Magneto-Inter-Subband Oscillations in GaAs quantum wells with three populated subbands placed in tilted magnetic fields.

William Mayer has made presentation of his research in condensed matter physics.  The magnetotransport of highly mobile two-dimensional electrons in wide GaAs single quantum wells with three populated subbands placed in tilted magnetic fields is studied. The bottoms of the lower two subbands have nearly the same energy while the bottom of the third subband has a much higher energy (E1 ≈ E2 <<E3). At zero in-plane magnetic fields, magnetointersubband oscillations (MISO) between the ith and j th subbands are observed.  An application of in-plane magnetic field produces dramatic changes in MISO and the corresponding electron spectrum. At small perpendicular magnetic fields the semiclassical regime of electron propagation is identified. In contrast, at strong magnetic fields relatively weak oscillating variations of the electron spectrum with the in-plane magnetic field are observed. At intermediate magnetic fields, the electron spectrum undergoes a transition between these two regimes through magnetic breakdown. In this transition regime MISO with odd quantum number k terminate, while MISO corresponding to even k evolve continuously into the high-field regime. These results are published in Physical Review B 93,115309 (2016). 

Session S51: Thermodynamic & Transport Properties of Semiconductors

Mishima (Univ. of Oklahoma); M.B. Santos (Univ. of Oklahoma); Javad Shabani (Graduate Center, CCNY CUNY) Quantum Hall states in strained InAs heterostructures

In a recent development it was realized that non-Abelian quasiparticles, parafermion zero-modes emerge at an interface between a superconductor and two dimensional electron system (2DES) in the quantum Hall regime. [1]. Unlike widely used GaAs systems, surface level pinning in InAs could allow for fabrication of transparent contacts to superconductors. However, no fractional quantum Hall state has been observed in InAs quantum wells so far. Whether this is due to the type of disorder present in the quantum well is not clear. In this work, we study the transport and dingle mobility of 2DESs confined to strained InAs quantum wells as a function of electron density and spacer thickness to the surface. We compare our results to early observation of fractional quantum Hall states in GaAs. [1] R. S. K. Mong, et al. Phys. Rev. X 4, 011036 (2014)

Session F51: 2DEG and Quantum Hall Effect


Jacob Henshaw (The Graduate Center, City College, CUN); Carlos Meriles (Graduate Center, CCNY CUNY) No title

The nitrogen-vacancy (NV) center in diamond is presently the focus of widespread attention for applications ranging from quantum information processing to nanoscale metrology. Of great utility is the ability to optically initialize the NV charge state, which has an immediate impact on the center's light emission properties. Here, we use two-color microscopy in NV-rich, type-1b diamond to demonstrate fluorescence-encoded long-term storage of classical information. As a proof of principle, we write, reset, and rewrite various patterns with 2-D binary bit density comparable to present DVD-ROM technology. The strong fluorescence signal originating from the diffraction-limited bit volume allows us to transition from binary to multi-valued encoding, which translates into a significant storage capacity boost. Finally, we show that our technique preserves information written on different planes of the diamond crystal and thus serves as a platform for three-dimensional storage. Substantial enhancement in the bit density could be achieved with the aid of super resolution microscopy techniques already employed to discriminate between NVs with sub-diffraction, nanometer accuracy, a regime where the storage capacity could exceed 1017 bytes/cm3

Summer

2014:

Harry Charalambous at University of Chicago: "Continuous Cryogenic He-3 Adsorption Pump" . "I did my REU at the University of Chicago. David Schuster was my advisor. He's a professor there who works on low temperature physics, namely circuit quantum electrodynamics using SQUIDS and on the effects of electrons on liquid helium. He's also taken to redesigning the dilution refrigerators used in labs to get to the millikelvin temperature range (he has 2 of them already).
 

2013:

Benjamin Diamond at CCNY, Quantum Mechanics workshop working with Dr. Brian Tiburzi and various other physics students I knew since before the workshop  It was taxing on the mind but I appreciated the experience

Tai-Danae Bradley at the Institute for Advanced Study (IAS) in Princeton, NJ, attending the IAS's annual 2-week long "Program for Women and Mathematics" which serves as a mentoring program for aspiring women mathematicians and seeks to shed light on the issues of gender imbalance in mathematics.  We attended daily lectures, research seminars, and colloquia on this year's topic - Combinatorics and Graph Theory.  Worked with other undergraduates, graduate students, post-docs and professional researchers from universities all over the US (and some from Europe).  It was really an unforgettable experience!

Tai-Danae Bradley at CCNY working on my honors research project in Number Theory (a branch of mathematics, my second major) and worked with Dr. Brooke Feigon (Math Dept.) and two other students (Yin Choi Cheng and Yan Fei Luo). We have compiled our results into a paper and submitted it to the undergraduate math journal "Involve." We are hoping to be published soon!  I feel better equipped for graduate work and have learned so much more than expected - not only new mathematics, but also some of the nuances of what it takes to be a truly successful researcher.

2010:

Alisa Agafonova, Undergraduate research for Professor Lia Krusin, City College, CUNY
"Production of nanoplate crystals of topological insulator Sb2Te3 by catalyst-free vapor-liquid-solid method. Study of the crystals using transmission electron microscopy."

2009:

"Stochastic Effects in Polymerization Dynamics"  Constructed a series of computational models, to analyze the dynamics of the polymerization process, using Kinetic Monte Carlo (Gillespie) algorithm for stochastic model, and the Master Equation to calculate the steady state length distribution.
