Non-Hermitian multimode interferometry
Subhajyoti Bid, Henning Schomerus
Interferometers form a cornerstone of precision measurement, leveraging wave superposition and phase coherence to convert minute physical perturbations into measurable intensity va…
Exceptionally deficient topological square-root insulators
Subhajyoti Bid, Henning Schomerus
One of the most surprising features of effectively non-Hermitian physical systems is their potential to exhibit a striking nonlinear response and fragility to small perturbations.…
Fragmented exceptional points and their bulk and edge realizations in lattice models
Subhajyoti Bid, Henning Schomerus
Exceptional points (EPs) are spectral defects displayed by non-Hermitian systems in which multiple degenerate eigenvalues share a single eigenvector. This distinctive feature makes…
Uniform response theory of non-Hermitian systems: Non-Hermitian physics beyond the exceptional point
Subhajyoti Bid, Henning Schomerus
Non-Hermitian systems display remarkable response effects that reflect a variety of distinct spectral scenarios, such as exceptional points where the eigensystem becomes defective.…
Floquet Exceptional Topological Insulator
Gaurab Kumar Dash, Subhajyoti Bid, Manisha Thakurathi
We propose a novel way of modulating exceptional topology by implementing Floquet engineering in non-hermitian (NH) systems. We introduce Floquet exceptional topological insulator…
Non-Hermitian higher-Order Weyl semimetal with surface diabolic points
Subhajyoti Bid, Gaurab Kumar Dash, Manisha Thakurathi
Higher-order topology in non-Hermitian (NH) systems has recently become one of the most promising and rapidly developing fields in condensed matter physics. Many distinct phases th…
Topological properties of a class of Su-Schrieffer-Heeger variants
Subhajyoti Bid, Arunava Chakrabarti
We investigate the edge states and the topological phase transitions in a class of tight binding lattices in one dimension where a Su-Schrieffer-Heeger (SSH) model exists in disgui…
