The 10−3 eV frontier in neutrinoless double beta decay

open access: yesPhysics Letters B, 2018
The observation of neutrinoless double beta decay would allow to establish lepton number violation and the Majorana nature of neutrinos. The rate of this process in the case of 3-neutrino mixing is controlled by the neutrinoless double beta decay ...

Inference of neutrino nature and Majorana CP phases from $$\mathbf{0}{\nu \beta \beta }$$ 0 ν β β decays with inverted mass ordering

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Whether the neutrino mass ordering is normal or inverted remains an experimentally open issue in neutrino physics. The knowledge of neutrino mass ordering has great importance for neutrinoless double-beta ( $$ 0\nu \beta \beta $$ 0 ν β β ) decay ...

On Normal ordering and Canonical transformations in Thermal Field Theory [PDF]

open access: yes, 1997
We look at a real scalar field in thermal equilibrium in the context of the new normal ordering and field split defined by Evans and Steer. We show that the field split defines a natural canonical transformation, but that this transformation differs from

PARTIAL ORDER IN THE NORMAL CATEGORY ARISING FROM NORMAL BANDS [PDF]

open access: yesAdvances in Mathematics: Scientific Journal, 2020
The notion of normal category was introduced by KSS Nambooripad in connection with the study of the structure of regular semigroups using cross connections\cite{nambooripad1994theory}. It is an abstraction of the category of principal left ideals of a regular semigroup. A normal band is a semigroup $B$ satisfying $a^2=a$ and $abca=acba$ for all $a,b,c \

Stability of three neutrino flavor conversion in supernovae

open access: yes, 2019
Neutrino-neutrino interactions can lead to collective flavor conversion in the dense parts of a core collapse supernova. Growing instabilities that lead to collective conversions have been studied intensely in the limit of two-neutrino species and occur ...

Impaired serial ordering in nondemented patients with mild Parkinson's disease. [PDF]

open access: yesPLoS ONE, 2018
The ability to arrange thoughts and actions in an appropriate serial order (the problem of serial order) is essential to complex behaviors such as language, reasoning and cognitive planning.

Cosmology and the neutrino mass ordering

open access: yes, 2016
We propose a simple method to quantify a possible exclusion of the inverted neutrino mass ordering from cosmological bounds on the sum of the neutrino masses. The method is based on Bayesian inference and allows for a calculation of the posterior odds of

Neutrino Mass Ordering from Oscillations and Beyond: 2018 Status and Future Prospects

open access: yesFrontiers in Astronomy and Space Sciences, 2018
The ordering of the neutrino masses is a crucial input for a deep understanding of flavor physics, and its determination may provide the key to establish the relationship among the lepton masses and mixings and their analogous properties in the quark ...

Coherent state representation of squeezing operator and its applications

open access: yesResults in Physics, 2022
In a previous paper Zhan et al. (2022) proposed the coherent state representation for linear operator, which shows a beautiful theoretical value. Inspired by the work, we further extend it to the nonlinear case, including single- and two-mode squeezing ...

Combinatorics and Boson normal ordering: A gentle introduction

open access: yes, 2007
We discuss a general combinatorial framework for operator ordering problems by applying it to the normal ordering of the powers and exponential of the boson number operator.
