Cavity based sensing of antiferromagnetic canting and nonzero-momentum spin waves in a van der Waals cavity-magnon-polariton system
Supriya Mandal, Krishnendu Maji, Lucky N. Kapoor +6
Cavity-magnon-polaritons are hybrid excitations from the interaction between cavity photons and magnons, the quanta of collective spin oscillations. Along with the tunability of th…
Andreev Reflections in NbN/graphene Junctions under Large Magnetic Fields
Da Wang, Evan J. Telford, Avishai Benyamini +7
Hybrid superconductor/graphene (SC/g) junctions are excellent candidates for investigating correlations between Cooper pairs and quantum Hall (QH) edge modes. Experimental studies…
Hall Effect for Dirac Electrons in Graphene Exposed to an Abrikosov Flux Lattice
Jonathan Schirmer, Ravi Kumar, Vivas Bagwe +6
The proposals for realizing exotic particles through coupling of quantum Hall effect to superconductivity involve spatially non-uniform magnetic fields. As a step toward that goal,…
Coplanar cavity for strong coupling between photons and magnons in van der Waals antiferromagnet
Supriya Mandal, Lucky N. Kapoor, Sanat Ghosh +6
We investigate the performance of niobium nitride superconducting coplanar waveguide resonators towards hybrid quantum devices with magnon-photon coupling. We find internal quality…
Inter-Landau-level Andreev Reflection at the Dirac Point in a Graphene Quantum Hall State Coupled to a NbSe2 Superconductor
Manas Ranjan Sahu, Xin Liu, Arup Kumar Paul +4
Superconductivity and quantum Hall effect are distinct states of matter occurring in apparently incompatible physical conditions. Recent theoretical developments suggest that the c…
Andreev reflection near the Dirac point at Graphene - NbSe2 junction
Manas Ranjan Sahu, Pratap Raychaudhuri, Anindya Das
Despite extensive search for about a decade, specular Andreev reflection is only recently realized in bilayer graphene-superconductor interface. However, the evolution from the typ…
Superconductivity in im-miscible Cu-Nb phase separated nano-composite thin films
Pradnya Parab, Vivas Bagwe, Bhagyashree Chalke +3
Superconductivity in granular films is controlled by the grain size and the inter-grain coupling. In a two-component granular system formed by a random mixture of a normal metal (N…
Origin of Matching Effect in Anti-dot Array of Superconducting NbN Thin Films
Sanjeev Kumar, Chandan Kumar, John Jesudasan +4
We investigate the origin of matching effect observed in disordered superconducting NbN thin films with periodic array of holes. In addition to the periodic variation in the electr…
Competing effects of surface phonon softening and quantum size effects on the superconducting properties of nanostructured Pb
Sangita Bose, Charudatta Galande, S. P. Chockalingam +3
The superconducting transition temperature (TC) in nanostructured Pb remains nearly constant as the particle size is reduced from 65 to 7nm, below which size the superconductivity…
Upper critical field in nanostructured Nb: Competing effects of the reduction in density of states and the mean free path
Sangita Bose, Pratap Raychaudhuri, Rajarshi Banerjee +1
We show that the upper critical field in nanometer-sized Nb particles is governed by the changes in the effective Ginzburg-Landau coherence length occurring due to two competing fa…
Size induced metal insulator transition in nanostructured Niobium thin films: Intragranular and intergranular contributions
Sangita Bose, Rajarshi Banerjee, Arda Genc +3
With a reduction in the average grain size in nanostructured films of elemental Nb, we observe a systematic crossover from metallic to weakly-insulating behavior. An analysis of th…
