Coherent state of the harmonic oscillator [PDF]
, 2021 In classical physics, for a harmonic oscillator with a certain energy, position and momentum oscillate in time sinusoidally. However, in a Quantum harmonic oscillator, the expectation of position and momentum operators at a given energy level (En) are ...

SU(2) symmetry of coherent photons and application to Poincaré rotator
Frontiers in Physics, 2023 Lie algebra is a hidden mathematical structure behind various quantum systems realised in nature. Here, we consider SU(2) wavefunctions for polarisation states of coherent photons emitted from a laser source, and discuss the relationship to spin ...

Heterogeneity in M. tuberculosis β-lactamase inhibition by Sulbactam
Nature Communications, 2023 For decades, researchers have elucidated essential enzymatic functions on the atomic length scale by tracing atomic positions in real-time. Our work builds on possibilities unleashed by mix-and-inject serial crystallography (MISC) at X-ray free electron ...

Spin and orbital angular momentum of coherent photons in a waveguide
Frontiers in Physics, 2023 Spin angular momentum of a photon corresponds to a polarisation degree of freedom of lights, and such that various polarisation properties are coming from macroscopic manifestation of quantum-mechanical properties of lights.

DIFFUSION PROCESSES AND COHERENT STATES [PDF]
Modern Physics Letters B, 1994 It is shown that uncertanity relations, as well as coherent and squeezed states, are structural properties of stochastic processes with Fokker–Planck dynamics. The quantum mechanical coherent and squeezed states are explicitly constructed via Nelson stochastic quantization.

Self-organized complexity and Coherent Infomax from the viewpoint of Jaynes’s probability theory [PDF]
, 2012 This paper discusses concepts of self-organized complexity and the theory of Coherent Infomax in the light of Jaynes’s probability theory. Coherent Infomax, shows, in principle, how adaptively self-organized complexity can be preserved and improved by ...

Coherent states and duality [PDF]
Physics Letters A, 2002 We formulate a relation between quantum-mechanical coherent states and complex-differentiable structures on the classical phase space ${\cal C}$ of a finite number of degrees of freedom. Locally-defined coherent states parametrised by the points of ${\cal C}$ exist when there is an almost complex structure on ${\cal C}$.

Calculation of the multimode Franck-Condon factors based on the coherent state method [PDF]
, 2005 The equivalence of two ways for the calculation of overlap integrals, i.e. the Sharp Rosenstock generating function method and the Doktorov coherent state method, has been proved.
