Strongly correlated ultracold bosons in an optical lattice
, 2012 In this thesis, we have investigated strongly correlated bosonic gases in an optical lattice, mostly based on a bosonic version of dynamical mean field theory and its real-space extension. Emphasis is put on possible novel quantum phenomena of these many-

Perturbative and non-perturbative studies in low dimensional quantum field theory [PDF]
, 2007 A relevant perturbation of a conformal field theory (CFT) on the half-plane, by both a bulk and boundary operator, often leads to a massive theory with a particle description in terms of the bulk S-matrix and boundary reflection factor R.

Quantum phases of supersymmetric lattice models
, 2010 We review recent results on lattice models for spin-less fermions with strong repulsive interactions. A judicious tuning of kinetic and interaction terms leads to a model possessing supersymmetry.

Journal of High Energy Physics, 2018 In this article we summarise our results from numerical simulations of N = 1 $$ \mathcal{N}=1 $$ supersymmetric Yang-Mills theory with gauge group SU(3). We use the formulation of Curci and Veneziano with clover-improved Wilson fermions.

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Advanced Functional Materials, EarlyView.Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

OTOC and quamtum chaos of interacting scalar fields
Journal of High Energy PhysicsDiscretizing the λϕ 4 scalar field theory on a lattice yields a system of coupled anharmonic oscillators with quadratic and quartic potentials. We begin by analyzing the two coupled oscillators in the second quantization method to derive several analytic

3d N = 4 $$ \mathcal{N}=4 $$ super-Yang-Mills on a lattice
Journal of High Energy Physics, 2018 In this paper we explore a new approach to studying three-dimensional N = 4 $$ \mathcal{N}=4 $$ super-Yang-Mills on a lattice. Our strategy is to complexify the Donaldson-Witten twist of four-dimensional N = 2 $$ \mathcal{N}=2 $$ super-Yang-Mills to make

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells
Advanced Functional Materials, EarlyView.ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Complex sine-Gordon theory: solitons, defects and boundaries [PDF]
, 2008 This thesis presents research into the properties and features of the complex sine- Gordon theory. The CSG theory is a dimensional integrable held theory that admits soliton solutions which carry a Noether charge due to the U(I) invariance of the theory.
