Non-Hermitian topology in driven-dissipative systems: correspondence with quantum correlations and a resource for entanglement
Niladri Chakraborty, Clara C. Wanjura
Directional amplification, in which signals are amplified selectively depending on their propagation direction, is a key resource for quantum information processing and stands in o…
Unifying framework for non-Hermitian and Hermitian topology in driven-dissipative systems
Clara C. Wanjura, Andreas Nunnenkamp
Recently, a one-to-one correspondence between non-trivial non-Hermitian topology and directional amplification has been demonstrated, theoretically and experimentally, for the case…
Quadrature nonreciprocity: unidirectional bosonic transmission without breaking time-reversal symmetry
Clara C. Wanjura, Jesse J. Slim, Javier del Pino +3
Nonreciprocity means that the transmission of a signal depends on its direction of propagation. Despite vastly different platforms and underlying working principles, the realisatio…
Correspondence between non-Hermitian topology and directional amplification in the presence of disorder
Clara C. Wanjura, Matteo Brunelli, Andreas Nunnenkamp
In order for non-Hermitian (NH) topological effects to be relevant for practical applications, it is necessary to study disordered systems. In the absence of disorder, certain driv…
Topological framework for directional amplification in driven-dissipative cavity arrays
Clara C. Wanjura, Matteo Brunelli, Andreas Nunnenkamp
Directional amplification, in which signals are selectively amplified depending on their propagation direction, has attracted much attention as key resource for applications, inclu…
