Parametrically driven nonlinear Dirac equation with arbitrary nonlinearity
Fred Cooper, Avinash Khare, Niurka R. Quintero +3
The damped and parametrically driven nonlinear Dirac equation with arbitrary nonlinearity parameter is analyzed, when the external force is periodic in space and given by $f(x)…
Extreme Nonreciprocity with Spatio-Temporally Modulated Metasurfaces
Andrew E. Cardin, Sinhara R. Silva, Shai. R. Vardeny +7
Emerging photonic functionalities are mostly governed by the fundamental principle of Lorentz reciprocity. Lifting the constraints imposed by this principle could circumvent delete…
Quantum Electron Transport in Degenerate Donor-Acceptor Systems
Marco Merkli, Gennady P. Berman, Avadh Saxena
We develop a mathematically rigorous theory for the quantum transfer processes in degenerate donor-acceptor dimers in contact with a thermal environment. We calculate explicitly th…
Logarithmic Potential with Super-Super-Exponential Kink Profiles and Tails
Avinash Khare, Avadh Saxena
We consider a novel one dimensional model of a logarithmic potential which has super-super-exponential kink profiles as well as kink tails. We provide analytic kink solutions of th…
Wide Class of Logarithmic Potentials with Power-Tower Kink Tails
Avinash Khare, Avadh Saxena
We present a wide class of potentials which admit kinks and corresponding mirror kinks with either a power law or an exponential tail at the two extreme ends and a power-tower form…
Noise amplification at spin-glass bottlenecks of quantum annealing: a solvable model
David Roberts, Lukasz Cincio, Avadh Saxena +2
To gain better insight into the complexity theory of quantum annealing, we propose and solve a class of spin systems which contain bottlenecks of the kind expected to dominate the…
A model field theory with potential: Kinks with super-exponential profiles
Pradeep Kumar, Avinash Khare, Avadh Saxena
We study a (1+1)-dimensional field theory based on potential. There are three degenerate minima at and . There are novel, asymmetric kink solutions of t…
Superconductivity in Graphene Induced by the Rotated Layer
D. Schmeltzer
Recent discoveries in graphene bilayers revealed that when one of the layers is rotated, superconductivity emerges. We provide an explanation for this phenomenon . We find that due…
Kelvin modes of a skyrmion line in chiral magnets and the associated magnon transport
Shi-Zeng Lin, Jian-Xin Zhu, Avadh Saxena
Magnetic skyrmions in bulk crystals are line-like topologically protected spin textures. They allow for the propagation of magnons along the skyrmion line but are localized inside…
