Critical Theory of Non-Fermi Liquid Fixed Point in Multipolar Kondo Problem

open access: yesPhysical Review X, 2020
When the ground state of a localized ion is a non-Kramers doublet, such localized ions may carry multipolar moments. For example, Pr^{3+} ions in a cubic environment would possess quadrupolar and octupolar, but no magnetic dipole, moments.

Deformation techniques in metric critical point theory

open access: yesAdvances in Nonlinear Analysis, 2013
We propose a synthetic and self-contained treatment of the main deformation results of critical point theory, for continuous functionals defined on metric spaces.

The Use of Cerami Sequences in Critical Point Theory

open access: yesAbstract and Applied Analysis, 2007
The concept of linking was developed to produce Palais-Smale (PS) sequences G(uk)→a, G'(uk)→0 for C1functionals G that separate linking sets. These sequences produce critical points if they have convergent subsequences (i.e., if G satisfies the PS ...

Multiple solutions for systems of multi-point boundary value problems [PDF]

open access: yesOpuscula Mathematica, 2013
In this paper, we establish the existence of at least three solutions of the multi-point boundary value system \[\left\{\begin{array}{ll} -(\phi_{p_i}(u'_{i}))'=\lambda F_{u_{i}}(x,u_{1},\ldots,u_{n}),\ t\in(0,1),\\ u_{i}(0)=\sum_{j=1}^m a_ju_i(x_j ...

Infinitely Many Periodic Solutions to Delay Differential Equations via Critical Point Theory

open access: yesAbstract and Applied Analysis, 2013
By the critical point theory, infinitely many 4σ-periodic solutions are obtained for the system of delay differential equations ẋt=-f(x(t-σ)), where σ∈(0,+∞) and f∈C(ℝn,ℝn).

Periodic Solutions for Semilinear Fourth-Order Differential Inclusions via Nonsmooth Critical Point Theory

open access: yesJournal of Function Spaces, 2014
Three periodic solutions with prescribed wavelength for a class of semilinear fourth-order differential inclusions are obtained by using a nonsmooth version critical point theorem. Some results of previous related literature are extended.

Off-equilibrium non-Gaussian fluctuations near the QCD critical point: an effective field theory perspective

open access: yesJournal of High Energy Physics, 2022
The non-Gaussian fluctuations of baryon density are sensitive to the presence of the conjectured QCD critical point. Their observational consequences are crucial for the ongoing experimental search for this critical point through the beam energy scan ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.
