Nonlinear Interferometry for Quantum-Enhanced Measurements of Multiphoton Absorption
Shahram Panahiyan, Carlos Sánchez Muñoz, Maria V. Chekhova +1
Multiphoton absorption is of vital importance in many spectroscopic, microscopic or lithographic applications. However, given that it is an inherently weak process, the detection o…
Two-photon absorption measurements in the presence of single-photon losses
Shahram Panahiyan, Carlos Sánchez Muñoz, Maria V. Chekhova +1
We discuss how two-photon absorption (TPA) of squeezed and coherent states of light can be detected in measurements of the transmitted light fields. Such measurements typically suf…
Unification of topological invariants in Dirac models
Gero von Gersdorff, Shahram Panahiyan, Wei Chen
Topological phases of materials are characterized by topological invariants that are conventionally calculated by different means according to the dimension and symmetry class of t…
Fidelity susceptibility near topological phase transitions in quantum walks
S. Panahiyan, W. Chen, S. Fritzsche
The notion of fidelity susceptibility, introduced within the context of quantum metric tensor, has been an important quantity to characterize the criticality near quantum phase tra…
Toward simulation of topological phenomenas with one-, two- and three-dimensional quantum walks
S. Panahiyan, S. Fritzsche
We study the simulation of the topological phases in three subsequent dimensions with quantum walks. We are mainly focused on the completion of a table for the protocols of the qua…
Controllable simulation of topological phases and edge states with quantum walk
S. Panahiyan, S. Fritzsche
We simulate various topological phenomena in condense matter, such as formation of different topological phases, boundary and edge states, through two types of quantum walk with st…
