Lattice models from CFT on surfaces with holes II: Cloaking boundary conditions and loop models
In this paper we continue to investigate the lattice models obtained from 2d CFTs via the construction introduced in [arXiv:2112.01563]. On the side of the 2d CFT we consider the cloaking boundary…

Coherent States of Graphene Layer with and without a PT-symmetric Chemical Potential
In this paper we construct different classes of coherent and bicoherent states for the graphene tight-binding model in presence of a magnetic field, and for a deformed version where we include a…

Mittag-Leffler Probability Density for Nonextensive Statistics and Superstatistics
It is shown that a Mittag-Leffler density has interesting properties. The Mittag-Leffler random variable has a structural representation in terms of a positive Levy variable and the power of a gamma…

Interrelations between dualities in classical integrable systems and classical-classical version of quantum-classical duality
We describe the Ruijsenaars' action-angle duality in classical many-body integrable systems through the spectral duality transformation relating the classical spin chains and Gaudin models. For this…

Large deviations for the log-Gamma polymer
We conjecture an explicit expression for the lower tail large deviation rate function of the partition function of the log-Gamma polymer. We rigorously prove our result, except for one step for which…

Continuum limit of resonances for discrete Schr\"odinger operators
We consider complex resonances for discrete and continuous Schr\"odinger operators, and we show that the resonances of discrete models converge to resonances of continuous models in the continuum…

Cosmological Landsberg Finsler spacetimes
We locally classify all possible cosmological homogeneous and isotropic Landsberg-type Finsler structures, in 4-dimensions. Among them, we identify viable non-stationary Finsler spacetimes, i.e.…

Spectral regularity and defects for the Kohmoto model
We study the Kohmoto model including Sturmian Hamiltonians and the associated Kohmoto butterfly. We prove spectral estimates for the operators using Farey numbers. In addition, we determine the…

On the properties of coframes
We consider injectivity and surjectivity of some maps on the exterior algebra of isomorphic finite-dimensional vector spaces. We prove the properties of the maps in full generality, for any dimension…

Truncated Floquet-Bloch transform for computing the spectral properties of large finite systems of resonators
The truncated Floquet-Bloch transform can be used to characterise the spectral properties of finite periodic and aperiodic large systems of resonators. This paper aims to provide for the first time…

Arctic curves of periodic dimer models and generalized discriminants
We compute the algebraic equation for arctic curves of the Aztec diamond with a doubly (quasi-)periodic weight structure and obtain similar results for certain models of the hexagon. In particular,…

Spectral analysis of infinite Marchenko-Slavin matrices
This work tackles the problem of spectral characterization of a class of infinite matrices arising from the modelling of small oscillations in a system of interacting particles. The class of matrices…

The second order Huang-Yang formula to the 3D Fermi gas: the Gross-Pitaevskii regime
For a system of N Fermions of spin 1/2, with its interaction potential of scattering length a, the classical Huang-Yang formula states that the energy density e() is of the form…
