We investigate the propagation of a spatial soliton in an optical lattice imprinted in a nonlocal thermal media with infinite range of nonlocality. A variational approach is used to obtain dynamical equation for beam width, amplitude and curvature. Furthermore an approximate formula to form a quasi-soliton is obtained. What implying that Gaussian function is a good approximation to a nonlocal spatial soliton in such thermal media with lattices when the lattice period is larger. Numerical simulations show the dynamic propagation of the quasi-solitons..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
