Optical tweezers are an essential tool in a broad range of fields, from biophysics to soft-matter and statistical physics. Using a feedback-based trap that can produce complex, time-dependent potential landscapes, we can experimentally realize situations in thermodynamics, such as finite-time bit-erasure, that were previously only thought experiments. To obtain quantitative results, however,...
Vertically stacked heterostructures of two-dimensional materials provide a platform for realizing novel electronic states due to proximity effects. In particular, moiré patterns in two-dimensional material heterostructures have been shown to create flat bands that favor the occurrence of correlated electronic states. In this work, we use scanning tunneling microscopy and spectroscopy to study...
Two dimensional (2D) materials are tempting for nano-electromechanical systems (NEMS), as they are atomically thin, have low mass and high flexibility. 2D materials have tunable optical and electronic properties, and can display other exotic properties, such as superconductivity. Over the last decade, scientists have begun stacking 2D materials into heterostructures that have desirable...
Introduction: Graphene is a promising nanomaterial for chemical sensors or biosensors, but functionalization of its surface is usually necessary to ensure specific interactions with the chosen analyte. Among functionalization strategies, covalent adducts are most likely to ensure stability of the functionalization during multiple flow cycles. In particular, aryldiazonium salts are known...
Several parallels can be drawn between the perovskite iridate Sr$_2$IrO$_4$, and the high Tc cuprates. Although the low energy spectrum of Sr$_2$IrO$_4$ includes the three t$_{2g}$ bands, strong spin-orbit coupling splits the bands such that one can write an effective one-orbital J=1/2 model, in analogy with the single orbital of the cuprates. This has led to predictions of d-wave...
According to the laws of thermodynamics, a closed many-body system is expected to follow a chaotic evolution and reach a state of thermal equilibrium. The issue arises when one asks for a quantum picture. Indeed quantum mechanics strictly prohibits chaotic dynamics, and some quantum systems have been discovered to resist thermalization.
To solve this paradox, entanglement is believed to be a...
Quantum confinement and manipulation of charge carriers are critical for achieving devices practical for various quantum technologies. Atomically thin transition metal dichalcogenides (TMDCs) have attractive properties such as spin-valley locking, large spin-orbit coupling and high confinement energies which provide a promising platform for novel quantum technologies. In this talk, we present...
