CM Seminar: Renormalization group analysis of phase transitions in the two dimensional Majorana-Hubbard model

21 Aug2018

Speaker: Kyle Wamer

Time: Tues, August 21, 2:00 - 3:00 pm

Location: BRIM 311

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...

Seminar: Unusual Magnetic Behaviors involving Large Spin-Orbit Coupling

02 Aug2018

Speaker: Jae-Hoon Park, Max Planck POSTECH Center for Complex Phase Materials

Time: Aug 2, 2018 :: 11:00AM - 12:00PM

Location: Brimacombe 311

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...

Seminar: Charge vs. Spin Disorder in a Correlated Electron System

16 Jul2018

Speaker: Janez Bonca, Faculty of Mathematics and Physics University of Ljubljana and J. Stefan Institute

Location: BRIM 311

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...

Seminar: Orbital symmetry of Charge Density Wave Order in Cuprate Superconductors

12 Jul2018

Speaker: David Hawthorn, University of Waterloo

Time: Jul 12, 2018 :: 2:00PM - 3:00PM

Location: BRIM 311

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...

Seminar: Chemical Principles of Topological Semimetals

10 Jul2018

Speaker: Leslie Schoop, Princeton University

Time: Jul 10, 2018 :: 10:30AM - 11:30AM

Location: BRIM 311

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...

Seminar: High pressure floating zone crystal growth of strongly correlated materials

09 Jul2018

Speaker: Junjie Zhang, Materials Science and Technology Division, Oak Ridge National Laboratory

Time: Jul 9, 2018 :: 11:30AM - 12:30PM

Location: BRIM 311

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...

Seminar: Nano-Fabrication via State-of-the Art Electron Beam Lithography and Device Applications at SUNUM

11 Jun2018

Time: June 11, 2018, BRIM 311, 11:30 am

Location: BRIM 311

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...

Special Seminar
THE THEOREM OF QUANTUM MECHANICS NO GO

29 May2018

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...

Seminar: Tools for in-situ and operando high-resolution microscopy—bench top experiments inside the microscope

22 May2018

Speaker: Julio A. Rodríguez Manzo, Application Scientist at Hummingbird Scientific

Time: Tuesday May 22, 2018 :: 10:30 AM - 12:00 PM

Location: BRIM 311

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...
