Cooperativity Leads to Temporally-Correlated Fluctuations in the Bacteriophage Lambda Genetic Switch [PDF]

Frontiers in Plant Science, 2015
Cooperative interactions are widespread in biochemical networks, providing the nonlinear response that underlies behavior such as ultrasensitivity and robust switching.

Fluctuations in strongly correlated electron systems

Results in Physics, 2018
High transition temperature superconductors in cuprates exhibit the charge-density-wave fluctuations and the ferromagnetic time-reversal-symmetry-breaking fluctuation in the polar Kerr rotation experiments. We demonstrate that they share the same root of

Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL

IUCrJ, 2021
Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

A phenomenological model of the X-ray pulse statistics of a high-repetition-rate X-ray free-electron laser

IUCrJ, 2023
Many coherent imaging applications that utilize ultrafast X-ray free-electron laser (XFEL) radiation pulses are highly sensitive to fluctuations in the shot-to-shot statistical properties of the source.

Preferred orientation and its effects on intensity-correlation measurements

IUCrJ, 2022
Intensity-correlation measurements allow access to nanostructural information on a range of ordered and disordered materials beyond traditional pair-correlation methods.

Long-range intra-protein communication can be transmitted by correlated side-chain fluctuations alone. [PDF]

PLoS Computational Biology, 2011
Allosteric regulation is a key component of cellular communication, but the way in which information is passed from one site to another within a folded protein is not often clear.

Critical charge fluctuations and emergent coherence in a strongly correlated excitonic insulator

npj Quantum Materials, 2021
Excitonic insulator is a coherent electronic phase that results from the formation of a macroscopic population of bound particle-hole pairs—excitons. With only a few candidate materials known, the collective excitonic behavior is challenging to observe ...

Observation of electrostatic fluctuations driven by runaway electrons in EAST disruptions

Nuclear Fusion, 2023
Electrostatic fluctuations driven by runaway electrons (REs) have been observed following a thermal quench during Experimental Advanced Superconducting Tokamak–intended disruptions, which are triggered by massive gas injection. Electrostatic fluctuations

Quantum vacuum excitation of a quasi-normal mode in an analog model of black hole spacetime [PDF]

EPJ Web of Conferences, 2022
Vacuum quantum fluctuations near horizons are known to yield correlated emission by the Hawking effect. In this talk, I will explain how a 1 dimensional flow of microcavity polaritons may be engineered to produce an effective curved spacetime with a ...

Strong electron-phonon coupling driven pseudogap modulation and density-wave fluctuations in a correlated polar metal

Nature Communications, 2023
There is tremendous interest in employing collective excitations of the lattice, spin, charge, and orbitals to tune strongly correlated electronic phenomena. We report such an effect in a ruthenate, Ca3Ru2O7, where two phonons with strong electron-phonon
