Heavy fermion quantum criticality.
During the last few years, investigations of rare-earth materials have made clear that heavy fermion quantum criticality exhibits novel physics not fully understood. In this work, we write for the first time the effective action describing the low energy physics of the system. The f fermions are replaced by a dynamical scalar field whose nonzero expected value corresponds to the heavy fermion p...
متن کاملQuantum Hair *
A black hole can carry “quantum hair” that, while undetectable classically, can influence quantum physics outside the event horizon. The effect of quantum hair on black hole thermodynamics is computed here, in a particular field-theoretic model. to be exhaustive, but it will demonstrate that quantum hair can exist, and that it can have dramatic and computable effects on the thermodynamic behavi...
متن کاملFermion-fermion scattering in quantum field theory with superconducting circuits.
We propose an analog-digital quantum simulation of fermion-fermion scattering mediated by a continuum of bosonic modes within a circuit quantum electrodynamics scenario. This quantum technology naturally provides strong coupling of superconducting qubits with a continuum of electromagnetic modes in an open transmission line. In this way, we propose qubits to efficiently simulate fermionic modes...
متن کاملClassical simulation of noninteracting-fermion quantum circuits
We show that a class of quantum computations that was recently shown to be efficiently simulatable on a classical computer by Valiant [?] corresponds to a physical model of noninteracting fermions in one dimension. We give an alternative proof of his result using the language of fermions and extend the result to noninteracting fermions with arbitrary pairwise interactions, where gates can be co...
