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.","lang":"eng"}],"project":[{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"}],"_id":"63642","language":[{"iso":"eng"}],"user_id":"99427","status":"public","title":"On the Ising Phase Transition in the Infrared-Divergent Spin Boson Model","year":"2025","author":[{"first_name":"Volker","last_name":"Betz","full_name":"Betz, Volker"},{"orcid":"0000-0001-9074-1205","first_name":"Benjamin","last_name":"Hinrichs","full_name":"Hinrichs, Benjamin","id":"99427"},{"full_name":"Kraft, Mino Nicola","last_name":"Kraft","first_name":"Mino Nicola"},{"first_name":"Steffen","last_name":"Polzer","full_name":"Polzer, Steffen"}],"date_updated":"2026-01-16T08:57:21Z"},{"user_id":"99427","_id":"63644","language":[{"iso":"eng"}],"date_updated":"2026-01-16T08:59:03Z","year":"2025","title":"Ultraviolet Renormalization of Spin Boson Models I.

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."}],"project":[{"_id":"191","name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform"}],"publication":"arXiv:2509.10183","citation":{"ieee":"J.
