2. Wave packet - Wikipedia

   en.wikipedia.org/wiki/Wave_packet

   For example, if an electron wave packet is initially localized in a region of atomic dimensions (i.e., 10 −10 m) then the width of the packet doubles in about 10 −16 s. Clearly, particle wave packets spread out very rapidly indeed (in free space): [ 17 ] For instance, after 1 ms, the width will have grown to about a kilometer.

3. SIESTA (computer program) - Wikipedia

   en.wikipedia.org/wiki/SIESTA_(computer_program)

   Projects the electron wave functions and density onto a real-space grid to calculate the Hartree and exchange-correlation potentials and their matrix elements. Besides the standard Rayleigh-Ritz eigenstate method , it allows the use of localized linear combinations of the occupied orbitals (valence-bond or Wannier-like functions), making the ...

   Multi-configuration time-dependent Hartree (MCTDH) is a general algorithm to solve the time-dependent Schrödinger equation for multidimensional dynamical systems consisting of distinguishable particles.

9. Trojan wave packet - Wikipedia

   en.wikipedia.org/wiki/Trojan_wave_packet

   In physics, a wave packet is a short "burst" or "envelope" of wave action that travels as a unit. A wave packet can be analyzed into, or can be synthesized from, an infinite set of component sinusoidal waves of different wavenumbers, with phases and amplitudes such that they interfere constructively only over a small region of space, and destructively elsewhere.
