Neutrophilic polymorphonuclears (PMNs) play an important role in the progression of sepsis-related inflammation and become highly activated by a wide array of ligands on the site. The triggering...
Boundary effect of a partition in a quantum well (2006)
The paper wishes to demonstrate that, in quantum systems with boundaries, different boundary conditions can lead to remarkably different physical behaviour. Our seemingly innocent setting is a one...

Abstract Background Neutrophils represent the first line of defence against aggressions. The programmed death of neutrophils is delayed by pro-inflammatory stimuli to ensure a proper resolution of...
Cheon, Taksu, Tsutsui, Izumi, Fulop, Tamas
We show that the U(2) family of point interactions on a line can be utilized to provide the U(2) family of qubit operations for quantum information processing. Qubits are realized as localized states...
Physics of singular points in quantum mechanics (2003)
Defects or junctions in materials serve as a source of interactions for particles, and in idealized limits they may be treated as singular points yielding contact interactions. In quantum mechanics,...
Quantum force due to distinct boundary conditions (2003)
Fulop, Tamas, Miyazaki, Hitoshi, Tsutsui, Izumi
We calculate the quantum statistical force acting on a partition wall that divides a one dimensional box into two halves. The two half boxes contain the same (fixed) number of noninteracting bosons,...
Spectral properties on a circle with a singularity (2003)
Fulop, Tamas, Tsutsui, Izumi, Cheon, Taksu
We investigate the spectral and symmetry properties of a quantum particle moving on a circle with a pointlike singularity (or point interaction). We find that, within the U(2) family of the quantum...
On the inner structure of confined positronium (2003)
Fulop, Tamas, Farkas, Zeno, Seeger, Alfred, Major, Janos
We study the inner structure of a positronium confined to a void by treating it as a two-particle quantum system where the electron is captured by an infinite potential well and the positron feels...
Connection Conditions and the Spectral Family under Singular Potentials (2002)
Tsutsui, Izumi, Fulop, Tamas, Cheon, Taksu
To describe a quantum system whose potential is divergent at one point, one must provide proper connection conditions for the wave functions at the singularity. Generalizing the scheme used for point...
Classical Aspects of Quantum Walls in One Dimension (2001)
Fulop, Tamas, Cheon, Taksu, Tsutsui, Izumi
We investigate the system of a particle moving on a half line x >= 0 under the general walls at x = 0 that are permitted quantum mechanically. These quantum walls, characterized by a parameter L, are...
Spectral Structure of Quantum Line with a Defect (2001)
Cheon, Taksu, Fulop, Tamas, Tsutsui, Izumi
We study the spectral properties of one-dimensional quantum wire with a single defect. We reveal the existence of the non-trivial topological structures in the spectral space of the system, which are...
Moebius Structure of the Spectral Space of Schroedinger Operators with Point Interaction (2001)
Tsutsui, Izumi, Fulop, Tamas, Cheon, Taksu
The Schroedinger operator with point interaction in one dimension has a U(2) family of self-adjoint extensions. We study the spectrum of the operator and show that (i) the spectrum is uniquely...
Motivated by a novel method for granular segregation, we analyze the one dimensional drift-diffusion between two absorbing boundaries. The time evolution of the probability distribution and the rate...
Symmetry, Duality and Anholonomy of Point Interactions in One Dimension (2000)
Cheon, Taksu, Fulop, Tamas, Tsutsui, Izumi
We analyze the spectral structure of the one dimensional quantum mechanical system with point interaction, which is known to be parametrized by the group U(2). Based on the classification of the...
Duality and Anholonomy in Quantum Mechanics of 1D Contact Interactions (2000)
Tsutsui, Izumi, Fulop, Tamas, Cheon, Taksu
We study systems with parity invariant contact interactions in one dimension. The model analyzed is the simplest nontrivial one --- a quantum wire with a point defect --- and yet is shown to exhibit...
A Free Particle on a Circle with Point Interaction (1999)
The quantum dynamics of a free particle on a circle with point interaction is described by a U(2) family of self-adjoint Hamiltonians. We provide a classification of the family by introducing a...
Reduced SL(2,R) WZNW Quantum Mechanics (1995)
The $SL(2,\R)$ WZNW $\rightarrow$ Liouville reduction leads to a nontrivial phase space on the classical level both in $0+1$ and $1+1$ dimensions. To study the consequences in the quantum theory, the...
