Excitonic model of track registration of energetic heavy ions in insulators [PDF]
, 1998 The consequence of generation of dense electronic excitation along the paths of energetic heavy ions is discussed, emphasizing the fates of electron-hole pairs.

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Trapped modes in a waveguide with a long obstacle [PDF]
, 2000 Consider an infinite two-dimensional acoustic waveguide containing a long rectangular obstacle placed symmetrically with respect to the centreline. We search for trapped modes, i.e.

Energy transport in trapped ion chains
New Journal of Physics, 2014 We experimentally study energy transport in chains of trapped ions. We use a pulsed excitation scheme to rapidly add energy to the local motional mode of one of the ions in the chain.

Prototype of a phonon laser with trapped ions
Physical Review Research, 2023 We propose a tunable phonon laser prototype with a large trapped ion array, where some of the ions are effectively pinned by optical tweezers, thus isolating a subset of ions that mimics an acoustic cavity used as a phonon lasing resonator.

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

New Journal of PhysicsWe propose an experimental setup for manipulating the spontaneous emission (SE) of quantum scatterers, based on a spatial light modulator. We discuss this idea in the case of trapped barium ions as quantum emitters.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Trapped-Mg+ Apparatus for Control and Structure Studies [PDF]
, 2006 Trapped ions can be isolated from external perturbations such as collisions with other atoms or electric and magnetic field inhomogeneities. For this reason, trapped ions can be useful in spectral measurements, quantum information technology and ...
