Summary and Outlook
In this thesis we have presented an ab initio theory for the calculation of pair- and multi-spin, or multi-site, magnetic interactions in magnetic...

Phonons, Magnons, and Excitons in the Noncentrosymmetric Magnetoelectric Antiferromagnet CuB2O4
AbstractIn the last two decades copper metaborate CuB 2 O 4 with a unique noncentrosymmetric crystal structure has become the subject of active...

Finite Temperature Phase Diagrams of the Mixed Spin-1 and Spin-2 Blume–Capel Model by Renormalization Group Approach
The Blume–Capel model with mixed spins S = 1 and S = 2, on d -dimensional hypercubic lattice, is studied using the real space renormalization group...

Quantum phase transition and entanglement entropy in the Dicke model with a squeezed light
AbstractSuperradiant phase transition and entanglement entropy in the Dicke model with a squeezed light are investigated. We find a special rotation...

Classification of equation of state in relativistic heavy-ion collisions using deep learning
Convolutional Neural Nets, which is a powerful method of Deep Learning, is applied to classify equation of state of heavy-ion collision event...

Landau Theory of Causal Dynamical Triangulations
Understanding the continuum limit of a theory of discrete random geometries is a beautiful but difficult challenge. In this optic, we review here the...

Triple high energy nuclear and hadron collisions - a new method to study QCD phase diagram at high baryonic densities
We propose an entirely new method to study the phase diagram of strongly interacting matter by means of scattering the two colliding beams at the...

Effects of Local Fields in a Dissipative Curie-Weiss Model: Bautin Bifurcation and Large Self-sustained Oscillations
We modify the spin-flip dynamics of a Curie-Weiss model with dissipative interaction potential [

Competitive metastable behaviours of surface and bulk in Ising ferromagnet
The reversal of magnetisation has been studied in a three-dimensional Ising ferromagnet by Monte Carlo simulation with Metropolis single spin flip...

Off-equilibrium non-Gaussian fluctuations near the QCD critical point: an effective field theory perspective
The non-Gaussian fluctuations of baryon density are sensitive to the presence of the conjectured QCD critical point. Their observational consequences...

Dual EFT bootstrap: QCD flux tubes
We develop a bootstrap approach to Effective Field Theories (EFTs) based on the concept of duality in optimisation theory. As a first application, we...

Towards learning optimized kernels for complex Langevin
We present a novel strategy aimed at restoring correct convergence in complex Langevin simulations. The central idea is to incorporate...

Pion screening mass at finite chemical potential
We present a method to compute the responses of meson screening masses to the chemical potential by Taylor expanding the correlator using lattice QCD...

Criticality-related fundamental bases for new generations of gas–liquid, liquid–liquid, and liquid (LE) extraction technologies
AbstractThe report presents experimental results, which can be considered as the reference for innovative generations of supercritical fluids (SCF),...

The SU(3) spin model with chemical potential by series expansion techniques
The SU(3) spin model with chemical potential corresponds to a simplified version of QCD with static quarks in the strong coupling regime. It has been...

Critical 1- and 2-point spin correlations for the O(2) model in 3d bounded domains
We study the critical properties of the 3 d O (2) universality class in bounded domains through Monte Carlo simulations of the clock model. We use an...
