Universal properties of many-body delocalization transitions
We study the dynamical melting of "hot" one-dimensional many-body localized systems. As disorder is weakened below a critical value these non-thermal quantum glasses melt via a continuous dynamical
Nematic valley ordering in quantum Hall systems
The interplay between quantum Hall ordering and spontaneously broken ``internal'' symmetries in two-dimensional electron systems with spin or pseudospin degrees of freedom gives rise to a variety of
Quantum criticality of hot random spin chains.
It is argued that random-bond Heisenberg chains self-thermalize and that the excited-state entanglement crosses over from volume-law to logarithmic scaling at a length scale that diverges in the Heisenburg limit k→∞.
Glide symmetry breaking and Ising criticality in the quasi-1D magnet CoNb2O6
A microscopic Hamiltonian is proposed that reproduces the entirety of the experimental phenomenology of the quasi-1D Ising magnet CoNb2O6 and gives a unified microscopic explanation of the dispersion of confined states in the ordered phase and quasiparticle breakdown in the polarized phase at high transverse field.
Probing the chiral anomaly with nonlocal transport in three dimensional topological semimetals
Weyl semimetals are three-dimensional crystalline systems where pairs of bands touch at points in momentum space, termed Weyl nodes, that are characterized by a definite topological charge: the
Gigahertz speed operation of epsilon-near-zero silicon photonic modulators
Optical communication systems increasingly require electro-optical modulators that deliver high modulation speeds across a large optical bandwidth with a small device footprint and a CMOS-compatible
Kosterlitz-Thouless scaling at many-body localization phase transitions
We propose a scaling theory for the many-body localization (MBL) phase transition in one dimension, building on the idea that it proceeds via a “quantum avalanche.” We argue that the critical
Featureless and nonfractionalized Mott insulators on the honeycomb lattice at 1/2 site filling
Significance Symmetries are increasingly shown to play various key roles determining the possible phases in condensed matter systems. We study bosonic particles (including electron Cooper pairs)
Charge transport in Weyl semimetals.
The conductivity σ(ω,T) is determined by solving a quantum Boltzmann equation within a "leading log" approximation and finds it to be proportional to T, up to logarithmic factors arising from the flow of couplings.
