Self-localization of directed polymers and oppressive population control
T. J. Newman, Eugene B. Kolomeisky
We construct a phenomenological theory of self-localization of directed polymers in d+1 dimensions. In d=1 we show that the polymer is always self-localized, whereas in d=2 there i…

Manifold self-localization in a deformable medium
Eugene B. Kolomeisky, Joseph P. Straley
Directed manifolds (domain walls, interfaces, vortex lines) in a deformable medium can exist in a correlated state in which the manifold is self-localized by its own strain field.…

Statics and dynamics of a one-dimensional quantum many-body system
Eugene B. Kolomeisky, Joseph P. Straley
The macroscopic zero-temperature behavior of weakly- incommensurate systems in one dimension is described in terms of solitons. The soliton density n obeys equations displaying sev…
