Surface defects and elliptic quantum groups

open access: yesJournal of High Energy Physics, 2017
A brane construction of an integrable lattice model is proposed. The model is composed of Belavin’s R-matrix, Felder’s dynamical R-matrix, the Bazhanov-Sergeev-Derkachov-Spiridonov R-operator and some intertwining operators.

Quantum Bernstein’s theorem and the hyperoctahedral quantum group [PDF]

open access: yesJournal of Mathematical Physics, 2018
We study an extension of Bernstein theorem to the setting of quantum groups. For a d-tuple of free identically distributed random variables, we consider a problem of preservation of freeness under the transformations from the free orthogonal quantum group.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Quantum Information in Geometric Quantum Mechanics [PDF]

open access: yes, 2011
A fundamental starting point in quantum information theory is the consideration of the von Neumann entropy and its generalization to relative quantum entropies.

T-Systems and Y-Systems for Quantum Affinizations of Quantum Kac-Moody Algebras

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
The T-systems and Y-systems are classes of algebraic relations originally associated with quantum affine algebras and Yangians. Recently the T-systems were generalized to quantum affinizations of a wide class of quantum Kac-Moody algebras by Hernandez ...

C*-Algebraic Quantum Groups Arising from Algebraic Quantum Groups [PDF]

open access: yesInternational Journal of Mathematics, 1997
We associate to an algebraic quantum group a C*-algebraic quantum group and show that this C*-algebraic quantum group essentially satisfies an upcoming definition of Masuda, Nakagami and Woronowicz.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Prime ideals in the quantum grassmanian [PDF]

open access: yes, 2008
We consider quantum Schubert cells in the quantum grassmannian and give a cell decomposition of the prime spectrum via the Schubert cells. As a consequence, we show that all primes are completely prime in the generic case where the deformation parameter ...

Towards the τ-function of the quantum groups

open access: yesPhysics Letters B
The theory of τ-functions is receiving attention, due to their appearance as non-perturbative partition functions of certain quantum field theories. These τ−functions satisfy Hirota’s bilinear identities (BI).

New R-matrices with non-additive spectral parameters and integrable models of strongly correlated fermions

open access: yesJournal of High Energy Physics, 2020
We present a general formula for constructing R-matrices with non-additive spectral parameters associated with a type-I quantum superalgebra. The spectral parameters originate from two one-parameter families of inequivalent finite-dimensional irreducible
