Multidimensional coherent spectroscopy of correlated lattice systems
Multi-pulse setup
Conventional transient absorption experiments involve two pulses – a pump pulse drives the system into an excited state, while the following probe pulse is used to detect the pump-induced modifications in the sample. The…

Improving PSNR and computational efficiency in orthogonal ghost imaging
We initiate our evaluation process with numerical simulation to compare the image quality produced by the novel approach with the other existing methods. Here, the target object for simulation is an image of \(200\times 200\) pixels with a square…

Strain tuning of optical and thermoelectric properties of monolayer BAs
Optical properties
Figure 1 illustrates the band structure of monolayer BAs along the high symmetric path Γ-M-K-Γ in the Brillouin zone. The results obtained from tight-binding model (shown in blue dashed lines) are compared with those from the…

Critical behavior of Fredenhagen-Marcu string order parameters at topological phase transitions with emergent higher-form symmetries
Toric code model and the FM string order parameter
We consider the toric code model on a square lattice in a field:
$${H}_{{\rm{TC}}}({h}_{x},{h}_{z})=-\sum _{v}{A}_{v}-\sum _{p}{B}_{p}-{h}_{x}\sum _{e}{X}_{e}-{h}_{z}\sum _{e}{Z}_{e},$$

Monitored long-range interacting systems: spin-wave theory for quantum trajectories
Monitored long-range spin systems
We consider a system with N spin-s degrees of freedom on a lattice whose sites are labeled by indices i, j, that is subjected to continuous monitoring. For concreteness, we consider the case of weak monitoring…
