Mobile impurity in a two-leg bosonic ladder

Physical Review Research
We study the dynamics of a mobile impurity in a two-leg bosonic ladder. The impurity moves both along and across the legs and interacts with a bath of interacting bosonic particles present in the ladder. We use both analytical (Tomonaga-Luttinger liquid)

On the distance eigenvalues of Cayley graphs

پژوهش‌های ریاضی, 2022
In this paper, graphs are undirected and loop-free and groups are finite. By Cn, Kn and Km,n we mean the cycle graph with n vertices, the complete graph with n vertices and the complete bipartite graph with parts size m and n, respectively.

Long-range interacting many-body systems in the irrep basis

Physical Review Research
Spin models featuring infinite-range, homogeneous all-to-all interactions can be efficiently described due to the existence of a symmetry-restricted Hilbert subspace and an underlying classical phase-space structure.

Crystal structures of four gold(I) complexes [AuL2]+[AuX2]− and a by-product (L·LH+)[AuBr2]− (L = substituted pyridine, X = Cl or Br)

Acta Crystallographica Section E: Crystallographic Communications
Bis(2-methylpyridine)gold(I) dibromidoaurate(I), [Au(C6H7N)2][AuBr2], (1), crystallizes in space group C2/c with Z = 4. Both gold atoms lie on twofold axes and are connected by an aurophilic contact.

Parity features for classes of the infinite symmetric group

Journal of Combinatorial Theory, Series A, 1982
AbstractA conjugacy class in the infinite-symmetric group is said to have parity features if no finitary odd permutation is a product of two of its members. The conjugacy classes having parity features are determined. The role played by a property of this kind in determining products of conjugacy classes in any group in which every element is conjugate

The homomorphic images of infinite symmetric groups

Forum Mathematicum, 1993
Let \(\kappa\) be an infinite cardinal and \(S(\kappa)\) the infinite symmetric group of all permutations of a set of cardinality \(\kappa\). If \(\omega \leq \lambda \leq \kappa\), let \(S_ \lambda(\kappa)\) be the normal subgroup of \(S(\kappa)\) comprising all permutations which move fewer then \(\lambda\) symbols.
