Observation of end-to-end pumping in a quasiperiodic Fibonacci-type photonic chain
Arnob Kumar Ghosh, Ang Chen, Ashraf El Hassan +3
End-to-end pumps utilizing edge-localized states offer a promising route to operate as connecting buses, supplying efficient and robust connectivity between non-neighboring element…
Topology and energy dependence of Majorana bound states in a photonic cavity
Aksel Kobiałka, Arnob Kumar Ghosh, Rodrigo Arouca +1
Light-matter interaction plays a crucial role in modifying the properties of quantum materials. In this work, we investigate the effect of cavity induced photon fields on a topolog…
Probing Topological Stability with Nonlocal Quantum Geometric Markers
Quentin Marsal, Hui Liu, Emil J. Bergholtz +1
Spatially resolved local quantum geometric markers play a crucial role in the diagnosis of topological phases without long-range translational symmetry, including amorphous systems…
Electric field controlled second-order anomalous Hall effect in altermagnets
Arnob Mukherjee, Biplab Sanyal, Annica M. Black-Schaffer +1
Altermagnets are a recently discovered class of compensated magnets with momentum-dependent spin splittings and unusual transport properties, even without a net magnetization. In t…
Buckling and flat bands in twisted bilayer graphene
Jannes van Poppelen, Annica M. Black-Schaffer
Magic-angle twisted bilayer graphene (TBG) with its flat bands provides a rich platform for exploring emergent electronic orders. Similarly, periodically buckled monolayer graphene…
Laser-induced topological phases in monolayer amorphous carbon
Arnob Kumar Ghosh, Quentin Marsal, Annica M. Black-Schaffer
Driving non-topological materials out of equilibrium using time-periodic perturbations, such as circularly-polarized laser light, is a compelling way to engineer topological phases…
