Title: Real-time dynamics of axion particle production due to spontaneous decay of a coherent axion field

Abstract

We show that the coherent axion field spontaneously decays by emitting axion particles via quantum tunneling if axion potential has more than one minimum. By employing the ℏ expansion and mean field approximation, we develop a formalism to trace the real-time dynamics of the axion particle production including its backreaction to the coherent axion field. We also present numerical results for the time evolution of various physical quantities including the strength of the coherent axion field, phase-space density of produced axion particles, energy density, and pressure. Phenomenological implications of our results are also discussed.

Chiral magnetic photocurrent in Dirac and Weyl materials

Journal Article Kaushik, Sahal ; Kharzeev, Dmitri E. ; Philip, Evan John - Physical Review B

Circularly polarized light (CPL) can induce an asymmetry between the number of left- and right-handed chiral quasiparticles in Dirac and Weyl semimetals. Here, we show that if the photoresponse of the material is dominated by chiral quasiparticles, the total chiral charge induced in the material by CPL can be evaluated in a model-independent way through the chiral anomaly. In the presence of an external magnetic field perpendicular to the incident CPL, this allows us to predict the linear density of the induced photocurrent resulting from the chiral magnetic effect. The predicted effect should exist in any kind of Dirac ormore »« less

Giant photocurrent in asymmetric Weyl semimetals from the helical magnetic effect

Journal Article Kharzeev, Dmitri E. ; Kikuchi, Yuta ; Meyer, René ; ... - Physical Review B

We propose a new type of photoresponse induced in asymmetric Weyl semimetals in an external magnetic field. In usual symmetric Weyl semimetals in a magnetic field, the particles and holes produced by an incident light in different Weyl cones have opposite helicities and hence move in opposite directions, canceling each others's contributions to the photocurrent. However this cancelation does not occur if the Weyl semimetal possesses both a broken particle-hole symmetry and a broken spatial inversion symmetry. We call the resulting generation of photocurrent the helical magnetic effect because it is induced by the helicity imbalance in a magnetic field.more »« less

Damping mechanisms for coherent oscillations of axions

Journal Article Unruh, W G ; Wald, R M - Phys. Rev. D; (United States)

It has been proposed that the ''mass turn-on'' of the axion field in the early Universe could have set that field into a large-amplitude coherent oscillation. We give here a general analysis of damping mechanisms for field oscillations of this nature which are operative during an era of ''mass turn-on.'' A thermal-damping mechanism is analyzed in detail. Order-of-magnitude estimates indicate that the mechanism could possibly be important for axions if the mass turn-on rate is very large near the QCD temperature. If part of the mass turn-on occurs in association with a phase transition, a similar damping mechanism due tomore »« less

Large-misalignment mechanism for the formation of compact axion structures: Signatures from the QCD axion to fuzzy dark matter

Journal Article Arvanitaki, Asimina ; Dimopoulos, Savas ; Galanis, Marios ; ... - Physical Review D

Axions are some of the best motivated particles beyond the Standard Model. We show how the attractive self-interactions of dark matter (DM) axions over a broad range of masses, from 10^–22 eV to 10⁷ GeV, can lead to nongravitational growth of density fluctuations and the formation of bound objects. This structure formation enhancement is driven by parametric resonance when the initial field misalignment is large, and it affects axion density perturbations on length scales of order the Hubble horizon when the axion field starts oscillating, deep inside the radiation-dominated era. This effect can turn an otherwise nearly scale-invariant spectrum ofmore »« less

Observation of spontaneous coherence grating transfer in cold cesium atoms

Journal Article Barreiro, S ; Tabosa, J W.R. - Physical Review. A

We report on the direct observation of spontaneous coherence grating transfer between different pairs of Zeeman sublevels belonging to different cesium hyperfine states. Coherent Bragg diffraction is employed as a signature of the transfer mechanism; this spectrum shows a subnatural linewidth. Theoretically we model the observed effect using a tensorial density matrix formalism to describe the light interaction with a pair of degenerate two-level systems coupled by spontaneous emission. The possibility of transferring a short-lived atomic coherence into a long-lived one might be of considerable importance for the growing field of quantum-information processing.
