Valley-Selective Landau-Zener Oscillations in Semi-Dirac p-n Junctions
K. Saha, R. Nandkishore, S. A. Parameswaran
We study transport across p-n junctions of gapped two-dimensional semi-Dirac materials: nodal semimetals whose energy bands disperse quadratically and linearly along distinct cryst…
Eigenstate phase transitions and the emergence of universal dynamics in highly excited states
S. A. Parameswaran, Andrew C. Potter, Romain Vasseur
We review recent advances in understanding the universal scaling properties of non-equilibrium phase transitions in non-ergodic disordered systems. We discuss dynamical critical po…
Non-Fermi glasses: fractionalizing electrons at finite energy density
S. A. Parameswaran, Sarang Gopalakrishnan
Non-Fermi liquids are metals that cannot be adiabatically deformed into free fermion states. We argue for the existence of "non-Fermi glasses," which are phases of interacting diso…
Fractionalizing glide reflections in two-dimensional Z2 topologically ordered phases
SungBin Lee, Michael Hermele, S. A. Parameswaran
We study the fractionalization of space group symmetries in two-dimensional topologically ordered phases. Specifically, we focus on Z2-fractionalized phases in two dimensions whose…
Spin-catalyzed hopping conductivity in disordered strongly interacting quantum wires
S. A. Parameswaran, Sarang Gopalakrishnan
In one-dimensional electronic systems with strong repulsive interactions, charge excitations propagate much faster than spin excitations. Such systems therefore have an intermediat…
