Ginzton Lab: AMO on the Attosecond Scale

Topic: 
AMO on the Attosecond Scale
Abstract / Description: 

Please join us at Spilker room 232 every Monday afternoon from 4 pm for the AP 483 & Ginzton Lab, and AMO Seminar Series.
Refreshments begin at 4 pm, seminar at 4:15 pm

Light travels three Angstroms per attosecond, and electrons in molecular valence orbitals travel the same distance in a few hundred attoseconds, so there is strong motivation for methods to measure and control electron motion on this time scale. I'll discuss recent progress in this area.

SystemX Seminar: Rethinking the Functional Boundaries of Integrated Radio-Frequency Systems Enables New Wireless Communication Paradigms

Topic: 
Rethinking the Functional Boundaries of Integrated Radio-Frequency Systems Enables New Wireless Communication Paradigms
Abstract / Description: 

Mobile data traffic in 2014 was nearly 30 times the size of the entire global Internet in 2000. Next generation wireless networks are targeting 1000x increase in capacity to meet the insatiable demand for more data. Such a tremendous increase in wireless data will require a complete rethinking of today's wireless communication systems and networks from the physical layer to the network and application layer.

My research program at Columbia University is focused on transformative radio-frequency (RF) and millimeter-wave (mmWave) circuit design techniques that enable new system architectures that challenge the traditional functional boundaries (antenna/RF/analog/digital) of wireless communication systems and specifically enable advanced signal processing techniques at RF, thus enabling new wireless communication paradigms in close collaboration with communications, signal processing and network theorists.

In this talk, I will focus on recent research in CoSMIC lab in this space. I will touch upon our work on energy-efficient and high-power millimeter-wave CMOS circuits that have drawn interest for next-generation 5G cellular communications. The bulk of this talk will focus on our work on enabling full-duplex wireless communication, where transmitters and receivers operate at the same frequency at the same time, thus potentially doubling data throughput, promoting more flexible spectrum usage, and enabling solutions to several network problems. The fundamental challenge in full duplex is the tremendous transmitter self-interference at the receiver, which can be one trillion times more powerful than the desired signal and must be dealt with in all domains. This powerful self-interference is susceptible to uncertainties of the wireless channel (for instance, frequency selectivity and time variance) and the imperfections of the transceiver electronics (nonlinear distortion and phase noise to name a few), making it even harder to deal with. I will discuss several generations of fully-integrated CMOS transceiver ICs with self-interference cancellation that leverage circuit design innovations to enable advanced yet robust signal processing such as noise cancellation, distortion cancellation and wireless channel equalization in the RF and electromagnetic (i.e. antenna) domains and achieve the challenging performance required. I will also briefly touch upon our collaborative work with network theorists to determine the rate gains that are possible under various full duplex scenarios based on realistic physical layer models that we developed. Finally, I will end this talk with a brief description of our ongoing and future work on other emerging wireless communication paradigms.

Applied Physics/Physics Colloquium: Tensor Network Renormalization

Topic: 
Tensor Network Renormalization
Abstract / Description: 

The renormalization group (RG), one of the conceptual pillars of statistical mechanics and quantum field theory, explores how the behavior of an extended system depends on the scale of observation. Important notions such as universality, criticality or stability of phases are explained in terms of the existence of fixed-points of the RG flow. On the other hand, studies of entanglement in the context of quantum information have resulted in the development of tensor networks, a framework to efficiently describe many-body wave-functions. In this Colloquium I will review a decade-long research program based on applying tensor networks to the renormalization group. This program has produced a novel non-perturbative, real-space RG approach and the multi-scale entanglement renormalization ansatz (MERA), currently of interest in a wide range of research areas, from statistical mechanics to condensed matter and quantum field theory, from holography in quantum gravity, to error correction in classical and quantum information theory.

Beyond prosthetics: brain-machine interfaces as common clinical tools

Topic: 
Beyond prosthetics: brain-machine interfaces as common clinical tools
Abstract / Description: 

To date, the scope of brain-machine interfaces (BMIs) has largely been to restore lost function to people with paralysis stemming from conditions such as neurodegenerative disease and spinal cord injury. These systems interface with the brain using neurosurgically implanted electrodes, measure the voltage of individual and groups of neurons, and translate these measurements via a decoding algorithm to control an end effector such as a computer cursor. I will discuss work performed in preclinical rhesus models that led to the highest performing communication BMI demonstrated to date, as well as recent results of an ongoing clinical trial where these preclinical algorithmic innovations have been successfully translated to a human participant, again yielding the highest communication rates of any known clinical BMI.

The example of prosthetics is just one important application leveraging intracortical BMIs as a platform for accurately assessing and acting on the neural state. However, these measurements could play a crucial role in the diagnosis and management of a wide range of neurological and psychiatric diseases and disorders, ranging from stroke and epilepsy to depression and unconsciousness. Just as EEG recordings help localize seizures both temporally and spatially, and MRI imaging provides morphological and gross functional evaluations of the brain, BMI measurements may reveal previously unrecognized disease-specific adulterations in the neural state. Not only could this aid in forming better prognoses, but may also lead to interventions to prevent or alleviate undesirable symptoms and improve rehabilitation. In this manner, the utility of BMIs could extend far beyond communication or motor prosthetics to become an indispensable clinical tool in the treatment of brain disorders. I will discuss the emerging potential and key initial steps of this new class of medical system.

SystemX Seminar: Energy Efficiency and Conversion in 1D and 2D Electronics

Topic: 
Energy Efficiency and Conversion in 1D and 2D Electronics
Abstract / Description: 

We review our recent studies concerning the heterogeneous integration of nanomaterials for low-power electronics and energy harvesting applications. Through careful transport studies of two-dimensional (2D) devices based on graphene and MoS2, we have uncovered details regarding their physical properties and band structure. We have investigated thermoelectric effects in graphene transistors and phase-change memory (PCM) elements for low-power electronics. We found that low-power transistors and memory could be enhanced by built-in thermoelectric effects which are particularly pronounced at nanometer length scales. We have also examined energy harvesting using composites based on one-dimensional (1D) carbon nanotubes, and uncovered both the lower (diffusive) and upper (ballistic) limits of heat flow in 1D and 2D nanomaterials. Our results suggest fundamental limits and new applications that could be achieved through the co-design and heterogeneous integration of 1D and 2D nanomaterials.
