Role of Fe intercalation on the electronic correlation in resistively switchable antiferromagnet Fe$_x$NbS$_2$

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Wenxin Li, Wenxin Li, , , | Summary: Among the family of intercalated transition-metal dichalcogenides (TMDs), Fe$_x$NbS$_2$ is found to possess unique current-induced resistive switching behaviors, tunable antiferromagnetic states, and a commensurate charge order, all of which are tied to a critical Fe doping of $x_c$ […]

Deconfined Quantum Critical Point in Quantum Hall Bilayers

Kavli Affiliate: Zheng Zhu | First 5 Authors: Guangyu Yu, Guangyu Yu, , , | Summary: Deconfined quantum critical points (DQCPs) represent an unconventional class of quantum criticality beyond the Landau-Ginzburg-Wilson-Fisher paradigm. Nevertheless, both their theoretical identification and experimental realization remain challenging. Here we report compelling evidence of a DQCP in quantum Hall bilayers with […]

Octupole-driven spin-transfer torque switching of all-antiferromagnetic tunnel junctions

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Jaimin Kang, Jaimin Kang, , , | Summary: Magnetic tunnel junctions (MTJs) based on ferromagnets are canonical devices in spintronics, with wide-ranging applications in data storage, computing, and sensing. They simultaneously exhibit mechanisms for electrical detection of magnetic order through the tunneling magnetoresistance (TMR) effect, and […]

On anomalies and fermionic unitary operators

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Masaki Okada, Masaki Okada, , , | Summary: We point out that fermionic unitary operators which anticommute among themselves appear in various situations in quantum field theories with anomalies in the Hamiltonian formalism. To illustrate, we give multiple derivations of the fact that position-dependent $U(1)$ transformations of […]

Initial results of the TRIUMF ultracold advanced neutron source

Kavli Affiliate: T. Higuchi | First 5 Authors: B. Algohi, B. Algohi, , , | Summary: We report the first results on ultracold neutron production from a new spallation-driven superfluid $^4$He (He-II) source at TRIUMF, which is being prepared for a new, precise measurement of the neutron electric dipole moment. A total of $(9.3 pm […]

Long-range inhibitory axons from medial entorhinal cortex target lateral entorhinal neurons projecting to the hippocampus

Kavli Affiliate: Menno Witter | Authors: Eirik S. Nilssen, Bente Jacobsen, Thanh P. Doan, Paulo J.B. Girao and Menno P. Witter | Summary: ABSTRACT The functionally different lateral entorhinal cortex (LEC) and medial entorhinal cortex (MEC) are strongly interconnected. The role of this interconnectivity in view of their functional differences is not known. Here we […]

Updated bounds on ultra-light dark matter from the tiniest galaxies

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Simon May, Simon May, , , | Summary: The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to $m > 3 times 10^-19,mathrmeV$. This constraint, which excludes the "fuzzy" range of ultra-light dark matter from comprising all of the DM, […]

Topological Chiral Superconductivity in the Triangular-Lattice Hofstadter-Hubbard Model

Kavli Affiliate: Leon Balents | First 5 Authors: Feng Chen, Feng Chen, , , | Summary: Moir’e materials provide exciting platforms for studying the interplay of strong electronic correlation and large magnetic flux effects. We study the lightly doped Hofstadter-Hubbard model on a triangular lattice through large-scale density matrix renormalization group and determinantal quantum Monte […]

Coupling of a nuclear transition to a Surface Acoustic Wave

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Albert Nazeeri, Albert Nazeeri, , , | Summary: Mechanical modulation of recoilless nuclear transitions allows the dynamic control of gamma-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate such control by coupling a film […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Reena Chaudhary, Reena Chaudhary, , , | Summary: We investigate the origin of intervening cool MgII absorption detected in the spectra of background quasars and the nature of associated galaxies across a broad redshift range of $0.3 le z le 1.6$. Using nebular [O II] $lambdalambda$3727,3729 […]
