Interplay of finite-energy and finite-momentum superconducting pairing [PDF]
Phys. Rev. B 106, 024511 (2022), 2022 Understanding the nature of Cooper pairs is essential to describe the properties of superconductors. The original proposal of Bardeen, Cooper, and Schrieffer (BCS) was based on electrons pairing with same energy and zero center-of-mass momentum. With the advent of new superconductors, different forms of pairing have been discussed.

Pairing for Greenhorn: Survey and Future Perspective [PDF]
arXiv, 2021 Pairing is the most powerful tool in cryptography that maps two points on the elliptic curve to the group over the finite field. Mostly cryptographers consider pairing as a black box and use it for implementing pairing-based cryptographic protocols. This paper aims to give the overview of pairing as simple as possible for greenhorn and those who are ...

A Class of Exactly Solvable Pairing Models [PDF]
Phys.Rev.Lett. 87 (2001) 066403, 2001 We present three classes of exactly solvable models for fermion and boson systems, based on the pairing interaction. These models are solvable in any dimension. As an example we show the first results for fermion interacting with repulsive pairing forces in a two dimensional square lattice.

Amplification of Cooper pair splitting current in a graphene based Cooper pair beam splitter geometry [PDF]
Phys. Rev. B 96, 125406 (2017), 2017 Motivated by the recent experiments [Scientific reports 6, 23051 (2016), Phys. Rev. Lett. 114, 096602 (2015)], we theoretically investigate Cooper pair splitting current in a graphene based Cooper pair beam splitter geometry. By considering the graphene based superconductor as an entangler device, instead of normal (2D) BCS superconductor, we show that

Isovector and isoscalar proton-neutron pairing in $N>Z$ nuclei [PDF]
Phys. Rev. C 98, 064319 (2018), 2018 We propose a particle number conserving formalism for the treatment of isovector-isoscalar pairing in nuclei with $N>Z$. The ground state of the pairing Hamiltonian is described by a quartet condensate to which is appended a pair condensate formed by the neutrons in excess. The quartets are built by two isovector pairs coupled to the total isospin $T=0$

Dipole-Coupled Defect Pairs as Deterministic Entangled Photon Pair Sources [PDF]
Phys. Rev. Research 2, 043328 (2020), 2020 Scalable quantum systems require deterministic entangled photon pair sources. Here, we demonstrate a scheme that uses a dipole-coupled defect pair to deterministically emit polarization-entangled photon pairs. Based on this scheme, we predict spectroscopic signatures and quantify the entanglement with physically realizable system parameters.

Two classes of reducible cyclic codes with large minimum symbol-pair distances [PDF]
arXiv, 2023 The high-density data storage technology aims to design high-capacity storage at a relatively low cost. In order to achieve this goal, symbol-pair codes were proposed by Cassuto and Blaum \cite{CB10,CB11} to handle channels that output pairs of overlapping symbols.

Probing the pairing symmetry in kagome superconductors based on the single-particle spectrum [PDF]
Phys. Rev. B 109, 054504 (2024)We investigate the single-particle spectra of recently discovered kagome superconductors. We examine nine distinct superconducting pairing symmetries, including the uniform $s$-wave pairing function, nearest-neighbor and next-nearest-neighbor $s$-wave pairing, $p+ip$ pairing, $d+id$ pairing, and $f$-wave pairing states.

SentPWNet: A Unified Sentence Pair Weighting Network for Task-specific Sentence Embedding [PDF]
arXiv, 2020 Pair-based metric learning has been widely adopted to learn sentence embedding in many NLP tasks such as semantic text similarity due to its efficiency in computation. Most existing works employed a sequence encoder model and utilized limited sentence pairs with a pair-based loss to learn discriminating sentence representation.

Modulations of the local pairing interaction near magnetic impurities in d-wave superconductors [PDF]
J. Supercond. Novel Magn. 26, 1729 (2013), 2012 The spin-fluctuation based pairing mechanism has proven successful in explaining the pairing symmetries due to Fermi surface nesting of both cuprates and iron-based materials. In this work, we study signatures of a spin-fluctuation mediated pairing at the local scale.
