Ultrafast time- and angle-resolved photoemission spectroscopy with widely tunable probe photon energy of 5.3-7.0 eV for investigating dynamics of three-dimensional materials

Posted by klaurent Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Changhua Bao, Haoyuan Zhong, Shaohua Zhou, Runfa Feng, Yuan Wang | Summary: Time- and angle-resolved photoemission spectroscopy (TrARPES) is a powerful technique for capturing the ultrafast dynamics of charge carriers and revealing photo-induced phase transitions in quantum materials. However, the lack of widely tunable probe photon energy, […]

Disordered vector models: from higher spins to incipient strings

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Chi-Ming Chang, Sean Colin-Ellerin, Cheng Peng, Mukund Rangamani, | Summary: We present a one-parameter family of large $N$ disordered models, with and without supersymmetry, in three spacetime dimensions. They interpolate from the critical large $N$ vector model dual to a classical higher spin theory, towards a theory […]

The Early Dark Sector, the Hubble Tension, and the Swampland

Posted by klaurent Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: Evan McDonough, Meng-Xiang Lin, J. Colin Hill, Wayne Hu, Shengjia Zhou | Summary: We consider the interplay of the Early Dark Energy (EDE) model, the Swampland Distance Conjecture (SDC), and cosmological parameter tensions. EDE is a proposed resolution of the Hubble tension relying upon a near-Planckian scalar […]

Cluster cosmology with anisotropic boosts: Validation of a novel forward modeling analysis and application on SDSS redMaPPer clusters

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Youngsoo Park, Tomomi Sunayama, Masahiro Takada, Yosuke Kobayashi, Hironao Miyatake | Summary: We present a novel analysis for cluster cosmology that fully forward models the abundances, weak lensing, and the clustering of galaxy clusters. Our analysis notably includes an empirical model for the anisotropic boosts impacting the […]

Anomalous Josephson Effect in Topological Insulator-Based Josephson Trijunction

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Zhaozheng Lyu, Guang Yang, Bing Li, Yan-Liang Hou | Summary: We studied anomalous Josephson effect (AJE) in Josephson trijunctions fabricated on Bi$_2$Se$_3$, and found that the AJE in T-shaped trijunctions significantly alters the Majorana phase diagram of the trijunctions, when an in-plane magnetic field is […]

Critical Stellar Central Densities Drive Galaxy Quenching in the Nearby Universe

Posted by klaurent Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bingxiao Xu, Yingjie Peng, , , | Summary: We study the structural and environmental dependence of the star formation on the plane of stellar mass versus central core density ($Sigma_{rm 1 kpc}$) in the nearby universe. We study the central galaxies in the sparse environment and find […]

Nonlocal screening dictates the radiative lifetimes of excitations in lead halide perovskites

Posted by Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Yoonjae Park, Amael Obliger, David T. Limmer, , | Summary: We use path integral molecular dynamics simulations and theory to elucidate the interactions between charge carriers, as mediated by a lead halide perovskite lattice. We find that the charge-lattice coupling of MAPbI$_3$ results in a repulsive […]

Systematically Testing Singlet Models for $(g-2)_μ$

Posted by Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Rodolfo Capdevilla, David Curtin, Yonatan Kahn, Gordan Krnjaic, | Summary: We comprehensively study all viable new-physics scenarios that resolve the muon $(g-2)_mu$ anomaly with only Standard Model singlet particles coupled to muons. Since such models are only viable in the MeV — TeV mass range and require […]

Inhomogeneous superconducting states in two weakly linked superconducting ultra thin films

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Gao-Wei Qiu, Yi Zhou, , , | Summary: A sufficiently large parallel magnetic field will generate staggered supercurrent loops and superfluid density wave in two weakly linked superconducting (SC) ultrathin films, resulting in an inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state. The SC order parameter of such an FFLO state […]
