Abstract The development of magnetocaloric materials with a significantly enhanced volumetric cooling capability is highly desirable for the application adiabatic demagnetization refrigerators in confined spatial environments. Here, thermodynamic characteristics magnetically frustrated spin‐7/2 Gd 9.33 [SiO 4 ] 6 O 2 presented, which exhibits strongly correlated spin disorder below ≈1.5 K. A quantitative model proposed to describe magnetization results by incorporating nearest‐neighbor...
The non-Bloch topology leads to the emergence of various counterintuitive phenomena in non-Hermitian systems under open boundary condition, which can not find a counterpart Hermitian systems. However, system without chiral symmetry, being ubiquitous nature, exploring its has so far eluded experimental effort. Here, by introducing concept nonchiral invariants, we theoretically predict and experimentally identify topological phase diagram one-dimensional (1D) symmetry discrete-time nonunitary...

A crucial ingredient our model is rotating external field generates direction-dependent two-body effective attraction. Experimental signatures are predicted for cold gases radio-frequency spectroscopy. The finite diagram...

We propose an experimental protocol to study $p$-wave superfluidity in a spin-polarized cold Fermi gas tuned by $s$-wave Feshbach resonance. A crucial ingredient is add quasi-one-dimensional optical lattice and tune the fillings of two spins $s$ $p$ band, respectively. The pairing order parameter confirmed inherit symmetry its center-of-mass motion. find that it can further develop into state unexpected $\ensuremath{\pi}$-phase modulation broad regime. Experimental signatures are predicted...

Using the measured Capacitance-Voltage and Current-Voltage characteristics of rectangular AlN/GaN Heterostructure Field-Effect Transistors (HFETs) with different Schottky areas, we found that after device processing polarization Coulomb field (PCF) scattering is induced has an important influence on two-dimensional electron gas mobility. Moreover, it was also PCF enhanced mobility in HFETs compared to AlGaN/AlN/GaN HFETs. This attributed large lattice mismatch between AlN GaN necessitating a...

As result, critical density mechanical collapse smaller than that estimated in With included, new functional proposed trapped system, and its property explored.
Quantum spin models with spatially dependent interactions, known as compass models, play an important role in the study of frustrated quantum magnetism. One example is Kitaev model on honeycomb lattice spin-liquid (SL) ground states and anyonic excitations. Another geometrically 120° same whose state has not been unambiguously established. To generalize beyond exactly solvable limit connect it other we propose a new model, dubbed 'the tripod model', which contains continuum compass-type...
Chiral magnetism is a fascinating quantum phenomena that has been found in low-dimensional magnetic materials. It not only interesting for understanding the concept of chirality, but also important potential applications spintronics.

In a dipolar Fermi gas, the dipole-dipole interaction between fermions can be turned into Ising pseudospins in presence of an ac electric field. When trapped two-dimensional optical lattice, this gas has very rich phase diagram at zero temperature, due to competition antiferromagnetism and superfluidity. At half-filling, antiferromagnetic state is favored ground state. The superfluid appears as smaller filling factor. there phase-separated region. order parameter display different symmetries...
