Diagnosing the origin of quantum oscillation beating in graphene
Akash Adhikary, Sunit Das, Divya Sahani +2
Magnetic quantum oscillations are usually periodic in inverse magnetic field, and their amplitude can show beating when two nearby frequencies interfere. In graphene-based hexagona…
Quantum Transport Spectroscopy of Pseudomagnetic Field in Graphene
Divya Sahani, Sunit Das, Kenji Watanabe +3
Nonuniform strain in graphene acts as a valley-dependent gauge field, generating pseudomagnetic fields (PMFs) that mimic real magnetic fields but preserve global time-reversal symm…
Odd-parity longitudinal magnetoconductivity in time-reversal symmetry broken materials
Sunit Das, Akash Adhikary, Divya Sahani +2
Magnetotransport measurements are a sensitive probe of symmetry and electronic structure in quantum materials. While conventional metals exhibit longitudinal magnetoconductivity th…
Giant gate-controlled room temperature odd-parity magnetoresistance in magnetized bilayer graphene
Divya Sahani, Sunit Das, Kenji Watanabe +3
Magnetotransport measurements are crucial for understanding the Fermi surface properties, magnetism, and topology in quantum materials. Here, we report the discovery of giant room…
Universality of Quantum Phase Transitions in the Integer and Fractional Quantum Hall Regimes
Simrandeep Kaur, Tanima Chanda, Kazi Rafsanjani Amin +7
Fractional quantum Hall (FQH) phases emerge due to strong electronic interactions and are characterized by anyonic quasiparticles, each distinguished by unique topological paramete…
Observation of time-reversal symmetric Hall effect in graphene-WSe2 heterostructures at room temperature
Priya Tiwari, Divya Sahani, Atasi Chakraborty +5
In this letter, we provide experimental evidence of the time-reversal symmetric Hall effect in a mesoscopic system, namely high-mobility graphene/WSe heterostructures. This lin…
Transition from three- to two-dimensional Ising superconductivity in few-layer NbSe2 by proximity effect from van der Waals heterostacking
Prakiran Baidya, Divya Sahani, Hemanta Kumar Kundu +7
We report the experimental observation of Ising superconductivity in 3-dimensional NbSe2 stacked with single-layer MoS2. The angular dependence of the upper critical magnetic field…
