Kavli Affiliate: Peter W. Graham | First 5 Authors: Robert Bollig, William DeRocco, Peter W. Graham, Hans-Thomas Janka, | Summary: The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting proto-neutron star. If new pseudoscalar degrees of freedom have large […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Raphaël S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]
Kavli Affiliate: N. C. Yeh |Summary:The existence of nontrivial Berry phases associated with two inequivalent valleys in graphene provides interesting opportunities for investigating the valley-projected topological states. Examples of such studies include observation of anomalous quantum Hall effect in monolayer graphene, demonstration of topological zero modes in molecular graphene assembled by scanning tunneling microscopy, and […]
Kavli Affiliate: N. C. Yeh |Summary:Plasma enhanced chemical vapor deposition (PECVD) techniques have been shown to be an efficient method to achieve single-step synthesis of high-quality monolayer graphene (MLG) without the need of active heating. Here we report PECVD-growth of single-crystalline hexagonal bilayer graphene (BLG) flakes and mm-size BLG films with the interlayer twist angle […]
Kavli Affiliate: Scott P. Wakely| First 5 Authors: A. Archer, A. Archer, , , | Summary:The radio source 3C 264, hosted by the giant elliptical galaxy NGC 3862, was observed with VERITAS between February 2017 and May 2019. These deep observations resulted in the discovery of very-high-energy (VHE; E $>100$ GeV) $γ$-ray emission from this […]
Kavli Affiliate: Simeon Hellerman | Summary:We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in $SU(2)$ $mathcalN=2$ SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of the large-R-charge expansion we compute ab initio the dependence of the leading large-$mathcalJ$ behavior on […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Shunsuke Maeda, Domenico Orlando, Susanne Reffert, Masataka Watanabe | Summary: We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in $SU(2)$ $mathcal{N}=2$ SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of […]
Kavli Affiliate: Taizan Watari | Summary:We showed that there is no SU(2) Witten anomaly in a large class of 4d N = 2 supersymmetric Heterotic string compactifications. The consistency conditions we consider are the modularity of the new supersymmetric index, the integrality of BPS indices, and the discrete Peccei-Quinn shift symmetries. We also found an […]
Kavli Affiliate: Nelson Darkwah Oppong| Summary:We investigate the metastable repulsive branch of a mobile impurity coupled to a degenerate Fermi gas via short-range interactions. We show that the quasiparticle lifetime of this repulsive Fermi polaron can be experimentally probed by driving Rabi oscillations between weakly and strongly interacting impurity states. Using a time-dependent variational approach, […]
