An operatorial model for long-term survival of bacterial populations
This paper deals with the application of the operatorial techniques of quantum physics to model a closed ecosystem in a two-dimensional region. In particular, we consider a model with four
On fermionic models of a closed ecosystem with application to bacterial populations
This paper deals with the application of operatorial techniques of quantum physics to a theoretical model of closed ecosystems. The model is built by using fermionic operators whose evolution is
Dynamics of Confined Crowd Modelled Using Fermionic Operators
An operatorial method based on fermionic operators is used to describe the dynamics of a crowd made of different kind of populations mutually interacting and moving in a two–dimensional bounded

Non-Hermitian Operator Modelling of Basic Cancer Cell Dynamics
The approach is quantum-like: ladder and number operators are used to describe healthy and tumor cells birth and death, and the evolution is ruled by a non-hermitian Hamiltonian which includes, in a non reversible way, the basic biological mechanisms for the system.


A phenomenological operator description of interactions between populations with applications to migration
We adopt an operatorial method based on the so-called creation, annihilation and number operators in the description of different systems in which two populations interact and move in a
Damping and pseudo-fermions
After a short abstract introduction on the time evolution driven by non-self-adjoint Hamiltonians, we show how the recently introduced concept of pseudo-fermion can be used in the description of
An Operator-Like Description of Love Affairs
The so-called occupation number representation is adopted, originally used in quantum mechanics and recently considered in the description of stock markets, in the analysis of the dynamics of love relations, and analytical conditions for the linear model of the love triangle to have periodic or quasi-periodic solutions are found.
The Dynamical Problem for a Non Self-adjoint Hamiltonian
After a compact overview of the standard mathematical presentations of the formalism of quantum mechanics using the language of C*- algebras and/or the language of Hilbert spaces we turn attention to
Quantum and Ecosystem Entropies
A phase space entropy model of ecosystems is developed and a discussion of some broader aspects of an ecosystem phase space is discussed, including the principle of maximum entropy at equilibria.
Classical limit of non-Hermitian quantum dynamics—a generalized canonical structure
We investigate the classical limit of non-Hermitian quantum dynamics arising from a coherent state approximation, and show that the resulting classical phase space dynamics can be described by
Quantum physics meets biology
The criteria for a future “quantum biology,” its current status, recent experimental progress, and also the restrictions that nature imposes on bold extrapolations of quantum theory to macroscopic phenomena are discussed.
