LaAlO${}_3$/SrTiO${}_3$ interfaces are a nice example of a two-dimensional electron gas, whose carrier density can be varied by top- and back-gating techniques. Due to the electron confinement near the interface, the two-dimensional band structure is split int...

A self-consistent two-gap $\gamma$ -model is used to quantitatively describe several thermodynamic properties of MgB ${}_2$ superconductor. The superconducting coupling matrix, ${\nu }_{ij}$ , was obtained from the fitting of the superflui...

While it is known that the amplification of the superconducting critical temperature T_C is possible in a system of multiple electronic components in comparison with a single component system, many different road maps for room temperature superconduct...

Low-temperature superconductivity has been known since 1957 to be described by BCS theory for effective single-band metals controlled by the density of states at the Fermi level, very far from band edges, the electron–phonon coupling constant l...

A new possible scenario for the origin of the molecular collective behaviour associated with the emergence of living matter is presented. We propose that the transition from a non-living to a living cell could be mapped to a quantum transition to a c...

The temperature dependence of the two superconducting gaps in pressurised $H_{3}S$ at 155 GPa with a critical temperature of 203 K has been determined using a data analysis of the experimental curve of the upper critical magnetic field as a function of te...

While the search for new high-temperature superconductors had been driven by the empirical “trials and errors” method for decades, we now report the synthesis of Artificial High-T_c Superlattices (AHTS) designed by quantum mechanics theory at the nano...

This modelling work concerns the effects of the interference between two partial subband condensates in a quasi-one-dimensional superconducting superlattice. The iterative under-relaxation with phase control method is used to solve Bogoliubov–d...

The iron-based superconductors (IBSs) of the recently discovered 1144 class, unlike many other IBSs, display superconductivity in their stoichiometric form and are intrinsically hole doped. The effects of chemical substitutions with electron donors a...

Inspired by experiments manifesting unconventional metallic behavior in ${\mathrm{MoO}}_{2\pm \delta }$ and superconductivity in ${\mathrm{K}}_x$${\mathrm{MoO}}_{2-\delta }$, we present $t_{2g}$-DFT+DMFT results for monoclinic ${\mathrm{MoO}}_2$. We unearth the role played by multi-orbital, many-particle...

A method is proposed to extend the zero-temperature Hall-Klemm microscopic theory of the Knight shift K in an anisotropic and correlated, multi-band metal to calculate $K\left(T\right)$ at finite temperatures T both above and into its superconducting s...

This review covers several recent developments in the physics of dense QCD with an emphasis on the impact of multiple phase transitions on astrophysical manifestations of compact stars. To motivate the multi-phase modeling of dense QCD and delineate...

LK-99, with chemical formula Pb_10−xCu_x(PO₄)₆O, was recently reported to be a room-temperature superconductor. While this claim has met with little support in a flurry of ensuing work, a variety of calculations (mostly based on density-functiona...

Quantum machine learning (QML) integrates quantum computing with classical machine learning. Within this domain, QML-CQ classification tasks, where classical data is processed by quantum circuits, have attracted particular interest for their potentia...
