Three-dimensional Foliated Fractional Quantum Hall Phases
Sahana Das, Navketan Batra, Andrea Kouta Dagnino +4
Foliated topological orders in three dimensions are layered systems in which anyons are free to move within a layer but cannot hop between them. A simple model with such a phase is…
Anyonic analogue of optical Mach-Zehnder interferometer
Navketan Batra, Zezhu Wei, Smitha Vishveshwara +1
Anyonic interferometry is a direct probe of fractional statistics. We propose an interferometry geometry that parallels an optical Mach-Zehnder interferometer and offers several ad…
Excitons in the Fractional Quantum Hall Effect
Naiyuan J. Zhang, Ron Q. Nguyen, Navketan Batra +5
Excitons, Coulomb-driven bound states of electrons and holes, are typically composed of integer charges. However, in bilayer systems influenced by charge fractionalization, a more…
A Bound on Topological Gap from Newton's Laws
Navketan Batra, D. E. Feldman
A striking general bound on the energy gap in topological matter was recently discovered in Ref. [Onishi and Fu, Phys. Rev. X {\bf 14}, 011052 (2024)]. A non-trivial indirect deriv…
Anyonic Mach-Zehnder interferometer on a single edge of a 2D electron gas
Navketan Batra, Zezhu Wei, Smitha Vishveshwara +1
Anyonic Fabry-Pérot and Mach-Zehnder interferometers have been proposed theoretically and implemented experimentally as tools to probe electric charges and statistics of anyons. Th…
Different fractional charges from auto- and cross-correlation noise in quantum Hall states without upstream modes
Navketan Batra, D. E. Feldman
Fractional charges of anyons can be extracted from shot noise in two ways. One can use either the auto-correlation noise of the current in one drain or the cross-correlation noise…
Thermal interferometry of anyons
Zezhu Wei, Navketan Batra, V. F. Mitrović +1
Anyonic interferometry probes the braiding phases of excitations in topologically ordered matter. This technique is well established for charged quasiparticles in the fractional qu…
Pairing symmetries in the Zeeman-coupled extended attractive Hubbard model
Swagatam Nayak, Navketan Batra, Sanjeev Kumar
By introducing the possibility of equal- and opposite-spin pairings concurrently, we show that the extended attractive Hubbard model (EAHM) exhibits rich ground state phase diagram…
Quantum theory of statistical radiation pressure in free space
Navdeep Arya, Navketan Batra, Kinjalk Lochan +1
Light is known to exert radiation pressure on any surface it is incident upon, via the transfer of momentum from the light to the surface. In general, this force is assumed to be p…
Understanding Basic Concepts of Topological Insulators Through Su-Schrieffer-Heeger (SSH) Model
Navketan Batra, Goutam Sheet
Topological insulators are a new class of materials that have attracted significant attention in contemporary condensed matter physics. They are different from the regular insulato…
Topological Transitions in a Model for Proximity Induced Superconductivity
Navketan Batra, Swagatam Nayak, Sanjeev Kumar
Using a prototype model for proximity induced superconductivity on a bilayer square lattice, we show that interlayer tunneling can drive change in topology of the Bogoliubov quasip…
