Multistate Control of Nonlinear Photocurrents in Optoferroelectrics via phase manipulation of light field
Ali Kazempour, Esmaeil Taghizadeh Sisakht, Mahmut Sait Okyay +3
Ultrafast optical control of ferroelectricity based on short and intense light can be utilized to achieve accurate manipulations of ferroelectric materials, which may pave a basis…
Cost-Effective Methodology for Complex Tuning Searches in HPC: Navigating Interdependencies and Dimensionality
Adrian Perez Dieguez, Min Choi, Mahmut Okyay +3
Tuning searches are pivotal in High-Performance Computing (HPC), addressing complex optimization challenges in computational applications. The complexity arises not only from finel…
Accelerating Quantum Optimal Control of Multi-Qubit Systems with Symmetry-Based Hamiltonian Transformations
Xian Wang, Mahmut Sait Okyay, Anshuman Kumar +1
We present a novel, computationally efficient approach to accelerate quantum optimal control calculations of large multi-qubit systems used in a variety of quantum computing applic…
Velocity-gauge real-time time-dependent density functional tight-binding for large-scale condensed matter systems
Qiang Xu, Mauro Del Ben, Mahmut Sait Okyay +3
We present a new velocity-gauge real-time, time-dependent density functional tight-binding (VG-rtTDDFTB) implementation in the open-source DFTB+ software package (https://dftbplus.…
Tracing out the Berry curvature dipole and multipoles in second harmonic Hall responses of time-reversal symmetric insulators
Mahmut Sait Okyay, Shunsuke Sato, Kunwoo Kim +3
Various nonlinear characteristics of solid states, such as the circular photogalvanic effect of time-reversal symmetric insulators, the quantized photogalvanic effect of Weyl semim…
Identification of the Mott insulating CDW state in 1T-TaS
Dongbin Shin, Nicolas Tancogne-Dejean, Jin Zhang +3
We investigate the low-temperature charge-density-wave (CDW) state of bulk TaS with a fully self-consistent DFT+U approach, over which the controversy has remained unresolved r…
