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…
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…
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…
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…
