Trigonometric continuous-variable gates and hybrid quantum simulations of the sine-Gordon model
Journal of High Energy PhysicsHybrid qubit-qumode quantum computing platforms provide a natural setting for simulating interacting bosonic quantum field theories. However, existing continuous-variable gate constructions rely predominantly on polynomial functions of canonical ...

Bukhvostov–Lipatov model and quantum-classical duality
Nuclear Physics B, 2018 The Bukhvostov–Lipatov model is an exactly soluble model of two interacting Dirac fermions in 1+1 dimensions. The model describes weakly interacting instantons and anti-instantons in the O(3) non-linear sigma model. In our previous work [arXiv:1607.04839]

Advanced Functional Materials, EarlyView.A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells
Advanced Functional Materials, EarlyView.Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

Semiclassical monopole calculations in supersymmetric gauge theories [PDF]
, 2000 We investigate semiclassical contributions to correlation functions in N = 1 supersymmetric gauge theories. Our principal example is the gluino condensate, which signals the breaking of chiral symmetry, and should be exactly calculable, according to a ...

Gapless fracton quantum spin liquid and emergent photons in a 2D spin-1 model
Nature CommunicationsGapless fracton quantum spin liquids are exotic phases of matter described by higher-rank U(1) gauge theories, which host gapped and immobile fracton matter excitations as well as gapless photons.

Boundary quantum field theories perturbed by TT‾: Towards a form factor program
Nuclear Physics BOur understanding of irrelevant perturbations of integrable quantum field theories has greatly expanded over the last decade. In particular, we know that, from a scattering theory viewpoint at least, their effect is realised as a modification the two ...

Photon masses in the landscape and the swampland
Journal of High Energy Physics, 2019 In effective quantum field theory, a spin-1 vector boson can have a technically natural small mass that does not originate from the Higgs mechanism. For such theories, which may be written in Stückelberg form, there is no point in field space at which ...

Advanced Functional Materials, EarlyView.In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.
