The surface code with a twist [PDF]

open access: yesQuantum, 2017
The surface code is one of the most successful approaches to topological quantum error-correction. It boasts the smallest known syndrome extraction circuits and correspondingly largest thresholds.

A Stronger Theorem Against Macro-realism [PDF]

open access: yesQuantum, 2017
Macro-realism is the position that certain macroscopic observables must always possess definite values: e.g. the table is in some definite position, even if we do not know what that is precisely.

The Novel and Common Origin of Gamma-ray Bursts: A Galactic Seed Separation with Emitting Radiations

open access: yesReports in Advances of Physical Sciences, 2021
The mechanism of the gamma-ray burst is uncertain while the current candidates, respectively, for short and long GRBs are rather accepted. They conflict with some observed facts. Here we examine in detail the process for an energy circulation to separate

Quantum Horn's lemma, finite heat baths, and the third law of thermodynamics [PDF]

open access: yesQuantum, 2018
Interactions of quantum systems with their environment play a crucial role in resource-theoretic approaches to thermodynamics in the microscopic regime.

Numerical treatment with Lobatto IIIA technique for radiative flow of MHD hybrid nanofluid (Al2O3—Cu/H2O) over a convectively heated stretchable rotating disk with velocity slip effects

open access: yesAIP Advances, 2020
This study investigates the transportation of mass and heat in the 3D flow of hybrid nanofluids over a rotating disk in the presence of uniform magnetic field acting along the transverse direction to the flow.

First-passage, transition path, and looping times in conical varying-width channels: Comparison of analytical and numerical results

open access: yesAIP Advances, 2020
This paper deals with transitions of diffusing point particles between the two ends of expanding and narrowing two-dimensional conical channels. The particle trajectory starts from the reflecting boundary and ends as soon as the absorbing boundary is ...

Introduction to The Spiral Dynamics and The Spiral Coriolis Force [PDF]

open access: yes, 2018
The spiral dynamics of a point-like body of mass m in spiral differential geometry are introduced. New ideal motions have been studied, the uniform spiral motion and the uniform spiral-polar motion.

κ-deformed covariant quantum phase spaces as Hopf algebroids

open access: yesPhysics Letters B, 2015
We consider the general D=4 (10+10)-dimensional κ-deformed quantum phase space as given by Heisenberg double H of D=4 κ-deformed Poincaré–Hopf algebra H.

On elementary proof of AGT relations from six dimensions

open access: yesPhysics Letters B, 2016
The actual definition of the Nekrasov functions participating in the AGT relations implies a peculiar choice of contours in the LMNS and Dotsenko–Fateev integrals.
