Phases of two-dimensional spinless lattice fermions with first-quantized deep neural-network quantum states

First-quantized deep neural network techniques are developed for analyzing strongly coupled fermionic systems on the lattice. Using a Slater-Jastrow-inspired ansatz which exploits deep residual networks with convolutional residual blocks, we approximately ...

Controlling the Quantum Spin Hall Edge States in Two-Dimensional Transition Metal Dichalcogenides

Oleg Yazyev, Artem Pulkin

Two-dimensional transition metal dichalcogenides (TMDs) of Mo and W in their 1T' crystalline phase host the quantum spin Hall (QSH) insulator phase. We address the electronic properties of the QSH edge states by means of first-principles calculations perfo ...

Quantum state manipulation of single atom magnets using the hyperfine interaction

Harald Brune, François Patthey, Edgar Fernandes, Donat Fabian Natterer, Patrick Robert Forrester, Dante Philippe Sblendorio

The magnetic quantum states of holmium single atom magnets on MgO(100) have proven extremely robust when exposed to high magnetic fields and temperatures up to 35 K. Here we address the stability of Ho at small magnetic fields, where the hyperfine interact ...

Differential steric effects in the inelastic scattering of NO(X) plus Ar: spin-orbit changing transitions

Sean Dennis Steven Gordon

Spin-orbit changing transitions for bond-axis oriented collisions of NO(X) with Ar have been investigated with full quantum state selection via a crossed molecular beam experiment at collision energies of 532 cm(-1) and 651 cm(-1). NO(X) molecules were sel ...

Two-dimensional Rashba metals: Unconventional low-temperature transport properties

Claudio Grimaldi

Rashba spin-orbit coupling emerges in materials lacking of structural inversion symmetry, such as heterostructures, quantum wells, surface alloys and polar materials, just to mention few examples. It yields a coupling between the spin and momentum of elect ...

Homonuclear ADAPT: A general preparation route to long-lived nuclear singlet order

Gabriele Stevanato

We introduce a simple strategy to access and readout nuclear singlet order based on the alternate repetition of hard pulses and delays. We demonstrate the general applicability of the method by accessing nuclear singlet order in spin systems characterized ...

Direct measurement of the spectral dependence of Lamb coupling constant in a dual frequency quantum well-based VECSEL

Elyahou Kapon, Alexandru Mereuta, Andrei Caliman, Salvatore Pes

Spectral dependence of Lamb coupling constant C is experimentally investigated in an InGaAlAs Quantum Wells active medium. An Optically-Pumped Vertical-External-Cavity Surface-Emitting Laser is designed to sustain the oscillation of two orthogonally polari ...

Terahertz-optical properties of a bismuth ferrite single crystal

Henrik Moodysson Rønnow, Jean-Philippe Ansermet, Marcin Bialek

Transmission through a (100)-oriented single crystal of bismuth ferrite (BiFeO3) was studied at frequencies of 0.485-0.765 THz with a continuous-wave source and in the temperature range of 30-350 K as a function of polarization angle. The fine splitting of ...
