Floquet‐Engineered Noise‐Resilient Terahertz Receiver with Modular Phased Array Architecture for Scalable Chip‐Scale Communication

Advanced Photonics Research, Volume 6, Issue 11, November 2025.
Overcoming the bandwidth, latency, and power constraints of wired interconnects in multicore processing units, this work introduces a terahertz wireless solution featuring a dual‐carrier modular phased‐array transmitter and a novel 2D semiconductor quantum‐well nanoreceiver.

Reconstructing S-matrix Phases with Machine Learning

Journal of High Energy Physics
An important element of the S-matrix bootstrap program is the relationship between the modulus of an S-matrix element and its phase. Unitarity relates them by an integral equation.

Programmable Functional Connectivity and Synchronous Activity in Resistive Switching Self‐Assembled Nanostructured Networks

Small Structures, Volume 6, Issue 11, November 2025.
The adaptive and controllable functional connectivity of self‐assembled nanostructured materials has been investigated by a combined approach based on microthermography and electrical measurements. Interacting active regions and synchronous resistive switching activity characterize the network dynamics at different scales.

How to define the moving frame of the Unruh-DeWitt detector on manifolds

Journal of High Energy Physics
The physical phenomena seen by an observer are defined for a local inertial system that is subjective to the observer. Such a coordinate system is called a “moving frame” because it changes from time to time.

|Vub| determination and testing of lepton flavour universality in semileptonic Bc → D(∗) decays

Journal of High Energy Physics, 2020
In light of prospects for measurements of B c  → D (∗) lv decays in the upcoming Upgrade II of the LHC, we show that by using calculated B c  → D (∗) form factors a competitive extraction of the |V ub | CKM matrix element from the B c → Dμ v ¯ μ $$ {B}_c\

Revisiting Coleman-de Luccia transitions in the AdS regime using holography

Journal of High Energy Physics, 2021
Coleman-de Luccia processes for AdS to AdS decays in Einstein-scalar theories are studied. Such tunnelling processes are interpreted as vev-driven holographic RG flows of a quantum field theory on de Sitter space-time.

Large-order behavior and nonperturbative effects [PDF]

Nuclear Physics B, 1995
Abstract We consider the energy-dependence of the large-order behavior of forward scattering amplitudes in theories having explicit mass parameters and instanton solutions. We show that in weak coupling theories the exponential part of the Espinosa-Ringwald type cross section can be determined by taking the minimum element of the perturbative series,

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, Volume 78, Issue 10, Page 2001-2118, October 2025.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

1 PHz of Coherent Bandwidth from a Compact Fiber Device

Laser &Photonics Reviews, Volume 19, Issue 19, October 7, 2025.
A coherent comb spectrum with an unprecedented bandwidth of 1 PHz, spanning from the deep ultraviolet (280 nm) to the mid‐infrared (2700 nm), is generated by a compact fiber device. The integrated, novel pulse purification technology enables broadband dispersion control and the synthesis of low‐noise, single‐cycle near‐infrared pulses with a clean ...

Analytic structure in the coupling constant plane in perturbative QCD

, 2003
We investigate the analytic structure of the Borel-summed perturbative QCD amplitudes in the complex plane of the coupling constant. Using the method of inverse Mellin transform, we show that the prescription dependent Borel-Laplace integral can be cast,
