Equilibrium phase transitions are associated with rearrangements of minima of a (Lagrangian) potential. Treatment of nonequilibrium systems requires doubling of degrees of freedom, which may be often interpreted as a transition from the "coordinate"- to the "phase"-space representation. As a result, one has to deal with the Hamiltonian formulation of the field theory instead of the Lagrangian one. We suggest a classification scheme of phase transitions in reaction-diffusion models based on the… 
Absorbing state phase transitions with a non-accessible vacuum
We analyse from the renormalization group perspective a universality class of reaction?diffusion systems with absorbing states. In this class, models where the vacuum state is not accessible are
On the absorbing-state phase transition in the one-dimensional triplet creation model
We study the lattice reaction diffusion model 3A -> 4A, A -> 0 (``triplet creation") using numerical simulations and n-site approximations. The simulation results provide evidence of a discontinuous
Persistence of instanton connections in chemical reactions with time-dependent rates.
This work studies the relation between the phase portrait of the Hamiltonian system representing a set of chemical reactions with constant rates and the corresponding system when these rates vary in time, and shows that the topology of the phase space is robust for small time-dependent perturbations.
Field theoretic treatment of an effective action for a model of catalyzed autoamplification.
This work shows how to systematically simplify the action for this model such that analytical expressions for the exponents of this universality class can be obtained by standard means and is expected to be of general applicability in reaction-diffusion systems with coupled order parameters that display qualitatively different behaviors close to criticality.
Critical behavior of a model for catalyzed autoamplification.
This model of catalyzed autoamplification inspired by a common motif in genetic networks has exponents that are distinct from previously studied reaction-diffusion systems, including the few with more than one field (unidirectionally coupled DP processes and the diffusive epidemic process).

The crossover behavior of various models exhibiting phase transition to absorbing phase with parity conserving class has been investigated by numerical simulations and cluster mean-field method and the resulting models show a diversity within the DP universality class in one dimension.

It is shown that the isotropic two-component AB --> [symbol: see text] model is insensitive to reaction disorder, and that only logarithmic corrections arise, induced by strong disorder in the diffusion rate.
Chemical Oscillations out of Chemical Noise
The large deviation theory is formally introduced, which allows developing a Hamiltonian dynamical system able to describe the system dynamics and shows that the intrinsic fluctuations, originated in the discrete character of the reagents, may sustain oscillations and chaotic trajectories which are impossible when these fluctuations are disregarded.
Emergence of fluctuating traveling front solutions in macroscopic theory of noisy invasion fronts.
Here, the theory is formulated as an effective Hamiltonian mechanics which operates with the density field and the conjugate "momentum" field and proves that the most probable density field history of an unusually slow front represents a traveling front solution of the Hamilton equations.
Universal Behaviors in the Diffusive Epidemic Process and in Fully Developed Turbulence
In this chapter, the phenomenology and challenges of the two systems studied as part of the thesis work are presented. Firstly, in Sect. 2.1 we give a short account on the physics of the diffusive


Critical behavior in reaction-diffusion systems exhibiting absorbing phase transitions
Phase transitions of reaction-diffusion systems with a site occupation restriction, particle creation requiring n > 2 parents, and in which explicit diffusion of single particles (A) is possible, are
On the nonequilibrium phase transition in reaction-diffusion systems with an absorbing stationary state
It is pointed out that chemical reactions which show an absorbing stationary state in the master-equation approach (e.g. Schlögl's first reaction) exhibit nevertheless a second order phase transition
Theory of Branching and Annihilating Random Walks.
A new universality class has been observed in d = 1 for even values of m, when the number of particles is locally conserved modulo 2, and another issue which clearly requires theoretical explanation is the occurrence of a transition at a finite value of σm.
Non-equilibrium critical phenomena and phase transitions into absorbing states
This review addresses recent developments in non-equilibrium statistical physics. Focusing on phase transitions from fluctuating phases into absorbing states, the universality class of directed

An example of a single-component, one-dimensional interacting particle system with a discontinuous transition into an absorbing state and the basic processes in the model are spontaneous annihilation, autocatalytic creation by trimers, and hopping.
Universality class of nonequilibrium phase transitions with infinitely many-absorbing-states
We consider systems whose steady states exhibit a nonequilibrium phase transition from an active state to one-among an infinite number-absorbing state, as some control parameter is varied across a
Pair contact process with diffusion: failure of master equation field theory.
It is concluded that a more coarse-grained effective field theory approach is required to elucidate the critical properties of the PCPD.
Critical properties of the reaction-diffusion model 2A-->3A, 2A-->0.
The steady-state phase diagram of the one-dimensional reaction-diffusion model 2A-->3A,2A-->0 is studied through the non-Hermitian density matrix renormalization group, where the value of beta/nu(perpendicular) is close to thevalue of the parity conserving universality class, in spite of the absence of local conservation laws.
Phase transition of a two-dimensional binary spreading model.
Large scale simulations of the particle density confirmed mean-field scaling behavior with logarithmic corrections, interpreted as numerical evidence supporting the bosonic field theoretical prediction that the upper critical dimension in this model is d(c)=2.
Phase transitions and correlations in the bosonic pair contact process with diffusion: exact results
The variance of the local density of the pair contact process with diffusion is investigated in a bosonic description. At the critical point of the absorbing phase transition (where the average
