Diabolical touching point in the magnetic energy levels of topological nodal-line metals
Chong Wang, Zhongyi Zhang, Chen Fang +1
For three-dimensional metals, Landau levels disperse as a function of the magnetic field and the momentum wavenumber parallel to the field. In this two-dimensional parameter space,…
On the wrapped Fukaya category and the loop space of Lagrangians in a Liouville manifold
Zhongyi Zhang
We introduce an map from the cubical chain complex of the based loop space of Lagrangian submanifolds with Legendrian boundary in a Liouville Manifold $C_{*}(Ω_{L} \math…
Constraints on Mediator Coupled to Heavy Quarks from LHC Data
Manuel Drees, Zhongyi Zhang
We apply LHC data to constrain a simplified extension of the Standard Model containing a new spin-1 mediator , which does not couple to first generation quarks, and a spinor dar…
Constraints on from LHC Data
Manuel Drees, Meng Shi, Zhongyi Zhang
In this study, we apply LHC data to constrain the extension of the Standard Model by an anomaly-free gauge group; this model contains a new gauge boson (…
Constraints on a Light Leptophobic Mediator from LEP Data
Manuel Drees, Zhongyi Zhang
We apply data taken at the collider LEP in the 1990's at center-of-mass energy up to 209 GeV to constrain Dark Matter models with a light leptophobic spin-1 mediator .…
