On the First Passage Time and Leapover Properties of Levy Motions
T. Koren, A. V. Chechkin, J. Klafter
We investigate two coupled properties of Levy stable random motions: The first passage times (FPTs) and the first passage leapovers (FPLs). While, in general, the FPT problem has b…
Formation of molecules and entangled atomic pairs from atomic BEC due to Feshbach resonance
Vladimir A. Yurovsky
Bose-Einstein condensate (BEC) is considered under conditions of Feshbach resonance in two-atom collisions due to a coupling of atomic pair and resonant molecular states. The assoc…
Soft quasicrystals - Why are they stable?
Ron Lifshitz, Haim Diamant
In the last two years we have witnessed the exciting experimental discovery of soft matter with nontrivial quasiperiodic long-range order - a new form of matter termed a soft quasi…
Miscibility in a degenerate fermionic mixture induced by linear coupling
Sadhan K. Adhikari, Boris A. Malomed
We consider a one-dimensional mean-field-hydrodynamic model of a two-component degenerate Fermi gas in an external trap, each component representing a spin state of the same atom.…
Long-range hydrodynamic response of particulate liquids and liquid-laden solids
Haim Diamant
In viscous particulate liquids, such as suspensions and polymer solutions, the large-distance steady-state flow due to a local disturbance is commonly described in terms of hydrody…
An effective potential for one-dimensional matter-wave solitons in an axially inhomogeneous trap
Sergio De Nicola, Boris A. Malomed, Renato Fedele
We demonstrate that a tight transverse trap with the local frequency, , gradually varying in the longitudinal direction () induces an effective potential for one-di…
