Floquet states and optical conductivity of an irradiated two dimensional topological insulator
S. Sajad Dabiri, H. Cheraghchi, A. Sadeghi
We study the topology of the Floquet states and time-averaged optical conductivity of the lattice model of a thin topological insulator subject to a circularly polarized light usin…
Theory of nonlinear optical response
Amin Maleki Sheikhabadi, Zahra Bagheri, Ali Sadeghi
We present a general formalism for investigating the second-order optical response of solids to an electric field in weakly disordered crystals with arbitrarily complicated band st…
Light-induced topological phases in thin films of magnetically doped topological insulators
S. Sajad Dabiri, Hosein Cheraghchi, Ali Sadeghi
We study the photon-dressed electronic band structure of topological insulator thin films which could be also doped doped by magnetic impurities in response to an off-resonance tim…
Magnetoelastic coupling enabled tunability of magnon spin current generation in 2D antiferromagnets
Nasim Bazazzadeh, Mohammad Hamdi, Sungjoon Park +3
We theoretically investigate the magnetoelastic coupling (MEC) and its effect on magnon transport in two-dimensional antiferromagnets with a honeycomb lattice. MEC coeffcient along…
Electrical and optical properties of MoS,MoO(MoSO)/RGO heterostructure
S. Erfanifam, L. Jamilpanah, P. Sangpour +8
We report on transport properties of the controllable large area MoSO/Reduced graphene oxide(RGO) heterostructures electrodeposited on FTO substrates and its comparision with theor…
A fingerprint based metric for measuring similarities of crystalline structures
Li Zhu, Maximilian Amsler, Tobias Fuhrer +8
Measuring similarities/dissimilarities between atomic structures is important for the exploration of potential energy landscapes. However, the cell vectors together with the coordi…
Glassy clusters: Relations between their dynamics and characteristic features of their energy landscape
Sandip De, Bastian Schaefer, Ali Sadeghi +3
Based on a recently introduced metric for measuring distances between configurations, we in- troduce distance-energy (DE) plots to characterize the potential energy surface (PES) o…
Boron aggregation in the ground states of boron-carbon fullerenes
Stephan Mohr, Pascal Pochet, Maximilian Amsler +4
We present novel structural motifs for boron-carbon nano-cages of the stochiometries B12C48 and B12C50, based on first principle calculations. These configurations are distinct fro…
Metrics for measuring distances in configuration spaces
Ali Sadeghi, S. Alireza Ghasemi, Bastian Schaefer +3
In order to characterize molecular structures we introduce configurational fingerprint vectors which are counterparts of quantities used experimentally to identify structures. The…
Norm-conserving pseudopotentials with chemical accuracy compared to all-electron calculations
Alexander Willand, Yaroslav O. Kvashnin, Luigi Genovese +5
By adding a non-linear core correction to the well established Dual Space Gaussian type pseudopotentials for the chemical elements up to the third period, we construct improved pse…
A Multi-scale Approach for Simulations of Kelvin Probe Force Microscopy with Atomic Resolution
Ali Sadeghi, Alexis Baratoff, S. Alireza Ghasemi +4
The distance dependence and atomic-scale contrast observed in nominal contact potential difference (CPD) signals recorded by KPFM on surfaces of insulating and semiconducting sampl…
