Non-Hermitian Topological Phases: Principles and Prospects
Ayan Banerjee, Ronika Sarkar, Soumi Dey +1
The synergy between non-Hermitian concepts and topological ideas have led to very fruitful activity in the recent years. Their interplay has resulted in a wide variety of new non-H…
A new class of solutions to the van Dantzig problem, the Lee-Yang property, and the Riemann hypothesis
T. Konstantopoulos, P. Patie, R. Sarkar
The purpose of this paper is to carry out an in-depth analysis of the intriguing van Dantzig problem which consists on characterizing the set of analytic characteristi…
Non-Hermiticity induced Exceptional Points and Skin Effect in the Dice-Haldane Model
Ronika Sarkar, Arka Bandyopadhyay, Awadhesh Narayan
The interplay of topology and non-Hermiticity has led to diverse, exciting manifestations in a plethora of systems. In this work, we systematically investigate the role of non-Herm…
Interplay of Disorder and Point-Gap Topology: Chiral Modes, Localization and Non-Hermitian Anderson Skin Effect in One Dimension
Ronika Sarkar, Suraj S. Hegde, Awadhesh Narayan
Symmetry-protected spectral topology in non-Hermitian systems has interesting manifestations such as dynamically anomalous chiral currents and skin effect. We study the interplay b…
