Laser &Photonics Reviews, Volume 18, Issue 7, July 2024.A regenerative Yb:YAG thin‐disk amplifier drives nonlinear parametric downconversion, delivering femtosecond mid‐infrared pulses with electric field amplitudes found at submolecular dimensions of matter. The high repetition rate, versatility, beam quality, and passive phase stability of the system enable advanced spectroscopic techniques such as ...

Solving the 2D SUSY Gross-Neveu-Yukawa model with conformal truncation
Journal of High Energy Physics, 2021 We use Lightcone Conformal Truncation to analyze the RG flow of the two-dimensional supersymmetric Gross-Neveu-Yukawa theory, i.e. the theory of a real scalar superfield with a ℤ2-symmetric cubic superpotential, aka the 2d Wess-Zumino model.

Instanton Screening in the Nonperturbative Gluodynamics [PDF]
arXiv, 1999 The gluon fields screening in the stochastic vacuum of gluodynamics is studied. The effective action is derived for the instanton interacting with nonperturbative fields. Quantum nonperturbative effects are shown to affect greatly the shape of instanton.

Nonperturbative Zou-Wang-Mandel effect
Physical Review AThe Zou-Wang-Mandel (ZWM) effect is a remarkable consequence of photon indistinguishability and continuous-variable entanglement in which an optical phase shift is imprinted on photonic modes associated with optical paths that that do not pass through the phase shift source.

Nonperturbative Effects on the String World Sheet (Ii)
Nuclear Physics B, 1987 We show that the space-time superpotential, which is known to receive no string theoretic corrections in finite orders in α′, is modified by world-sheet instantons. This has a number of interesting consequences for the physics of compactification schemes which lead to low-energy supersymmetry.

Resurgent aspects of applied exponential asymptotics
Studies in Applied Mathematics, Volume 152, Issue 3, Page 974-1025, April 2024.Abstract In many physical problems, it is important to capture exponentially small effects that lie beyond‐all‐orders of an algebraic asymptotic expansion; when collected, the full asymptotic expansion is known as a trans‐series. Applied exponential asymptotics has been enormously successful in developing practical tools for studying the leading ...

Effective Average Actions and Nonperturbative Evolution Equations [PDF]
arXiv, 1996 The effective average actions for gauge theories and the associated nonperturbative evolution equations which govern their renormalization group flow are reviewed and various applications are described. As an example of a topological field theory, Chern-Simons theory is discussed in detail.

Theory and modeling of nonperturbative effects at high acoustic energy densities in thermoviscous acoustofluidics [PDF]
arXiv, 2021 A theoretical model of thermal boundary layers and acoustic heating in microscale acoustofluidic devices is presented. It includes effective boundary conditions allowing for simulations in three dimensions. The model is extended by an iterative scheme to incorporate nonlinear thermoviscous effects not captured by standard perturbation theory. The model

Tadpole diagrams in constant electromagnetic fields
Journal of High Energy Physics, 2017 We show how all possible one-particle reducible tadpole diagrams in constant electromagnetic fields can be constructed from one-particle irreducible constant-field diagrams.

What can be measured asymptotically?
Journal of High Energy PhysicsWe consider asymptotic observables in quantum field theories in which the S-matrix makes sense. We argue that in addition to scattering amplitudes, a whole compendium of inclusive observables exists where the time-ordering is relaxed.
