Imaging phase winding in topological superconductors with a fork-tip Josephson STM
Vladislav Poliakov, Archisman Panigrahi
The complex phase winding in a topological superconductor remains challenging to access by conventional real-space probes. We propose a scheme to probe this winding with a fork-tip…
Projected amorphous topological insulators
Archisman Panigrahi, Bitan Roy
We introduce projected amorphous topological insulators (PATIs) that despite containing only a fraction () of otherwise randomly selected {\it disconnected} sites of a parent cr…
Viscochiral Transport: Chiral Selection of Hydrodynamic Vortices by Berry Curvature
Archisman Panigrahi, Khachatur Nazaryan
We predict a new viscochiral regime of electronic transport in which spatially varying Hall viscosity selects vortical flow patterns. Although uniform Hall viscosity cannot alter i…
Particle-Hole Ghost Interference in Superconductors
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Mirror-assisted optical interference can improve the fidelity of Young's double-slit interference. Here we discuss an electron analogue: particle-hole interference in superconducto…
Tunable viscosity across the BCS-BEC crossover
Yunxiang Liao, Andrey Grankin, Archisman Panigrahi +2
Tunable interactions make ultracold quantum gases a unique platform for exploring hydrodynamic properties in the strongly correlated regime. Of particular interest are turbulent fl…
Valley polarization of chiral excitonic bound states induced by band geometry
Archisman Panigrahi, Daniel Kaplan
Van der Waals (vdW) materials provide a rich platform for exploring the interplay of interactions, topology, and paired-electron phases. We study how the Berry phase reshapes excit…
Strain Response as a Probe of Spinons in Quantum Spin Liquids
Penghao Zhu, Archisman Panigrahi, Leonid Levitov +1
Quantum spin liquids (QSLs) host emergent, fractionalized fermionic excitations that are charge-neutral. Identifying clear experimental signatures of these excitations remains a ce…
Projected branes as platforms for crystalline, superconducting, and higher-order topological phases
Archisman Panigrahi, Bitan Roy
Projected branes are constituted by only a small subset of sites of a higher-dimensional crystal, otherwise placed on a hyperplane oriented at an irrational or a rational slope the…
Tomographic imaging of superconducting order using particle-hole interference
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Superconducting phases with exotic symmetries that differ from the underlying crystalline lattice are at the focus of superconductivity research. Yet, despite intense interest, det…
Non-Fermi Liquids from Subsystem Symmetry Breaking in van der Waals Multilayers
Archisman Panigrahi, Ajesh Kumar
We investigate the spontaneous breaking of subsystem symmetry in a stack of two-dimensional Fermi liquid metals, each maintaining a subsystem number conservation symmetry, driven b…
Spin chirality and fermion stirring in topological bands
Archisman Panigrahi, Vladislav Poliakov, Zhiyu Dong +1
We demonstrate that in metals, both normal and superconducting, orbital currents present in the ground state when time reversal symmetry (TRS) is broken, generate spin chirality. N…
Fluctuating magnetism and Pomeranchuk effect in multilayer graphene
Ludwig Holleis, Tian Xie, Siyuan Xu +9
Magnetism typically arises from the effect of exchange interactions on highly localized fermionic wave functions in f- and d-atomic orbitals. In rhombohedral multilayer graphene (R…
Spin-orbit proximity in MoS/bilayer graphene heterostructures
M. Masseroni, M. Gull, A. Panigrahi +11
Van der Waals heterostructures provide a versatile platform for tailoring electronic properties through the integration of two-dimensional materials. Among these combinations, the…
Signatures of electronic ordering in transport in graphene flat bands
Archisman Panigrahi, Leonid Levitov
Recently, a wide family of electronic orders was unveiled in graphene flat bands, such as spin- and valley-polarized phases as well as nematic momentum-polarized phases, stabilized…
Projected Topological Branes
Archisman Panigrahi, Vladimir Juricic, Bitan Roy
Nature harbors crystals of dimensionality () only up to three. Here we introduce the notion of \emph{projected topological branes} (PTBs): Lower-dimensional branes embedded in h…
Energy magnetization and transport in systems with a non-zero Berry curvature in a magnetic field
Archisman Panigrahi, Subroto Mukerjee
We demonstrate that the well-known expression for the charge magnetization of a sample with a non-zero Berry curvature can be obtained by demanding that the Einstein relation holds…
Non-Hermitian dislocation modes: Stability and melting across exceptional points
Archisman Panigrahi, Roderich Moessner, Bitan Roy
The traditional bulk-boundary correspondence assuring robust gapless modes at the edges and surfaces of insulating and nodal topological materials gets masked in non-Hermitian (NH)…
