Exchange field enhanced upper critical field of the superconductivity in compressed antiferromagnetic EuTe2
Understanding the interplay between superconductivity and magnetism has been a longstanding challenge in condensed matter physics. Here we report...

Planckian dissipation and non-Ginzburg-Landau type upper critical field in Bi2201
Resistivity and Hall effect measurements have been carried out on a micro-fabricated bridge of Bi2201 single crystal at low temperatures down to 0.4...

The two upper critical dimensions of the Ising and Potts models
We derive the exact actions of the Q -state Potts model valid on any graph, first for the spin degrees of freedom, and second for the...

Refined Universality for Critical KCM: Upper Bounds
We study a general class of interacting particle systems called kinetically constrained models (KCM) in two dimensions. They are tightly linked to...

Nearly critical superfluid: effective field theory and holography
We study a nearly critical superfluid system from two complementary approaches. Within the first approach, we formulate a Schwinger-Keldysh effective...

Theoretical Investigation of Temperature Dependence of Upper Critical Magnetic Field (HC2) in Two-Band Iron-Based Superconductor Ba1-xRbxFe2As2
The current research work deals with the theoretical investigation of the temperature dependence of upper critical magnetic field ( H C 2 ) in two-band...

Magnetic field enhanced critical current and subharmonic structures in dissipative superconducting gold nanowires
Quantum breakdown of superconductivity in low-dimensional superconducting systems has attracted enormous attention due to the underlying fluctuation....

On the Derivation of Mean-Field Percolation Critical Exponents from the Triangle Condition
We give a new derivation of mean-field percolation critical behaviour from the triangle condition that is quantitatively much better than previous...

Normal State Properties and Upper Critical Magnetic Field in Three-dimensional Polycrystalline Niobium Films
Three-dimensional (3D) niobium (Nb) films have been deposited on quartz substrates by changing substrate temperature or film thickness. The...

The critical current density of iron-based superconductors under magnetic field
AbstractThe time-dependent Ginzburg–Landau Lawrence–Doniach model with thermal fluctuations is used to investigate the critical current density. We...

Topological excitations in statistical field theory at the upper critical dimension
We present a high-precision Monte Carlo study of the classical Heisenberg model in four dimensions. We investigate the properties of monopole-like...

Critical active dynamics is captured by a colored-noise driven field theory
Active matter may sometimes behave almost indistinguishably from equilibrium matter. This is particularly evident for some particle-based models and...

The ZZ annulus one-point function in non-critical string theory: A string field theory analysis
We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the...

Study on the Field-Dependent Activation Energy, U(H,T), Upper Critical Field, Hc2(0), and Irreversibility Field, µ0Hirr, Properties of Superconducting Single-Crystal Ag-Added Fe(Se, Te) Alloys
Superconducting FeTe 0.5 Se 0.5 + Ag single-crystal samples with 0, 1, 2, 3, 4, and 5% Ag concentrations were prepared successfully by the self-flux...

On the density of 2D critical percolation gaskets and anchored clusters
We prove a formula, first obtained by Kleban, Simmons and Ziff using conformal field theory methods, for the (renormalized) density of a critical...

Finite-temperature critical behaviors in 2D long-range quantum Heisenberg model
The Mermin-Wagner theorem states that spontaneous continuous symmetry breaking is prohibited in systems with short-range interactions at spatial...
