  text: We prove absence of ground states in the infrared-divergent spin boson model
    at large coupling. Our key argument reduces the proof to verifying long range
    order in the dual one-dimensional continuum Ising model, i.e., to showing that
    the respective two point function is lower bounded by a strictly positive constant.
    We can then use known results from percolation theory to establish long range
    order at large coupling. Combined with the known existence of ground states at
    small coupling, our result proves that the spin boson model undergoes a phase
    transition with respect to the coupling strength. We also present an expansion
    for the vacuum overlap of the spin boson ground state in terms of the Ising $n$-point
    functions, which implies that the phase transition is unique, i.e., that there
    is a critical coupling constant below which a ground state exists and above which
    none can exist.

  text: We study the ultraviolet problem for models of a finite-dimensional quantum
    mechanical system linearly coupled to a bosonic quantum field, such as the (many-)spin
    boson model or its rotating-wave approximation. If the state change of the system
    upon emission or absorption of a boson is either given by a normal matrix or by
    a 2-nilpotent one, which is the case for the previously named examples, we prove
    an optimal renormalization result. We complement it, by proving the norm resolvent
    convergence of appropriately regularized models to the renormalized one. Our method
    consists of a dressing transformation argument in the normal case and an appropriate
    interior boundary condition for the 2-nilpotent case.

  text: In this short communication we discuss the ultraviolet renormalization of
    the van Hove-Miyatake scalar field, generated by any distributional source. An
    abstract algebraic approach, based on the study of a special class of ground states
    of the van Hove-Miyatake dynamical map is compared with an Hamiltonian renormalization
    that makes use of a non-unitary dressing transformation. The two approaches are
    proved to yield equivalent results.

  text: In this paper we construct the non-trivial, renormalized Hamiltonian for a
    class of spin-boson models with supercritical form factors, including the one
    describing the Weisskopf-Wigner spontaneous emission. The renormalization is performed
    through both a self-energy and mass renormalization, in the so-called Hamiltonian
    formalism of constructive quantum field theory, implemented by a non-unitary dressing
    transformation. This solves the problem of triviality for unitarily-renormalized
    supercritical spin-boson models.

  text: We study the convergence rate of translation-invariant discrete-time quantum
    dynamics on a one-dimensional lattice. We prove that the cumulative distributions
    function of the ballistically scaled position $\mathbb X(n)/{n}$ after $n$ steps
    converges at a rate of $n^{-1/3}$ in the Lévy metric as $n\to\infty$. In the special
    case of step-coin quantum walks with two-dimensional coin space, we recover the
    same convergence rate for the supremum distance and prove optimality.

  text: We propose a definition of Coxeter-Dynkin algebras of canonical type generalising
    the definition as a path algebra of a quiver. Moreover, we construct two tilting
    objects over the squid algebra - one via generalised APR-tilting and one via one-point-extensions
    and reflection functors - and identify their endomorphism algebras with the Coxeter-Dynkin
    algebra. This shows that our definition gives another representative in the derived
    equivalence class of the squid algebra, and hence of the corresponding canonical
    algebra. Finally, we have a closer look at the Grothendieck group and the Euler
    form which illustrates the connection to Saito's classification of marked extended
    affine root systems. On the other hand, this enables us to prove that in the domestic
    case Coxeter-Dynkin algebras are of finite representation type.

  text: We construct good GKP (Gottesman-Kitaev-Preskill) codes (in the sense of Conrad,
    Eisert and Seifert proposed) from standard short integer solution lattices (SIS)
    as well as from ring SIS and module SIS lattices, R-SIS and M-SIS lattices, respectively.
    These lattice are crucial for lattice-based cryptography. Our construction yields
    GKP codes with distance $\sqrt{n/πe}$. This compares favorably with the NTRU-based
    construction by Conrad et al. that achieves distance $Ω(\sqrt{n/q}),$ with $n\le
    q^2/0.28$. Unlike their codes, our codes do not have secret keys that can be used
    to speed-up the decoding. However, we present a simple decoding algorithm that,
    for many parameter choices, experimentally yields decoding results similar to
    the ones for NTRU-based codes. Using the R-SIS and M-SIS construction, our simple
    decoding algorithm runs in nearly linear time. Following Conrad, Eisert and Seifert's
    work, our construction of GKP codes follows directly from an explicit, randomized
    construction of symplectic lattices with (up to constants $\approx 1$) minimal
    distance $(1/σ_{2n})^{1/2n}\approx \sqrt{\frac{n}{πe}}$, where $σ_{2n}$ is the
    volume of the 2n-dimensional unit ball. Before this result, Buser and Sarnak gave
    a non-constructive proof for the existence of such symplectic lattices.
