Quantum Gases of Dipoles, Quadrupoles and Octupoles in Gross–Pitaevskii Formalism with Form Factor
, 2020 Here, classical and quantum field theory of dipolar, axisymmetric quadrupolar and octupolar Bose gases is considered within a general approach. Dipole, axisymmetric quadrupole and octupole interaction potentials in the momentum representation are ...

SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications
Advanced Intelligent Systems, EarlyView.To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva
Advanced NanoBiomed Research, EarlyView.A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

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-

Aspects of hydrodynamics in AdS/CMT [PDF]
, 2013 Condensed matter theory is the study of systems at finite density. In this thesis we will attempt to argue that gauge-gravity dualities can give deep and meaningful insights into the behaviour of strongly coupled condensed matter systems. The first three

Quantum quenches in 1D Bose Gases: Glimmers of Quantum KAM
, 2014 Using a numerical renormalization group based on exploiting an underlying exactly solvable non-relativistic theory, we study the out-of-equilibrium dynamics of a 1D Bose gas (as described by the Lieb-Liniger model) released from a parabolic trap into a ...

Ultracold Quantum Gases and Lattice Systems: Quantum Simulation of Lattice Gauge Theories
, 2013 Abelian and non-Abelian gauge theories are of central importance in many areas of physics. In condensed matter physics, AbelianU(1) lattice gauge theories arise in the description of certain quantum spin liquids.

Simulating ultracold matter: horizons and slow light
, 2007 This thesis explores the links between different ways of modelling the physical world. Finite difference numerical simulations may be used to encode the behaviour of physical systems, allowing us to gain insight into their workings and even to predict ...

Dynamic Covalent Radical Recombination for the Assembly of Tuneable Responsive Porous Organic Cages
Angewandte Chemie International Edition, EarlyView.Dynamic covalent chemistry (DCC) based on reversible radical recombination enables the assembly of responsive, C─C‐linked organic cages. Substituent‐controlled aryldicyanomethyl radicals form discrete, porous architectures with tuneable topology of Tri2 and Tri4 cages, gas selectivity, chromism, and self‐healing behaviour, establishing radical‐based ...
