Emergence of two-fold non-Hermitian spectral topology through synthetic spin engineering
Ronika Sarkar, Ayan Banerjee, Awadhesh Narayan
The union of topology and non-Hermiticity has led to the unveiling of many intriguing phenomena. We introduce a synthetic spin-engineered model belonging to symmetry class AI, whic…
Wormholes and energy conditions in gravity
Ayan Banerjee, Takol Tangphati, Anirudh Pradhan
We explore the existence of wormholes in the context of gravity. The theory is a curvature-matter coupled modified gravity that depends on an arbitrary function o…
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…
The criteria of the anisotropic quark star models in Rastall gravity
Takol Tangphati, Ayan Banerjee, Sudan Hansraj +1
Quark stars are terrestrial laboratories to study fundamental physics at ultrahigh densities and temperatures. In this work, we investigate the internal structure and the physical…
Charged quark stars in gravity
Juan M. Z. Pretel, Takol Tangphati, Ayan Banerjee +1
Recent advances in nuclear theory combined with new astrophysical observations have led to the need for specific theoretical models that actually apply to phenomena on dense-matter…
The Mass-Radius relation for Quark Stars in Energy-Momentum Squared Gravity
Takol Tangphati, Indrani Karar, Ayan Banerjee +1
We study the structure of quark stars (QSs) adopting homogeneously confined matter inside the star with a 3-flavor neutral charge and a fixed strange quark mass . We explore t…
