A lattice of interacting Majorana modes can occur in a superconducting film on a topological insulator in a magnetic field. The phase diagram as a function of interaction strength for the square lattice was analyzed recently using a combination of mean field theory and field theory and was found to include second order phase transitions. One of these corresponds to...

Large spin-orbit coupling makes the magnetic eigenstate of the total angular momentum state with an admixed spin state and induces unusual magnetic behaviors. In cooperation with the crystal field, it could introduce the Kramers doublet in the magnetic ion site. Then the magnetism is described with the so-called spin-orbit coupled isospin 1/2, and the system often displays novel quantum magnetism...

In the first part [1] I will show that electron-magnon interaction delocalizes the particle in a system with strong charge disorder. The analysis is based on results obtained for a single hole in the one–dimensional t–J model. Unless there exists a mechanism that localizes spin excitations, the charge carrier remains delocalized even for a very strong charge disorder and shows...

Charge density wave (CDW) order has recently been revealed as a central feature of the cuprate phase diagram, co-existing and competing with superconductivity in underdoped cuprates. Intriguingly, the CDW order has been proposed to exhibit a novel d form factor orbital symmetry — a quadrupolar modulation of the charge on the oxygen atoms surrounding each Cu site — evidence...

Topological Semimetals, such as Dirac and Weyl semimetals have sparked a new recent excitement in condensed matter physics. In this talk, I will argue that the rules and laws we know from inorganic chemistry are extremely useful to find and design new topological semimetals. Chemists have an on often underestimated predictive power of exotic physical properties. I will introduce how...

Among various techniques available for making single crystals, optical image floating zone crystal growth has been recognized as a leading tool for the production of ultrahigh-purity single crystals. High pressure of gas provides an additional advantage to the floating zone crystal growth in twofold: (1) it can suppress the evaporation of volatile components, and (2) it can generate high activity...

Micro/Nano scale device fabrication requires advanced fabrication techniques in a cleanroom environment. Electron beam lithography (EBL) is one of the widely used, critical and flexible tool for sub-micron resolution patterning.
Raith/Vistec EBPG5000+ES EBL system is the flagship micro-nano lithography tool at Sabanci University Nanotechnology Research and Application Center (SUNUM). System provides 100kV patterning of 10 nm scale devices over...
Speaker: Dr. V.E. Shapiro
Time: May 29, 2018, 2:00 PM - 3:00 PM
Location: BRIM 311
Thus far quantum mechanism is commonly treated in both fundamental and applied matters as an ultimate unifying guideline of nature inherent in ambient noise impact. For arguments sake I formulate a no go theorem and deduce its evidence with topology arguments disproving the quantum principle of the realm everywhere, both in and off detailed balance, and discuss principles of atomism...
Speaker: Julio A. Rodríguez Manzo, Application Scientist at Hummingbird Scientific

I will present an overview of sample holders that broaden the stimuli “knobs”—environment, temperature, electric potential, etc.—that can be used to observe, with high-spatial resolution, a specimen or device in an electron or x-ray microscope under operating conditions. For example, with a standard transmission electron microscopy (TEM) sample holder specimens are observed at low pressures (~ 10 -7 mbar) that...
