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.…
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…
Gap solitons in quasiperiodic optical lattices
Hidetsugu Sakaguchi, Boris A. Malomed
Families of solitons in one- and two-dimensional (1D and 2D) Gross-Pitaevskii equations with the repulsive nonlinearity and a potential of the quasicrystallic type are constructed…
X,Y,Z-Waves: Extended Structures in Nonlinear Lattices
P. G. Kevrekidis, J. Gagnon, D. J. Frantzeskakis +1
Motivated by recent experimental and theoretical results on optical X-waves, we propose a new type of waveforms in 2D and 3D discrete media -- multi-legged extended nonlinear struc…
Two-dimensional loosely and tightly bound solitons in optical lattices and inverted traps
H. Sakaguchi, B. A. Malomed
We study the dynamics of nonlinear localized excitations (solitons) in two-dimensional (2D) Bose-Einstein condensates (BECs) with repulsive interactions, loaded into an optical lat…
Modulational Instability in Bose-Einstein Condensates under Feshbach Resonance Management
Z. Rapti, G. Theocharis, P. G. Kevrekidis +1
We investigate the modulational instability of nonlinear Schr{ö}dinger equations with periodic variation of their coefficients. In particular, we focus on the case of the recently…
