Exceptional point in a trimer chain of oscillators with a quadratic driving
M Shoufie Ukhtary, Albert Andersen, Donny Dwiputra +1
Exceptional points of a dissipative chain of three coupled oscillators (trimer), which is driven by quadratic photon, are investigated. The exceptional points emerge from the coale…
pyBoLaNO: A Python symbolic package for normal ordering involving bosonic ladder operators
Hendry M. Lim, Donny Dwiputra, M. Shoufie Ukhtary +1
We present pyBoLaNO, a Python symbolic package based on SymPy to quickly normal-order (Wick-order) any polynomial in bosonic ladder operators. By extension, this package offers the…
Hyperbolic enhancement of a quantum battery
C. A. Downing, M. S. Ukhtary
A quantum system which can store energy, and from which one can extract useful work, is known as a quantum battery. Such a device raises interesting issues surrounding how quantum…
Energetics of a pulsed quantum battery
C. A. Downing, M. S. Ukhtary
The challenge of storing energy efficiently and sustainably is highly prominent within modern scientific investigations. Due to the ongoing trend of miniaturization, the design of…
High-performance Kerr quantum battery
Muhammad Shoufie Ukhtary, Ahmad R. T. Nugraha, Adam B. Cahaya +2
We propose and investigate the performance of a hybrid quantum battery, the so-called Kerr quantum battery, which consists of two interacting quantum oscillators, i.e., the charger…
Long-lived qubit entanglement by surface plasmon polaritons in a Weyl semimetal
M Shoufie Ukhtary, Eddwi H. Hasdeo, Andriyan B. Suksmono +1
We investigate spontaneous entanglement of two qubits mediated by nonreciprocal surface plasmon polaritons (SPPs) in a Weyl semimetal. In the absence of external magnetic fields, t…
Justification for zeta function regularization
F. R. Pratama, M. Shoufie Ukhtary, Riichiro Saito
Using the fact that a finite sum of power series are given by the difference between two zeta functions, we justify the usage of the zeta function with a negative variable in physi…
Magnetizations and de Haas-van Alphen oscillations in massive Dirac fermions
F. R. Pratama, M. Shoufie Ukhtary, Riichiro Saito
We theoretically study magnetic field, temperature, and energy band-gap dependences of magnetizations in the Dirac fermions. We use the zeta function regularization to obtain analy…
Intersubband plasmon excitations in doped carbon nanotubes
Daria Satco, Ahmad R. T. Nugraha, M. Shoufie Ukhtary +3
We theoretically investigate intersubband plasmon excitations in doped single wall carbon nanotubes (SWNTs) by examining the dependence of plasmon frequency on the nanotube diamete…
Hidden symmetries in -layer dielectric stacks
Haihao Liu, M. Shoufie Ukhtary, Riichiro Saito
The optical properties of a multilayer system of dielectric media with arbitrary layers is investigated. Each layer is one of two dielectric media, with thickness one-quarter t…
Broadband Transverse Electric Surface Wave in Silicene
M. Shoufie Ukhtary, Ahmad R. T. Nugraha, Eddwi H. Hasdeo +1
Transverse electric (TE) surface wave in silicine is theoretically investigated. The TE surface wave in silicene is found to exhibit better characteristics compared with that in gr…
