Redshift Suppression of Nonlinear Scalar Fields in Accelerating FLRW Spacetimes
Mirda Prisma Wijayanto, Emir Syahreza Fadhilla, Ryan Sugihakim +3
We study small--data solutions of a nonlinear scalar field equation on spatially flat --dimensional FLRW spacetimes (). In conformal time the field satisfies a damped…
Fast-forward adiabatic quantum dynamics of XY spin model on three spin system
Iwan Setiawan, Riska Ekawita, Ryan Sugihakim +1
We discussed a method to accelerate an adiabatic quantum dynamics of XY spin model by using the fast-forward method proposed by Masuda and Nakamura. The Accelerated scheme is const…
Bound States of Central Force System in Special Relativity
Iwan Setiawan, Ryan Sugihakim, Bobby Eka Gunara
In this paper we consider the central force problem in the special theory of relativity. We derive the special relativistic version of the Binet equation describing the orbit of a…
Fast-forward approach to adiabatic quantum dynamics of regular spin clusters: nature of geometry-dependent driving interactions
Iwan Setiawan, Bobby Eka Gunara, Sanat Avazbaev +1
The fast forward scheme of adiabatic quantum dynamics is applied to finite regular spin clusters with various geometries and the nature of driving interactions is elucidated. The f…
Fast forward of adiabatic spin dynamics of entangled states
Iwan Setiawan, Bobby Eka Gunara, Shumpei Masuda +1
We develop a scheme of fast forward of adiabatic spin dynamics of quantum entangled states. We settle the quasi-adiabatic dynamics by adding the regularization terms to the origina…
