Directed polymers on a Cayley tree with spatially correlated disorder
Yadin Y. Goldschmidt
In this paper we consider directed walks on a tree with a fixed branching ratio K at a finite temperature T. We consider the case where each site (or link) is assigned a random ene…
Novel non-equilibrium critical behavior in unidirectionally coupled stochastic processes
Y. Y. Goldschmidt, H. Hinrichsen, M. Howard +1
Phase transitions from an active into an absorbing, inactive state are generically described by the critical exponents of directed percolation (DP), with upper critical dimension d…
Phase Transitions of the Flux Line Lattice in High-Temperature Superconductors with Weak Columnar and Point Disorder
Yadin Y. Goldschmidt
We study the effects of weak point and columnar disorder on the vortex-lattice phase transitions in high temperature superconductors. The combined effect of thermal fluctuations an…

We study the effects of weak columnar and point disorder on the vortex-lattice phase transitions in high temperature superconductors. The combined effect of thermal fluctuations an…
Quantum fluctuations and glassy behavior: The case of a quantum particle in a random potential
Yadin Y. Goldschmidt
In this paper we expand our previous investigation of a quantum particle subject to the action of a random potential plus a fixed harmonic potential at a finite temperature T. In t…
Manifolds in random media: A variational approach to the spatial probability distribution
Yadin Y. Goldschmidt
We develop a new variational scheme to approximate the position dependent spatial probability distribution of a zero dimensional manifold in a random medium. This celebrated 'toy-m…
Manifolds in random media: Beyond the variational approximation
Yadin Y. Goldschmidt
In this paper we give a closed form expression for the corrections to the self-energy characterizing the correction function of a manifold in random media. This amounts to th…
