Domain Wall Equations, Hessian of Superpotential, and Bogomol'nyi Bounds
Shouxin Chen, Yisong Yang
An important question concerning the classical solutions of the equations of motion arising in quantum field theories at the BPS critical coupling is whether all finite-energy solu…
Light subgraphs in graphs with average degree at most four
Tao Wang
A graph is said to be {\em light} in a family of graphs if at least one member of contains a copy of and there exists an integer $λ(H, \mathfr…
Iso-oriented monolayer α-MoO3(010) films epitaxially grown on SrTiO3(001)
Yingge Du, Guoqiang Li, Erik W. Peterson +7
The ability to synthesis well-ordered two-dimensional materials under ultra-high vacuum and directly characterize them by other techniques in-situ can greatly advance our current u…
Magnetic Impurity Inspired Abelian Higgs Vortices
Xiaosen Han, Yisong Yang
Inspired by magnetic impurity considerations some broad classes of Abelian Higgs and Chern--Simons--Higgs BPS vortex equations are derived and analyzed.
Determination of Gap Solution and Critical Temperature in Doped Graphene Superconductivity
Chenmei Xu, Yisong Yang
It is shown that the gap solution and critical transition temperature are significantly enhanced by doping in a recently developed BCS formalism for graphene superconductivity in s…
Friedmann-Lemaitre Cosmologies via Roulettes and Other Analytic Methods
Shouxin Chen, Gary W. Gibbons, Yisong Yang
In this work a series of methods are developed for understanding the Friedmann equation when it is beyond the reach of the Chebyshev theorem. First it will be demonstrated that eve…
