On (Schr\"oedinger's) quest for new physics for life (2009)
Two recent investigations are reviewed: quantum effects for DNA aggregates and scars formation on virus capsids. The possibility that scars could explain certain data recently obtained by Sundquist's...
Effects of Quantum Vacuum Fluctuations of the Electric Field on DNA Condensation (2009)
Iorio, Alfredo, Sen, Samik, Sen, Siddhartha
By assuming that not only counter-ions but DNA molecules as well are thermally distributed according to a Boltzmann law, we propose a modified Poisson-Boltzmann equation at the classical level as...
Scar-Driven Shape-Changes of Virus Capsids (2008)
Iorio, Alfredo, Sen, Siddhartha
We propose that certain patterns (scars) -- theoretically and numerically predicted to be formed by electrons arranged on a sphere to minimize the repulsive Coulomb potential (the Thomson problem)...
Do quantum effects hold together DNA condensates? (2008)
Iorio, Alfredo, Sen, Samik, Sen, Siddhartha
The classical electrostatic interaction between DNA molecules in water in the presence of counterions is reconsidered and we propose it is governed by a modified Poisson-Boltzmann equation. Quantum...
Virus Structure: From Crick and Watson to a New Conjecture (2007)
Iorio, Alfredo, Sen, Siddhartha
We conjecture that certain patterns (scars), theoretically and numerically predicted to be formed by electrons arranged on a sphere to minimize the repulsive Coulomb potential (the Thomson problem)...
Three Questions on Lorentz Violation (2006)
We review the basics of the two most widely used approaches to Lorentz violation - the Stardard Model Extension and Noncommutative Field Theory - and discuss in some detail the example of the...
Topological Constraints on the Charge Distributions for the Thomson Problem (2006)
Iorio, Alfredo, Sen, Siddhartha
The method of Morse theory is used to analyze the distributions of unit charges interacting through a repulsive force and constrained to move on the surface of a sphere -- the Thomson problem. We...
Castorina, Paolo, Iorio, Alfredo, Zappala', Dario
We show that in the framework of noncommutative classical electrodynamics Cherenkov radiation is permitted in vacuum and we explicitly compute its spectrum at first order in the noncommutative...
Topological Gravity, Kaluza-Klein Reduction, and the Kink (2004)
Kaluza-Klein reduction of the 3-dimensional gravitational Chern-Simons term leads to a 2-dimensional theory that supports a symmetry breaking solution and an associated kink interpolating between AdS...
Semiclassical Shor's Algorithm (2003)
Giorda, Paolo, Iorio, Alfredo, Sen, Samik, Sen, Siddhartha
We propose a semiclassical version of Shor's quantum algorithm to factorize integer numbers, based on spin-1/2 SU(2) generalized coherent states. Surprisingly, we find evidences that the algorithm's...
Quantization of Scalar Fields in Curved Background and Quantum Algebras (2001)
Iorio, Alfredo, Lambiase, Gaetano, Vitiello, Giuseppe
We show that a suitable deformation of the algebra $h_k(1)$ of the creation and annihilation operators for a complex scalar field, initially quantized in Minkowski space--time, induces the canonical...
Quantum Groups and Von Neumann Theorem (2000)
Iorio, Alfredo, Vitiello, Giuseppe
We discuss the $q$ deformation of Weyl-Heisenberg algebra in connection with the von Neumann theorem in Quantum Mechanics. We show that the $q$-deformation parameter labels the Weyl systems in...
Quantization of Damped Harmonic Oscillator, Thermal Field Theories and q-Groups (2000)
Iorio, Alfredo, Vitiello, Giuseppe
We study the canonical quantization of the damped harmonic oscillator by resorting to the realization of the q-deformation of the Weyl-Heisenberg algebra (q-WH) in terms of finite difference...
Supersymmetric Noether Currents and Seiberg-Witten Theory (2000)
A reliable method to construct Supersymmetric Noether currents is presented. As the most important application the central charge of the N=2 Supersymmetric Yang-Mills effective theory, known as...
A note on Seiberg-Witten central charge (1999)
The central charge for the Seiberg-Witten low-energy effective Action is computed using Noether supercharges. A reliable method to construct supersymmetric Noether currents is presented.
QUANTUM DISSIPATION AND QUANTUM GROUPS (1995)
Iorio, Alfredo, Vitiello, Giuseppe
We discuss the r\^ole of quantum deformation of Weyl-Heisenberg algebra in dissipative systems and finite temperature systems. We express the time evolution generator of the damped harmonic...
