A Universal Operator Growth Hypothesis
Daniel E. Parker, Xiangyu Cao, Alexander Avdoshkin +2
We present a hypothesis for the universal properties of operators evolving under Hamiltonian dynamics in many-body systems. The hypothesis states that successive Lanczos coefficien…
Topologically-Protected Long Edge Coherence Times in Symmetry-Broken Phases
Daniel E. Parker, Romain Vasseur, Thomas Scaffidi
We argue that symmetry-broken phases proximate in phase space to symmetry-protected topological phases can exhibit dynamical signatures of topological physics. This dynamical, symm…
Diagrammatic approach to nonlinear optical response with application to Weyl semimetals
Daniel E. Parker, Takahiro Morimoto, Joseph Orenstein +1
Nonlinear optical responses are a crucial probe of physical systems including periodic solids. In the absence of electron-electron interactions, they are calculable with standard p…
Resonance-enhanced optical nonlinearity in the Weyl semimetal TaAs
Shreyas Patankar, Liang Wu, Baozhu Lu +10
While all media can exhibit first-order conductivity describing current linearly proportional to electric field, , the second-order conductivity, , relating current to…
