Professor Ctirad Uher is the C. Wilbur Peters Collegiate Professor at the University of Michigan in Ann Arbor. Born in Prague, Czech Republic, he graduated from the University of New South Wales, Australia in 1972 and earned his Ph.D. from there in 1979.
He currently teaches in the physics department at the University of Michigan and does research in the field of condensed matter physics. Ctirad Uher was Associate Dean for two years before becoming Chair of the Physics Department in 1994. In 2004, he stepped down from that position. [1] During Uher's administration the Physics Department faculty expanded enormously, from 60 faculty members to 80. Of these 20 new faculty, 19 eventually received tenure. It was also during this time that Martinus Veltman received his Nobel Prize. Before Uher's administration, there were no distinguished professorships in the physics department; afterward, there were six.
It was during Uher's administration that FOCUS (Frontiers in Optical Coherent and Ultrafast Science) was started, a program that continued until 2010. It was funded at first by an NSF grant and later through the MURI (Multidisciplinary University Research Initiative). Thanks in part to FOCUS, the University of Michigan was top-ranked in atomic/molecular/optical physics in the early 2000s.
It was also during Uher's term that the Michigan Center for Theoretical Physics (MCTP) was established, designed to create an intellectual atmosphere conductive to theoretical physicists, a platform for theoretical research. One of the first faculty members hired for the program was Michael Duff, a leading string theorist. The MCTP held several week-long sessions dedicated to specialized topics, for which experts were brought in from other Universities. Gordon Kane was the director of the MCTP for several years.
In 1998 the Program in Nonlinear Studies began, which in 1999 became the Center for the Study of Complex Systems, an interdisciplinary program studying complex systems that reaches out to many other fields including mathematics, biology, and economics.
Uher is a Fellow of the American Physical Society. [2] In 2008, he was chosen for the American Physical Society's Outstanding Referees Program for excellence in peer review. [3]
In 2011, Uher was awarded the Friendship Award by the People's Republic of China. [4]

Thermoelectric materials show the thermoelectric effect in a strong or convenient form.
Skutterudite is a cobalt arsenide mineral containing variable amounts of nickel and iron substituting for cobalt with the ideal formula CoAs3. Some references give the arsenic a variable formula subscript of 2–3. High nickel varieties are referred to as nickel-skutterudite, previously chloanthite. It is a hydrothermal ore mineral found in moderate to high temperature veins with other Ni-Co minerals. Associated minerals are arsenopyrite, native silver, erythrite, annabergite, nickeline, cobaltite, silver sulfosalts, native bismuth, calcite, siderite, barite and quartz. It is mined as an ore of cobalt and nickel with a by-product of arsenic.
The Wannier functions are a complete set of orthogonal functions used in solid-state physics. They were introduced by Gregory Wannier in 1937. Wannier functions are the localized molecular orbitals of crystalline systems.
Lead telluride is a compound of lead and tellurium (PbTe). It crystallizes in the NaCl crystal structure with Pb atoms occupying the cation and Te forming the anionic lattice. It is a narrow gap semiconductor with a band gap of 0.32 eV. It occurs naturally as the mineral altaite.
Oleg Sushkov is a professor at the University of New South Wales and a leader in the field of high temperature super-conductors. Educated in Russia in quantum mechanics and nuclear physics, he now teaches in Australia.
Tin selenide, also known as stannous selenide, is an inorganic compound with the formula SnSe. Tin(II) selenide is a typical layered metal chalcogenide as it includes a group 16 anion (Se2−) and an electropositive element (Sn2+), and is arranged in a layered structure. Tin(II) selenide is a narrow band-gap (IV-VI) semiconductor structurally analogous to black phosphorus. It has received considerable interest for applications including low-cost photovoltaics, and memory-switching devices.
Jozef T. Devreese was a Belgian scientist, with a long career in condensed matter physics. He was professor emeritus of theoretical physics at the University of Antwerp. He died on November 1, 2023.
Marvin Lou Cohen is an American–Canadian theoretical physicist. He is a physics professor at the University of California, Berkeley. Cohen is a leading expert in the field of condensed matter physics. He is widely known for his seminal work on the electronic structure of solids.
Volker Heine FRS is a New Zealand / British physicist. He is married to Daphne and they have three children. Volker Heine is considered a pioneer of theoretical and computational studies of the electronic structure of solids and liquids and the determination of physical properties derived from it.
Picosecond ultrasonics is a type of ultrasonics that uses ultra-high frequency ultrasound generated by ultrashort light pulses. It is a non-destructive technique in which picosecond acoustic pulses penetrate into thin films or nanostructures to reveal internal features such as film thickness as well as cracks, delaminations and voids. It can also be used to probe liquids. The technique is also referred to as picosecond laser ultrasonics or laser picosecond acoustics.
In crystallography, a disclination is a line defect in which there is compensation of an angular gap. They were first discussed by Vito Volterra in 1907, who provided an analysis of the elastic strains of a wedge disclination. By analogy to dislocations in crystals, the term, disinclination, was first used by Frederick Charles Frank and since then has been modified to its current usage, disclination. They have since been analyzed in some detail particularly by Roland deWit.

Interfacial thermal resistance, also known as thermal boundary resistance, or Kapitza resistance, is a measure of resistance to thermal flow at the interface between two materials. While these terms may be used interchangeably, Kapitza resistance technically refers to an atomically perfect, flat interface whereas thermal boundary resistance is a more broad term. This thermal resistance differs from contact resistance because it exists even at atomically perfect interfaces. Owing to differences in electronic and vibrational properties in different materials, when an energy carrier attempts to traverse the interface, it will scatter at the interface. The probability of transmission after scattering will depend on the available energy states on side 1 and side 2 of the interface.
Swift heavy ions are the components of a type of particle beam with high enough energy that electronic stopping dominates over nuclear stopping. They are accelerated in particle accelerators to very high energies, typically in the MeV or GeV range and have sufficient energy and mass to penetrate solids on a straight line. In many solids swift heavy ions release sufficient energy to induce permanently modified cylindrical zones, so-called ion tracks. If the irradiation is carried out in an initially crystalline material, ion tracks consist of an amorphous cylinder. Ion tracks can be produced in many amorphizing materials, but not in pure metals, where the high electronic heat conductivity dissipates away the electronic heating before the ion track has time to form.

The 3ω-method or 3ω-technique, is a measurement method for determining the thermal conductivities of bulk material and thin layers. The process involves a metal heater applied to the sample that is heated periodically. The temperature oscillations thus produced are then measured. The thermal conductivity and thermal diffusivity of the sample can be determined from their frequency dependence.
Rubidium superoxide or rubidium hyperoxide is a chemical compound with the chemical formula RbO2. In terms of oxidation states, the negatively charged superoxide and positively charged rubidium give it a structural formula of Rb+[O2]−.
Europium(II) oxide (EuO) is a chemical compound which is one of the oxides of europium. In addition to europium(II) oxide, there is also europium(III) oxide and the mixed valence europium(II,III) oxide.
