Exponential error rates in multiple state discrimination on a quantum spin chain
Exponential error rates multiple state discrimination quantum spin chain
2015/8/25
We consider decision problems on finite sets of hypotheses represented by pairwise different shift-invariant states on a quantum spin chain. The decision in favor of one of the hypotheses is based on ...

FORMAL PSEUDODIFFERENTIAL OPERATORS AND WITTEN’S r-SPIN NUMBERS
FORMAL PSEUDODIFFERENTIAL OPERATORS WITTEN’S r-SPIN NUMBERS
2018/4/19
We derive an effective recursion for Witten’s r-spin intersection numbers, using Witten’s conjecture relating r-spin numbers to the Gel’fand-Dikii hierarchy (Theorem 4.1). Consequences include closed-...
On centralizer algebras for spin representations
centralizer algebras spin representations Quantum Algebra
2011/9/16
Abstract: We give a presentation of the centralizer algebras for tensor products of spinor representations of quantum groups via generators and relations. In the even-dimensional case, this can be des...
Baxter operators for arbitrary spin II

2011/10/10
Abstract: This paper presents the second part of our study devoted to the construction of Baxter operators for the homogeneous closed XXX spin chain with the quantum space carrying infinite or finite-...
Spheres with more than 7 vector fields: all the fault of Spin(9)
Spin(9) octonions vector fields on spheres
2011/8/24
Abstract: We give an interpretation in terms of the Lie group Spin(9) of the maximal number of linearly independent vector fields on odd dimensional spheres.
Diagonalization-free implementation of spin relaxation theory for large spin systems
NMR EPR relaxation simulation spin dynamics
2011/3/1
The Liouville space spin relaxation theory equations are reformulated in such a way as to avoid the computationally expensive Hamiltonian diagonalization step, replacing it by numerical evaluation of ...
New Examples of Compact Manifolds with Holonomy Spin(7)
New Examples of Compact Manifolds Holonomy Spin(7)
2011/2/21
We find new examples of compact Spin(7)-manifolds using a construction of Joyce [18, 19]. The essential ingredient in Joyce’s construction is a Calabi–Yau 4-orbifold with particular singularities admi...
4-dimensional Spin-foam Model with Quantum Lorentz Group
Quantum Group Loop Quantum Gravity Spin-foam Model
2011/3/3
We study the quantum group deformation of the Lorentzian EPRL spin-foam model. The construction
uses the harmonic analysis on the quantum Lorentz group. We show that the quantum group spin-foam model...
String hypothesis for gl(n|m) spin chains: a particle/hole democracy
String hypothesis gl(n|m) spin chains particle/hole democracy
2011/3/3
This paper is devoted to integrable gl(n|m) spin chains which allow for for-mulation of the string hypothesis. Considering the thermodynamic limit of such spin chains, we derive linear functional equa...
Asymptotic stability of spin orbit resonance for the dynamics of a viscoelastic satellite
Asymptotic stability spin orbit resonance dynamics viscoelastic satellite
2011/2/25
We prove the asymptotic stability of 1:1 spin orbit resonance for a stiff viscoelastic rotationally invariant satellite. The main point is that we do not assume any dissipation on the orbital degrees ...
Quantum deformation of two four-dimensional spin foam models
Quantum deformation two four-dimensional spin foam models
2011/3/3
We construct the q-deformed version of two four-dimensional spin foam models, the Eu-clidean and Lorentzian versions of the EPRL model. The q-deformed models are based on the representation theory of ...
Topological term in the non-linear $\sigma$ model of the SO(5) spin chains
Non-linear sigma model topological terms spin chains
2010/12/16
We show that there is a topological (Berry phase) term in the non-linear model description of the SO(5) spin chain. It distinguishes the linear and projective repre-sentations of the SO(5) symmetry ...
Quantum Singularity Theory for A_{r-1} and r-Spin Theory
Quantum Singularity Theory A_{r-1} and r-Spin Theory
2011/1/14
We give a review of the theories of [FJR] and the theory of [JKV]and prove that for the singularity Ar−1 = xr (with the group G = μr), the stack of Ar−1-curves of [FJR] is canonically isom...

2010/11/23
We present series study of using the method of super-symmetric quantum mechanics(SUSYQM) solving the spin-weighted spheroidal wave equation. In this paper, we obtain the first four terms of super-pot...
