As a result, the enhancement of nonlinear processes comes at the cost of their local […]

Gene expression in growing cells: A biophysical primer

Posted by dbos November 20, 2023December 4, 2023Harvard

Kavli Affiliate: Ariel Amir | First 5 Authors: Ido Golding, Ariel Amir, , , | Summary: Cell growth and gene expression, essential elements of all living systems, have long been the focus of biophysical interrogation. Advances in single-cell methods have invigorated theoretical studies into these processes. However, until recently, there was little dialog between the […]

A reference genome for the Andean cavefish Trichomycterus rosablanca (Siluriformes, Trichomycteridae): building genomic resources to study evolution in cave environments

Posted by dbos November 20, 2023November 27, 2023Rockefeller

Kavli Affiliate: Erich Jarvis | Authors: Daniel Cadena, Laura Pabon, Carlos DoNascimiento, Linelle Abueg, Tatiana Tiley, Brian O-Toole, Dominic Absolon, Ying Sims, Giulio Formenti, Olivier Fedrigo, Erich Jarvis and Mauricio Torres | Summary: Animals living in caves are of broad relevance to evolutionary biologists interested in understanding the mechanisms underpinning convergent evolution. In the Eastern […]

Magnetic field-temperature competition and quantum criticality in a strange metal

Posted by klaurent November 20, 2023Cornell

Kavli Affiliate: Brad Ramshaw | Summary:Strange metals defy the quasiparticle description of conventional metals, exhibiting a linear in temperature ($T$-linear) resistivity in a broad temperature range. It has become increasingly clear that, together with $T$-linear resistivity, strange metals exhibit a characteristic response in strong magnetic fields, which might point to the quantum critical origin of […]

Transitive and non-transitive subgroups of permutation groups

Posted by dbos November 20, 2023UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Arda Demirhan, Jacob Miller, Yixu Qiu, Thomas J. Tucker, Zheng Zhu | Summary: We treat the problem of finding transitive subgroups G of S_n containing normal subgroups N_1 and N_2, with N_1 transitive and N_2 not transitive, such that G/N_1 is isomorphic G/N_2. We show that such […]
