Dynamical susceptibility of a near-critical non-conserved order parameter and B2g Raman response in Fe-based superconductors
Avraham Klein, Samuel Lederer, Debanjan Chowdhury +2
We analyze the dynamical response of a two-dimensional system of itinerant fermions coupled to a scalar boson , which undergoes a continuous transition towards nematic order wit…
Dynamical susceptibility near a long-wavelength critical point with a nonconserved order parameter
Avraham Klein, Samuel Lederer, Debanjan Chowdhury +2
We study the dynamic response of a two-dimensional system of itinerant fermions in the vicinity of a uniform () Ising nematic quantum critical point of wave symme…
Signatures of fractionalization in spin liquids from interlayer thermal transport
Yochai Werman, Shubhayu Chatterjee, Siddhardh C. Morampudi +1
Quantum spin liquids (QSLs) are intriguing phases of matter possessing fractionalized excitations. Several quasi-two dimensional materials have been proposed as candidate QSLs, but…
Quantum chaos in an electron-phonon bad metal
Yochai Werman, Steven A. Kivelson, Erez Berg
We calculate the scrambling rate and the butterfly velocity associated with the growth of quantum chaos for a solvable large- electron-phonon system. We study a temp…
Transverse fields to tune an Ising-nematic quantum critical transition
Akash V. Maharaj, Elliott W. Rosenberg, Alexander T. Hristov +4
The paradigmatic example of a continuous quantum phase transition is the transverse field Ising ferromagnet. In contrast to classical critical systems, whose properties depend only…
