Non-Hermitian quantum dynamics and entanglement of coupled nonlinear resonators
Evren Karakaya, Ferdi Altintas, Kaan Güven +1
We consider a generalization of recently proposed non-Hermitian model for resonant cavities coupled by a chiral mirror by taking into account number non-conservation and nonlinear…
-Surfaces with Arbitrary Topology in Hyperbolic 3-Space
Baris Coskunuzer
In this paper, we show that any open orientable surface S can be properly embedded in H^3 as a minimizing H-surface for any 0<=H<1. We obtained this result by proving a version of…
A Dynamical Formulation of One-Dimensional Scattering Theory and Its Applications in Optics
Ali Mostafazadeh
We develop a dynamical formulation of one-dimensional scattering theory where the reflection and transmission amplitudes for a general, possibly complex and energy-dependent, scatt…
Accelerating anisotropic cosmologies in Brans-Dicke gravity coupled to a mass-varying vector field
Ozgur Akarsu, Tekin Dereli, Neslihan Oflaz
The field equations of Brans-Dicke gravity coupled to a mass-varying vector field are derived. Anisotropic cosmological solutions with a locally rotationally symmetric Bianchi type…
Transfer Matrices as Non-Unitary S-Matrices, Multimode Unidirectional Invisibility, and Perturbative Inverse Scattering
Ali Mostafazadeh
We show that in one dimension the transfer matrix M of any scattering potential v coincides with the S-matrix of an associated time-dependent non-Hermitian 2 x 2 matrix Hamiltonian…
Mode-coupling points to functionally important residues in Myosin II
Onur Varol, Deniz Yuret, Burak Erman +1
Relevance of mode coupling to energy/information transfer during protein function, particularly in the context of allosteric interactions is widely accepted. However, existing evid…
