Density-matrix-formalism based scheme for polarization mode dispersion monitoring and compensation in optical fiber communication systems
We propose a density-matrix-formalism based scheme to study polarization mode dispersion (PMD) monitoring and compensation in optical fiber...

Density Operator Formalism
The occupation probabilities of energy levels of a macroscopic system in thermodynamic equilibrium are independent of time. The formalism of...

The in-out formalism for in-in correlators
Cosmological correlators, the natural observables of the primordial universe, have been extensively studied in the past two decades using the in-in...

Matrix formalism used to describe the inertial properties in multibody dynamics
A matrix-based representation of the inertial characteristics with possible used in multibody dynamics is presented in the paper. The paper aims to...

Unitarity and the LSZ Formalism
In this chapter, we discuss how the LSZ formalism naturally incorporates unitarityUnitarity, a central physical requirement for the S-matrix, as also...

Fermi gas formalism for D-type quiver Chern-Simons theory with non-uniform ranks
We construct the Fermi gas formalism for the partition function of supersymmetric Chern-Simons theories with affine D -type quiver diagrams with...
-
The ambient space formalism
We present a new formalism to solve the kinematical constraints due to Weyl invariance for CFTs in curved backgrounds and/or non-trivial states, and...

Global conformal blocks via shadow formalism
We study 𝔰𝔩 2 and 𝔰𝔩 3 global conformal blocks on a sphere and a torus, using the shadow formalism. These blocks arise in the context of Virasoro...

The Lehmann Symanzik Zimmermann (LSZ) Formalism
In this chapter, we give an exhaustive account of the Lehmann-Symanzik-Zimmermann (LSZ) formalism which forms the very bedrock of the...

One loop mass renormalization of massive states using pure spinor formalism
As a check of the first massive integrated vertex operator in the pure spinor formalism constructed in ar**v:1802.04486 , we compute the one loop...

Torus shadow formalism and exact global conformal blocks
Using the shadow formalism we find global conformal blocks of torus CFT 2 . It is shown that n -point torus blocks in the “necklace” channel (a loop...

Worldsheet formalism for decoupling limits in string theory
We study the bosonic sector of a decoupling limit of type IIA superstring theory, where a background Ramond-Ramond one-form is fined tuned to its...

The shadow formalism of Galilean CFT2
In this work, we develop the shadow formalism for two-dimensional Galilean conformal field theory (GCFT 2 ). We define the principal series...

Three-particle Lellouch-Lüscher formalism in moving frames
A manifestly relativistic-invariant Lellouch-Lüscher formalism for the decays into three identical particles with no two-to-three transitions is...

Singular Lagrangians and the Faddeev-Jackiw Formalism in Classical Mechanics
Classical mechanical systems with internal constraints will be examined using the extended symplectic formalism of Faddeev-Jackiw. We will derive the...

Post-inflationary leptogenesis and dark matter production: metric versus Palatini formalism
We investigate production of non-thermal dark matter particles and heavy sterile neutrinos from inflaton during the reheating era, which is preceded...

Compton scattering in TFD formalism
In this paper, the cross section for the Compton scattering process at finite temperature is calculated. Temperature effects are introduced using the...

Nearly critical superfluids in Keldysh-Schwinger formalism
We examine the effective theory of critical dynamics near superfluid phase transitions in the framework of the Keldysh-Schwinger formalism. We focus...

A note on the stabilizer formalism via noncommutative graphs
In this short note, we formulate a stabilizer formalism in the language of noncommutative graphs. The classes of noncommutative graphs we consider...

The Evolution Formalism
The general covariant approach to General Relativity is not adapted to our experience from everyday life. The most intuitive concept is not that of...
