Surface coupling of NV centers over nanoscale lengths
Arsineh Apelian, Mariya Romanova, Vojtech Vlcek
Shallow nitrogen-vacancy (NV-) centers in diamond are among the most promising quantum sensors, offering high sensitivity and nanoscale spatial resolution. These systems are, howev…
Impact of Subsurface Oxygen on CO2 Charging Energy Changes in Cu Surfaces
Xiaohe Lei, Vojtech Vlcek
Subsurface oxygen in oxide-derived copper catalysts significantly influences CO activation. However, its effect on the molecular charging process, the key to forming the CO$_2^…
Delocalization of Quasiparticle Moiré States in Twisted Bilayer hBN
Arsineh Apelian, Annabelle Canestraight, Songyuan Liu +1
Twisted bilayers host many emergent phenomena in which the electronic excitations (quasiparticles - QPs) are closely intertwined with the local stacking order. By inspecting twiste…
Fidelity and variability in the interlayer electronic structure of the kagome superconductor CsV3Sb5
Aurland K. Watkins, Dirk Johrendt, Vojtech Vlcek +2
The AV3Sb5 (A = K, Rb, Cs) kagome materials host an interplay of emergent phenomena including superconductivity, charge density wave states, and non-trivial electronic structure to…
Disordered Hyperuniform Solid State Materials
Duyu Chen, Houlong Zhuang, Mohan Chen +3
Disordered hyperuniform (DHU) states are recently discovered exotic states of condensed matter. DHU systems are similar to liquids or glasses in that they are statistically isotrop…
Tuning the range separation parameter in periodic systems
Wenfei Li, Vojtech Vlcek, Helen Eisenberg +3
Kohn-Sham DFT with optimally tuned range-separated hybrid (RSH) functionals provides accurate and nonempirical fundamental gaps for a wide variety of finite-size systems. The stand…
Nonmonotonic band gap evolution in bent phosphorene nanosheets
Vojtech Vlcek, Eran Rabani, Roi Baer +1
Nonmonotonic bending-induced changes of fundamental band gaps and quasiparticle energies are observed for realistic nanoscale phosphorene nanosheets. Calculations using stochastic…
