Wakes from Companion Interactions in Type Ia Supernovae Nebular Emission Line Profiles

Kavli Affiliate: Lars Bildsten | First 5 Authors: Kathlynn Simotas, Kathlynn Simotas, , , | Summary: Thermonuclear supernovae (SNe) are the result of the nuclear transformation of carbon/oxygen (C/O) white dwarfs (WDs) to the radioactive element $^56mathrmNi$ and intermediate mass elements (IMEs) like Ca, Ar, etc. Most progenitor scenarios involve a companion star which donates […]

Spin-charge bound states and emerging fermions in a quantum spin liquid

Kavli Affiliate: Leon Balents | First 5 Authors: Jens H. Nyhegn, Jens H. Nyhegn, , , | Summary: The complex interplay between charge and spin dynamics lies at the heart of strongly correlated quantum materials, and it is a fundamental topic in basic research with far reaching technological perspectives. We explore in this paper the […]

Increasing single-photon production with cavity-QED

Kavli Affiliate: John E. Bowers | First 5 Authors: Chen Shang, Weng W. Chow, Galan Moody, John E. Bowers, | Summary: A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to […]

Emergent magnetism and spin liquids in an extended Hubbard description of moiré bilayers

Kavli Affiliate: Leon Balents | First 5 Authors: Zhenhao Song, Urban F. P. Seifert, Leon Balents, Hong-Chen Jiang, | Summary: Motivated by twisted transition metal dichalcogenides (TMDs), we study an extended Hubbard model with both on-site and off-site repulsive interactions, in which Mott insulating states with concomitant charge order occur at fractional fillings. To resolve […]

Gyrotropic magnetic effect in metallic chiral magnets

Kavli Affiliate: Leon Balents | First 5 Authors: Nisarga Paul, Takamori Park, Jung Hoon Han, Leon Balents, | Summary: We study the gyrotropic magnetic effect (GME), the low-frequency limit of optical gyrotropy, in metals and semimetals coupled to chiral spin textures. In these systems, the chiral spin texture which lacks inversion symmetry can imprint itself […]

Thirty-six officers, artisanally entangled

Kavli Affiliate: David Gross | First 5 Authors: David Gross, Paulina Goedicke, , , | Summary: A perfect tensor of order $d$ is a state of four $d$-level systems that is maximally entangled under any bipartition. These objects have attracted considerable attention in quantum information and many-body theory. Perfect tensors generalize the combinatorial notion of […]

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

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 […]

Identifying Instabilities with Quantum Geometry in Flat Band Systems

Kavli Affiliate: Leon Balents | First 5 Authors: Jia-Xin Zhang, Wen O. Wang, Leon Balents, Lucile Savary, | Summary: The absence of a well-defined Fermi surface in flat-band systems challenges the conventional understanding of instabilities toward Landau order based on nesting. We investigate the existence of an intrinsic nesting structure encoded in the band geometry […]
